The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

The following shell command fails:
if test -z "$x"; then echo "zero"; else echo "non-zero"; fi
(assuming $x does not exist, it prints "non-zero" rather than "zero").
... since "$x" expands to nothing, and the argument is completely
dropped, causing too few to be passed to -z, causing cmd_test() to
error out early.
This is because when variable expansions are processed by make_string(),
the expanded results are concatenated back into a new string. However,
no quoting is applied when doing so, so any empty variables simply don't
generate any parameter when the combined string is parsed again.
Fix this by explicitly replacing quoting any argument that was originally
quoted when re-generating a string from the already-parsed argument list.
This also fixes loss of whitespace in commands such as:
setenv space " "
setenv var " 1${space}${space} 2 "

Now we are ready to switch over to real Kbuild.
This commit disables temporary scripts:
scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
scripts/{Makefile.build,Makefile.host,Makefile.lib}.
This switch is triggered by the line in scripts/Kbuild.include
-build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
+build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

Currently, ! can only be parsed as the first operator in an expression.

$ if test ! 1 -eq 2 -a ! 3 -eq 4; then echo yes; else echo no; fi

similarly to -a and -o.

This better mirrors the behaviour of bash, for example:
$ if test -z = -z; then echo yes; else echo no; fi

This is parsed as a string comparison of "-z" and "-z", since the check
for the binary "=" operator occurs first. Without this change, the
command would be parsed as a -z test of "-", followed by a syntax error;
a trailing -z without and operand.
This is a behavioural change, but I believe any commands affected were
previously invalid or bizarely formed.

do_test() currently uses strcmp() twice to determine which operator is
present; once to determine how many arguments the operator needs, then
a second time to actually decode the operator and implement it.
Rewrite the code so that a table lookup is used to translate the operator
string to an integer, and use a more efficient switch statement to decode
and execute the operator.
This approach also acts as enablement for the following patches.

People who write (or scripts that auto-generate) extlinux.conf don't
want to know about HW-specific information such as FDT filenames. Create
a new extlinux.conf tag "fdtdir" that specifies only the directory where
FDT files are located, and defer all knowledge of the filename to U-Boot.
The algorithm implemented is:
==========
if $fdt_addr_r is set:
if "fdt" tag was specified in extlinux.conf:
load the FDT from the filename in the tag
else if "fdtdir" tag was specified in extlinux.conf:
if "fdtfile" is set in the environment:
load the FDT from filename in "$fdtfile"
else:
load the FDT from some automatically generated filename
if no FDT file was loaded, and $fdtaddr is set:
# This indicates an FDT packaged with firmware
use the FDT at $fdtaddr
==========
A small part of an example /boot/extlinux.conf might be:
==========
LABEL primary
LINUX zImage
FDTDIR ./
LABEL failsafe
LINUX bkp/zImage
FDTDIR bkp/

This is only required for "PIC" relocation and doesn't apply to modern
"PIE" relocation which does data relocation as well as code.
"init_sequence_r" is just an array that consists of compile-time
adresses of init functions. Since this is basically an array of integers
(pointers to "void" to be more precise) it won't be modified during
relocation - it will be just copied to new location as it is.
As a consequence on execution after relocation "initcall_run_list" will
be jumping to pre-relocation addresses. As long as we don't overwrite
pre-relocation memory area init calls are executed correctly. But still
it is dangerous because after relocation we don't expect initially used
memory to stay untouched.

There is no obvious reason why standalone is handled with a special case.
Adjust the code so that standalone has a normal OS boot function. We still
need a special case for when the function returns, but at least we can
avoid the main problem.
This is intended to fix the reported:

The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.
Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)
Following proposal for an implementation:
- new field that reflects CSD field DSR_IMP in struct mmc
- new field for design specific DSR value in struct mmc
- board code can set DSR value in mmc struct just after registering an controller
- mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set
Additionally the mmc command is extended to make is possible to play around with different
DSR values.
The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default
DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for
instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after
calling fsl_esdhc_initialize() for the eMMC.

Commit d7884e047d does not go far enough.
There is still at least one call chain that can result in a crash.
The do_tftpb(), do_ext2load(), and do_get_fat() functions expect a valid

because eventually boot_get_kernel() will be called with a NULL cmdtp:
do_tftpb() -> netboot_common() -> bootm_maybe_autostart() -> do_bootm()
-> do_bootm_states() -> bootm_find_os() -> boot_get_kernel()
Around line 991 in cmd_bootm.c, boot_get_kernel() will dereference the
null pointer, and the board will crash.

