Subject: [PATCH 04/13] sunxi: Enable SPL FIT loading for 32-bit SoCs
|
|
|
|
Now that 32-bit SoCs can load U-Boot proper (and possibly other
|
|
firmware) from a FIT, use this method by default. SPL_FIT_IMAGE_TINY is
|
|
required to stay within the 24 or 32 KiB SPL size limit on early SoCs;
|
|
for consistency, enable it everywhere.

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.
|
|
Crust (SCP firmware) has support for A33 and H3, and H3 also needs to
|
|
load an eGon blob to support CPU 0 hotplug (a silicon bug workaround).
|
|
|
|
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 consistency, enable that option everywhere.
|
|
|
|
After this series is applied, we can increase SPL_MAX_SIZE for H6 and
|
|
newer SoCs, both 32-bit (e.g. A50, T113) and 64-bit. I did not do that
|
|
yet because there is some discussion to be had about the correct value:
|
|
it must be adjusted to guarantee return-to-FEL functionality, and the
|
|
exact adjustment depends on the sunxi-fel tool implementation.
|
