There are three major variants of the AXP PMIC GPIO functionality (plus
PMICs with no GPIOs at all). Except for GPIO3 on the AXP209, which uses
a different register layout, it is straightforward to support all three
variants with a single driver. Do this, and in the process remove the
GPIO-related definitions from the PMIC-specific headers, and therefore
the dependency on AXP_PMIC_BUS.

TOC1 is an container format used by Allwinner's boot0 that can hold
multiple images. It supports encryption and signatures, but that
functionality is not implemented, only the basic "non-secure" subset.
A config file is used to provide the list of data files to include. Its
path is passed as the argument to "-d". It contains sections of the
following form:
[name]
file = /path/to/file
addr = 0x12345678
Specific well-known names, such as "dtb", "opensbi", and "u-boot", are
used by the bootloader to distinguish the items inside the image.
Cover-letter:
tools: mkimage: Add Allwinner TOC1 support
The SPL port for the Allwinner D1 RISC-V SoC will probably take a while
longer than porting U-Boot proper, as none of the relevant drivers are
set up for DM in SPL. In the meantime, we are using[1][2] a fork[3] of
Allwinner's boot0 loader, which they also call "spl" in their BSP. boot0
uses this TOC1 image format.
The vendor tools for generating TOC1 images require a binary config file
generated by their FEX compiler. Instead of trying to support that, I
made up a simple human-readable config file format. I didn't see any
existing platform-agnostic parser for multi-image containers in mkimage.
I am sending this as RFC because it is only of temporary/limited use.
It only works with one specific fork of boot0 which was modified to
"behave" (the the original vendor version monkey-patches a custom header
inside the U-Boot image during boot). So it will be obsolete once U-Boot
SPL is ported. And it is Yet Another Image Format. On the other hand, it
does work, and it is currently being used.

As a first step toward converting this driver to the driver model, use
the ofnode abstraction to replace direct references to the FDT blob.
Using ofnode_read_u32_index removes an extra pair of loops and makes the
allwinner,rb property optional, matching the devicetree binding.

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.

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.

To do this, we set a default of 0 for everyone because there are a
number of cases where we define CONFIG_SYS_MONITOR_LEN but the only
impact is that we set TOTAL_MALLOC_LEN to be CONFIG_SYS_MALLOC_LEN +
CONFIG_ENV_SIZE, so we must continue to allow all boards to set this

directly, if we don't have a real CONFIG_SYS_MONITOR_LEN value.

The imx8mn_beacon board does not use the same memory map as the reference
design from NXP or other imx8mn boards. As such, memory is more limited
in SPL.
Moving SPL_BSS_START_ADDR and SPL_STACK to default locations increases
the amount of available meory for the SPL stack. Doing this allows
the board to no longer define CONFIG_MALLOC_F_ADDR.
Since SYS_LOAD_ADDR also does not align with other boards, move it too.
