Subject: [PATCH 25/90] 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. Let's first enable FIT support before adding extra firmware.
|
|
|
|
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.
|
|
|
|
Cover-letter:
|
|
sunxi: SPL FIT support for 32-bit sunxi SoCs
|
|
This series makes the necessary changes so 32-bit sunxi SoCs can load
|
|
additional device trees or firmware from SPL along with U-Boot proper.
|
|
|
|
There was no existing binman entry property that put the FIT at the
|
|
right offset. The minimum offset is 32k, but this matches neither the
|
|
SPL size (which is no more than 24k on some SoCs) nor the FIT alignment
|
|
(which is 512 bytes in practice due to SPL size constraints). So instead
|
|
of adding a new property, I fixed what is arguably a bug in the offset
|
|
property -- though this strategy will not work if someone is
|
|
intentionally creating overlapping entries.
|
|
