Simon Glass 836ac74c29 malloc_simple: Add debug() information
It's useful to get a a trace of memory allocations in early init. Add a
debug() call to provide that. It can be enabled by adding '#define DEBUG'
to the top of the file.

The changes in ed6a5d4 unintentionally broke support for reading the

decision on which environment to use is now moved to env_relocate_spec.
This is done for both the "redundant env" and the "single env" case.

Tom Rini 1fec3c5d83 common/image.c: Make boot_get_ramdisk() perform a check for Android images
In 2dd4632 the check for where a ramdisk is found on an Android image
was got moved into the "normal" loop here, causing people to have to
pass the kernel address in the ramdisk address location in order to have
Android boot still.  This changed previous behavior so perform a check
early in the function to see if we have an Android image and if so use
that as where to look for the ramdisk (which is what the rest of the
code here expects).  We allow for this to still be overridden with an
explicit ramdisk address to be passed as normal.

Julius Werner 027b728d4a Add support for LZ4 decompression algorithm
This patch adds support for LZ4-compressed FIT image contents. This
algorithm has a slightly worse compression ration than LZO while being
nearly twice as fast to decompress. When loading images from a fast
storage medium this usually results in a boot time win.

Sandbox-tested only since I don't have a U-Boot development system set
up right now. The code was imported unchanged from coreboot where it's
proven to work, though. I'm mostly interested in getting this recognized
by mkImage for use in a downstream project.

Bernhard Nortmann 4917c061a2 net: avoid eth_unregister() call when function is unavailable
CONFIG_NETCONSOLE causes common/bootm.c to call eth_unregister()
for network device shutdown. However, with CONFIG_DM_ETH this
function is no longer defined.

This is a workaround to avoid the call in that case, and solely
rely on eth_halt(). In case this is insufficient, a proper way
to unregister / remove network devices needs to be implemented.

At present malloc.h is included everywhere since it recently was added to
common.h in this commit:

   4519668 mtd/nand/ubi: assortment of alignment fixes

This seems wasteful and unnecessary. We have been trying to trim down
common.h and put separate functions into separate header files and that
change goes in the opposite direction.

Move malloc_cache_aligned() to a new header so that this can be avoided.
The header would perhaps be better named as alignmem.h but it needs to be
included after common.h and people might be confused by this. With the name
memalign.h it fits nicely after malloc() in most cases.

Masahiro Yamada 0f9258228e of: clean up OF_CONTROL ifdef conditionals
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL.  We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

 #ifdef CONFIG_OF_CONTROL
 # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
 #  define OF_CONTROL 0
 # else
 #  define OF_CONTROL 1
 # endif
 #else
 # define OF_CONTROL 0
 #endif

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute.  It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

in crt0.S and cro0_64.S for ARM at least.

The fix is not complicated but it seems safer to revert this for now.

This reverts commit 2afddae075.

Ravi Babu 7dd0174467 env: use cache line aligned memory for flash read
Use memalign() with ARCH_DMA_MINALIGN to allocate read buffers.
This is required because, flash drivers may use DMA for read operations
and may have to invalidate the buffer before read.

Simon Glass f0c7d9c746 x86: Switch to using generic global_data setup
There is quite a bit of assembler code that can be removed if we use the
generic global_data setup. Less arch-specific code makes it easier to add
new features and maintain the start-up code.

Drop the unneeded code and adjust the hooks in board_f.c to cope.

Simon Glass 1fed87db6a Allow arch-specific setting of global_data in board_init_f_mem()
At present we have a simple assignment to gd. With some archs this is
implemented as a register or through some other means; a simple assignment
does not suit in all cases.

Change this to a function and add documentation to describe how this all
works.