This allows you to write data to an UBI volume when the amount of memory
available to write that data from is less than the total size of the
data. For example, you may split a root filesystem UBIFS image into
parts, provide the total size of the image to the first write.part
command and then use multiple write.part commands to write the
subsequent parts of the volume. This results in a sequence of commands
akin to:
ext4load mmc 0:1 0x80000000 rootfs.ubifs.0
ubi write.part 0x80000000 root 0x08000000 0x18000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.1
ubi write.part 0x80000000 root 0x08000000
ext4load mmc 0:1 0x80000000 rootfs.ubifs.2
ubi write.part 0x80000000 root 0x08000000

As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)
This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load". In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.
Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble. Stephen Warren comments (see
[1]):
I suppose you can change the behaviour if you want; anyone
writing "0x..." for their values presumably won't be
affected, and if people really do assume all values in U-Boot
are in hex, presumably nobody currently relies upon using
non-prefixed values with the generic load command, since it
doesn't work like that right now.

Netconsole calls eth_halt() before giving control to another operating

But the state machine of netconsole don't take it into account.
Thus, netconsole calls network functions of an halted network device,
making the whole system freeze.
Rather than modifying the state machine of netconsole, we just unregister

A plain bootm used to call the architecture specific boot function with
no flags, but was modified by commit 35fc84fa "Refactor the bootm
command to reduce code duplication" to call the architecture specific
boot function multiple times with various flags in sequence. The
BOOTM_STATE_OS_CMDLINE flag was not used, indeed it seems that at least
ARM prepares the command line on BOOTM_STATE_OS_PREP. However on MIPS
since commit 59e8cbdb "MIPS: bootm: refactor initialisation of kernel
cmdline" the command line is not prepared in response to a
BOOTM_STATE_OS_PREP flag, only on BOOTM_STATE_OS_CMDLINE or a call with
no flags. The end result is that a combination of those 2 commits leads
to MIPS boards booting kernels with no command line arguments.
An extra invocation of the architecture specific boot function with
BOOTM_STATE_OS_CMDLINE fixes this.

With 35fc84fa1 [Refactor the bootm command to reduce code duplication]
we stopped checking the return value of bootm_load_os (unintentionally!)
and simply returned if we had a non-zero return value from the function.
This broke the valid case of a legacy image file of a single kernel
loaded into an overlapping memory area (the default way of booting
nearly all TI platforms).
The best way to fix this problem in the new code is to make
bootm_load_os be the one to see if we have a problem with this, and if
it's fatal return BOOTM_ERR_RESET and if it's not BOOTM_ERR_OVERLAP, so
that we can avoid calling lmb_reserve() but continue with booting. We
however still need to handle the other BOOTM_ERR values so re-work
do_bootm_states so that we have an error handler at the bottom we can
goto for problems from bootm_load_os, or problems from the other callers
(as the code was before). Add a comment to do_bootm_states noting the

For some obscure reason, the current U-Boot code uses lbaint_t for the
number of blocks to read (a rather optimistic estimation of how RAM
sizes will evolve), but not for the starting address. Trying to access
blocks beyond the 2TiB boundary will simply wrap around and read a
block within the 0..2TiB range.
We now use lbaint_t for block start addresses, too. This required

adjust_size_for_badblocks reduces the operation size to account
for the block skipping done by the read/write functions when an
interval (partition name or whole chip) is specified rather than a data
amount.
Erase does not do block skipping, except for erase.spread which takes
a data amount rather than an interval (and thus already does not call
adjust_size_for_badblocks). Calling adjust_size_for_badblocks when
block skipping is not done means that if bad blocks are present,
the "nand erase.part" and "nand erase.chip" commands will fail to erase
blocks at the end of the interval.

This is useful when a single board may be stuffed with different eMMC

2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in

Some ARM compilers may emit code that makes unaligned accesses when
faced with constructs such as:

Replace this with a strcpy() call instead to avoid this. strcpy() is
used here, rather than replacing all usage of the mac variable with the
string itself, since the loop itself sprintf()s to the variable each
iteration, so strcpy() is doing basically the same thing.

simple-framebuffer is a new device tree binding that describes a pre-
configured frame-buffer memory region and its format. The Linux kernel
contains a driver that supports this binding. Implement functions to
create a DT node (or fill in an existing node) with parameters that
describe the framebuffer format that U-Boot is using.
This will be immediately used by the Raspberry Pi board in U-Boot, and
likely will be used by the Samsung ARM ChromeBook support soon too. It
could well be used by many other boards (e.g. Tegra boards with built-in

Much of the image code uses addresses as ulongs and pointers interchangeably,

This doesn't work with sandbox, which has a U-Boot RAM buffer which is
separate from the host machine's memory.
Adjust the cost so that translating from a U-Boot address to a pointer uses
map_sysmem(). This allows bootm to work correctly on sandbox.
