Now that the PMIC has a DM driver and binds device tree subnodes, the
GPIO device can be bound that way, instead of from inside board code.
Since the driver still uses the single set of register definitions from
axpXXX.h (as selected by AXPxxx_POWER), it does not differentiate among
the supported compatibles.

These PMICs each have two GPIO pins, and are supported by the axp_gpio
driver. In order to convert the axp_gpio driver to probe using the
device tree, the corresponding device tree nodes must be present. Add
them, following the same binding as the AXP209 and AXP813.

Now that the sunxi_gpio driver handles pull-up/down via the driver
model, we can switch to DM_GPIO for these pins with no loss in
functionality. Since the driver now gets its pin configuration from
the device tree, we can remove the Kconfig symbols.

This adds a new PSCI implementation which communicates with SCP firmware

Add the new option, function IDs, and prototypes for PSCI v1.1

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.
Signed-off-by: Samuel Holland <samuel@sholland.org>
Due to a bug in the H3 SoC, where the CPU 0 hotplug flag cannot be
written, resuming CPU 0 requires using the "Super Standby" code path in
the BROM instead of the hotplug path. This path requires jumping to an
eGON image in SRAM.
Add support to the build system to generate this eGON image and include
it in the FIT, and add code to direct the BROM to its location in SRAM.
Since the Super Standby code path in the BROM initializes the CPU and
AHB1 clocks to 24 MHz, those registers need to be restored after control
passes back to U-Boot. Furthermore, because the BROM lowers the AHB1
clock divider to /1 before switching to the lower-frequency parent,
PLL_PERIPH0 must be bypassed to prevent AHB1 from temporarily running at
600 MHz. Otherwise, this locks up the SoC.

Do not try to send an SGI from CPU 0 to itself. Since FIQs are masked
when entering monitor mode, this will hang. Plus, CPU 0 cannot fully
power itself off anyway. Instead, have it turn FIQs back on and continue
servicing SGIs from other cores.

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.

The MMC controller driver is (and ought to be) the only user of these
register definitions. Put them in a header next to the driver to remove
the dependency on a specific ARM platform's headers.
Due to the sunxi_mmc_init() prototype, the file was not renamed. None of
the register definitions were changed.

For legacy reasons we were defining the card detect GPIO for all sunxi
boards in each board's defconfig.
There is actually no need for a card-detect check in the SPL code (which
consequently has been removed already), and also in U-Boot proper we
have DM code to query the CD GPIO name from the device tree.
That means we don't have any user of that information left, so can
remove the definitions from the defconfigs.

Signed-off-by: Samuel Holland <samuel@sholland.org>
With the introduction of the Allwinner D1, the sunxi board family now
spans multiple architectures (ARM and RISC-V). Since ARCH_SUNXI depends
on ARM, it cannot be used to gate architecture-independent options.
Specifically, this means the board Kconfig file cannot be sourced from
inside the "if ARCH_SUNXI" block.
Introduce a new BOARD_SUNXI symbol that can be selected by both
ARCH_SUNXI now and the new RISC-V SoC symbols when they are added, and
use it to gate the architecture-independent board options.

The initial devicetree for PolarFire SoC incorrectly created a fixed

msspll is not a fixed frequency clock. The actual reference clock on a

Swap the incorrect representation of the msspll out for the actual
