common/spl: Drop [ST]PL_HASH_SUPPORT in favor of [ST]PL_HASH

2021-09-08T20:11:46+00:00

All of these configs exist. Stick to using CONFIG_[ST]PL_HASH, and drop all
references to CONFIG_[ST]PL_HASH_SUPPORT.  This means we need for
CHAIN_OF_TRUST to select SPL_HASH now.

common: Remove unused CONFIG_FIT_SHAxxx selectors

2021-09-08T20:10:34+00:00

Originally CONFIG_FIT_SHAxxx enabled specific SHA algos for and only
for hash_calculate() in common/image-fit.c. However, since commit
14f061dcb1 ("image: Drop IMAGE_ENABLE_SHAxxx"),
the correct selector was changed to CONFIG_SHAxxx.

The extra "_FIT_" variants are neither used, nor needed. Remove them.
One defconfig disables FIT_SHA256, which is now changed to 'SHA256'.

CMD_MVEBU_BUBT needs to select select SHA256 to avoid undefined
references to "sha256_*()". bubt.c needs sha256, so this selection is
correct. It is not clear why this problem did not manifest before.

Note that SHA selection in SPL is broken for this exact reason. There
is no corresponding SPL_SHAxxx. Fixing this is is beyond the scope of
this change.

Also note that we make CONFIG_FIT now imply SHA256, to make up for
FIT_SHA256 previously being a default y option.

arm: mvebu: Load U-Boot proper binary in SPL code based on kwbimage header

2021-07-31T07:59:58+00:00

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
proper starts.

SPL: Add support for parsing board / BootROM specific image types

2021-07-31T07:49:32+00:00

Platform specific BootROM may use its own image type for loading SPL or
U-Boot proper. In some cases it makes sense to not use BootROM supplied
code for booting U-Boot proper but rather to use U-Boot SPL for this,
e.g. when U-Boot SPL can load U-Boot proper faster than BootROM. In this
case it is required for platform board code to parse and load U-Boot in
BootROM specific image type.

This change adds support for parsing platform / board / BootROM specific
image types via weak function spl_parse_board_header() which is called
before marking boot image as a raw.

SPL: Add support for specifying offset between header and image

2021-07-31T07:49:32+00:00

Some image types (e.g. kwbimage v1) store the offset to SPL binary and
offset to U-Boot proper binary in their headers. To avoid reading SPL
binary when loading U-Boot proper, add support for specifying offset in
struct spl_image_info, which defines the offset from the beginning of
the header and the beginning of the executable data.

Initial support is added only for SPI, MMC and SATA code. We can extend
it later if needed.
