Simon Glass 4f6aa3468d scsi: Correct types of scsi_read/write()
The block device expects to see lbaint_t for the blknr parameter. Change
the SCSI read/write functions to suit.

This fixes the following build warnings for coreboot:

cmd_scsi.c: In function ‘scsi_scan’:
cmd_scsi.c:119:30: error: assignment from incompatible pointer type [-Werror]
cmd_scsi.c:120:32: error: assignment from incompatible pointer type [-Werror]

Simon Glass b7a1d13462 bootm: Handle errors consistently
A recent bootm fix left the error path incomplete. If CONFIG_TRACE is
set it may still not be a supported command, so cover that with the
unsupported subcommand print.  Once we handle BOOTM_STATE_OS_GO, we can
just move into the error handler itself, no need for a goto there.

Simon Glass f320a4d845 bootm: Use selected configuration for ramdisk and fdt
If a specific configuraion is selected by the bootm command, e.g. with
'bootm 84000000#recoveryconf' we must honour this for not just the kernel,
but also the ramdisk and FDT.

In the conversion to using a common fit_image_load() function for loading
images from FITs (commits a51ec63 and 53f375f) this feature was lost.
Reinstate it by passing the selected configuration back from
fit_image_load() to boot_get_kernel(), then use this configuration
(which is stored in images->fit_uname_cfg) in both boot_get_ramdisk()
and boot_get_fdt().

Simon Glass fb1b139bb7 bootm: Add the missing PREP stage to bootz and correct image handling
In the recent bootm refactor, the PREP stage was missing in the bootz
command. This causes unpredictable behaviour.

The use of a local variable means that the reset of cmd_bootm.c does not
in fact use the same image structure, so remove this.

Also manually set the OS type to Linux, since this is the only possibility
at present, and we need to select the right boot function.

Tom Rini d366438d8a cmd_bootm.c: Correct BOOTM_ERR_OVERLAP handling
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
existing restriction on negative return values.

Sascha Silbe ff8fef5666 Fix block device accesses beyond 2TiB
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type,
which is required to represent block numbers for storage devices that
exceed 2TiB (the block size usually is 512B), e.g. recent hard drives.

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
changes to all block drivers as the signature of block_read(),
block_write() and block_erase() in block_dev_desc_t changed.

to substitute a signed image from an older FIT version into a newer FIT
(roll-back attack).

Simon Glass 19c402afa2 image: Add RSA support for image signing
RSA provides a public key encryption facility which is ideal for image

Images are signed using a private key by mkimage. Then at run-time, the
images are verified using a private key.

This implementation uses openssl for the host part (mkimage). To avoid
bringing large libraries into the U-Boot binary, the RSA public key
is encoded using a simple numeric representation in the device tree.

Simon Glass d0ae31eb07 Add a 'fake' go command to the bootm command
For tracing it is useful to run as much of U-Boot as possible so as to get
a complete picture. Quite a bit of work happens in bootm, and we don't want
to have to stop tracing before bootm starts.

Add a way of doing a 'fake' boot of the OS - which does everything up to
the point where U-Boot is about to jump to the OS image. This allows
tracing to record right until the end.

Simon Glass 35fc84fa1f Refactor the bootm command to reduce code duplication
At present the bootm code is mostly duplicated for the plain 'bootm'
command and its sub-command variant. This makes the code harder to
maintain and means that changes must be made to several places.

Introduce do_bootm_states() which performs selected portions of the bootm
work, so that both plain 'bootm' and 'bootm <sub_command>' can use the
same code.

Additional duplication exists in bootz, so tidy that up as well. This
is not intended to change behaviour, apart from minor fixes where the
previously-duplicated code missed some chunks of code.

Simon Glass 983c72f479 Clarify bootm OS arguments
At present the arguments to bootm are processed in a somewhat confusing
way. Sub-functions must know how many arguments their calling functions
have processed, and the OS boot function must also have this information.
Also it isn't obvious that 'bootm' and 'bootm start' provide arguments in
the same way.

Adjust the code so that arguments are removed from the list before calling
a sub-function. This means that all functions can know that argv[0] is the
first argument of which they need to take notice.
