At present we do support allocating the bloblist but the Kconfig is a bit
strange, since we still have to specify an address in that case. Partly
this is because it is a pain to have CONFIG options that disappears when
its dependency is enabled. It means that we must have #ifdefs in the code,
either in the C code or header file.
Make use of IF_ENABLED_INT() and its friend to solve that problem, so we
can separate out the location of bloblist into a choice. Put the address
and size into variables so we can log the result.
Add the options for SPL as well, so we can use CONFIG_IS_ENABLED().

The hash algorithm selection was streamlined in commit 92055e138f
("image: Drop if/elseif hash selection in calculate_hash()"). Said
commit kept the call to cpu_to_uimage() to convert the CRC to big
endian format.
This would have been correct when calling crc32_wd(). However, the
->hash_func_ws member of crc32 points to crc32_wd_buf(), which already
converts the CRC to big endian. On a little endian host, doing both
conversions results in a little-endian CRC. This is incorrect.
To remedy this, simply drop the call to cpu_to_uimage(), thus only
doing the byte-order conversion once.

We are not guaranteed to have the padding_pkcs_15_verify symbol since
commit 92c960bc1d ("lib: rsa: Remove #ifdefs from rsa.h"), and
commit 61416fe9df ("Kconfig: FIT_SIGNATURE should not select RSA_VERIFY")
The padding_algos only make sense with RSA verification, which can now
be disabled in lieu of ECDSA. In fact this will lead to build failures
because of the missing symbol mentioned earlier.
To resolve this, move the padding_algos to a linker list, with
declarations moved to rsa_verify.c. This is consistent with commit
6909edb4ce ("image: rsa: Move verification algorithm to a linker list")
One could argue that the added #ifdef USE_HOSTCC is ugly, and should
be hidden within the U_BOOT_PADDING_ALGO() macro. However, this would
be inconsistent with the "cryptos" list. This logic for was not
previously explored:
Without knowledge of the U_BOOT_PADDING_ALGO() macro, its use is
similar to something being declared. However, should #ifndef
USE_HOSTCC be part of the macro, it would not be obvious that it
behaves differently on host code and target code. Having the #ifndef
outside the macro makes this obvious.
Also, the #ifdef is not always necessary. For example ecda-verify
makes use of U_BOOT_CRYPTO_ALGO() without any accompanying #ifdefs.
The fundamental issue is a lack of separation of host and target code
in rsa_verify. Therefore, the declaration of a padding algo with the
external #ifdef is more readable and consistent.

calculate_hash() would try to select the appropriate hashing function
by a if/elseif contruct. But that is exactly why hash_lookup_algo()
exists, so use it instead.
This does mean that we now have to 'select HASH' to make sure we get
the hash_lookup_algo() symbol. However, the change makes sense because
even basic FITs will have to deal with "hash" nodes.
My only concern is that the 'select SPL_HASH' might cause some

MD5 is being called directly in some places, but it is not available
via hash_lookup_algo("md5"). This is inconsistent with other hasing
routines. To resolve this, add an "md5" entry to hash_algos[].
The #ifdef clause looks funnier than those for other entries. This is
because both MD5 and SPL_MD5 configs exist, whereas the other hashes
do not have "SPL_" entries. The long term plan is to get rid of the
ifdefs, so those should not be expected to survive much longer.
The md5 entry does not have .hash_init/update/finish members. That's
okay because hash_progressive_lookup_algo() will catch that, and
return -EPROTONOSUPPORT, while hash_lookup_algo() will return the
correct pointer.

One defconfig disables FIT_SHA256, which is now changed to 'SHA256'.
CMD_MVEBU_BUBT needs to select select SHA256 to avoid undefined

correct. It is not clear why this problem did not manifest before.

Now that proper load and execution addresses are set in v1 kwbimage we
can use it for loading and booting U-Boot proper.
Use the new spl_parse_board_header() function to implement parsing the
kwbimage v1 header. Use information from this header to locate offset and
size of the U-Boot proper binary, instead of using the legacy U-Boot
header which is prepended to the U-Boot proper binary stored at fixed
offset. This has the advantage that we do not need to relay on legacy
U-Boot header anymore and therefore U-Boot proper binary can be stored at
any offset, as is the case when loading & booting U-Boot proper by
BootROM. The CONFIG_SYS_U_BOOT_OFFS option is therefore not used by SPL
code anymore.
Also allow to compile U-Boot SPL without CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_MMC_SUPPORT or CONFIG_SPL_SATA_SUPPORT set. In this case
BootROM is used for loading and executing U-Boot proper. This reduces the
size of U-Boot's SPL image. By default these config options are enabled
and so BootROM loading is not used. In some cases BootROM reads from SPI
NOR at lower speed than U-Boot SPL. So people can decide whether they
want to have smaller SPL binary at the cost of slower boot.
Therefore dependency on CONFIG_SPL_DM_SPI, CONFIG_SPL_SPI_FLASH_SUPPORT,
CONFIG_SPL_SPI_LOAD, CONFIG_SPL_SPI_SUPPORT, CONFIG_SPL_DM_GPIO,
CONFIG_SPL_DM_MMC, CONFIG_SPL_GPIO_SUPPORT, CONFIG_SPL_LIBDISK_SUPPORT,
CONFIG_SPL_MMC_SUPPORT, CONFIG_SPL_SATA_SUPPORT and
CONFIG_SPL_LIBDISK_SUPPORT is changed from strict to related "imply"
(which can be selectivelly turned off and causes booting via BootROM).
Options CONFIG_SYS_SPI_U_BOOT_OFFS,
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR and
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET have to to be set to
zero as they define the location where kwbimage header starts. It is the
location where BootROM expects start of the kwbimage from which it reads,
parses and executes SPL part. The same applies to option
CONFIG_SPL_SATA_RAW_U_BOOT_SECTOR, which has to be set to one.
Update all config files to set correct values of these options and set
CONFIG_SYS_U_BOOT_OFFS to the correct value - the offset where U-Boot
