Subject: [PATCH 03/13] sunxi: binman: Enable SPL FIT loading for 32-bit SoCs
|
|
|
|
Now that Crust (SCP firmware) has support for H3, we need a FIT image to
|
|
load it. H3 also needs to load a SoC-specific eGon blob to support CPU 0
|
|
hotplug.
|
|
|
|
Update the binman description to work on either 32-bit or 64-bit SoCs:
|
|
- Make BL31 optional, since it is not used on 32-bit SoCs (though BL32
|
|
may be used in the future).
|
|
- Explicitly set the minimum offset of the FIT to 32 KiB, since SPL on
|
|
some boards is still only 24 KiB large even with FIT support enabled.
|
|
CONFIG_SPL_PAD_TO cannot be used because it is not defined for H616.
|
|
|
|
FIT unlocks more features (signatures, multiple DTBs, etc.), so enable
|
|
it by default. A10 (sun4i) only has 24 KiB of SRAM A1, so it needs
|
|
SPL_FIT_IMAGE_TINY. For simplicity, enable that option everywhere.
|
