Subject: [PATCH 09/13] sunxi: Enable support for SCP firmware on H3
Now that issues with the BROM have been sorted out, we can implement
PSCI system suspend on H3 by delegating to SCP firmware. Let's start by
including the firmware in the FIT image and starting the coprocessor if
valid firmware is loaded.

Subject: [PATCH 01/13] sunxi: spl: Disable padding from SPL_PAD_TO
Starting with H6, Allwinner removed the artificial 32 KiB SPL size limit
from the boot ROM. Now SPL size is only limited by the available SRAM.
This limit ranges from 152 KiB on H6 to a whopping 2052 KiB on R329. To
take advantage of this additional space, we must increase SPL_MAX_SIZE.
Since we do not want to unnecessarily pad SPL out to these giant sizes,
we must set SPL_PAD_TO to zero. This causes no problems because binman
already takes care of appending the SPL payload at the right offset.

Subject: [PATCH 02/13] binman: Prevent entries in a section from overlapping
Currently, if the "offset" property is given for an entry, the section's
running offset is completely ignored. This causes entries to overlap if
the provided offset is less than the size of the entries earlier in the
section. Avoid the overlap by only using the provided offset when it is
greater than the running offset.
The motivation for this change is the rule used by SPL to find U-Boot on
sunxi boards: U-Boot starts 32 KiB after the start of SPL, unless SPL is
larger than 32 KiB, in which case U-Boot immediately follows SPL.

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.

Subject: [PATCH 03/13] sunxi: binman: Support FIT generation for 32-bit SoCs
Some 32-bit SoCs can use SCP firmware to implement additional PSCI
functionality, such as system suspend. In order to load this firmware
from SPL, we need to generate and use a FIT instead of a legacy image.
Adjust the binman FIT definition so it does not rely on TF-A BL31, as
this is not used on 32-bit SoCs. Instead, after loading the firmware,
U-Boot proper is executed directly.
Series-changes: 2
- Rely on binman min-size instead of using explicit offsets
- Use Kconfig for firmware addresses instead of an #ifdef staircase

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.
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.
