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.

Now that this functionality is modeled using the device tree and
regulator uclass, the named GPIO is not referenced anywhere. Remove
it, along with the rest of the support for AXP virtual GPIOs.

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.

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.

Most Allwinner sunxi SoCs have separate boot ROMs in non-secure and
secure mode. The "non-secure" or "normal" boot ROM (NBROM) uses the
existing sunxi_egon image type. The secure boot ROM (SBROM) uses a
completely different image type, known as TOC0.
A TOC0 image is composed of a header and two or more items. One item
is the firmware binary. The others form a chain linking the firmware
signature to the root-of-trust public key (ROTPK), which has its hash
burned in the SoC's eFuses. Signatures are made using RSA-2048 + SHA256.
The pseudo-ASN.1 structure is manually assembled; this is done to work
around bugs/quirks in the boot ROM, which vary between SoCs. This TOC0
implementation has been verified to work with the A50, A64, H5, H6,
and H616 SBROMs, and it may work with other SoCs.
Series-changes: 2
- Moved certificate and key item structures out of sunxi_image.h
- Renamed "main" and "item" variables for clarity
- Improved error messages, and added a hint about key generation
- Added a comment explaining the purpose of the various key files
- Mentioned testing this code on A50 in the commit message
Series-changes: 3
- Removed TOOLS_LIBCRYPTO selection for sunxi, since most boards
do not need it
- Added __packed to all new "ABI" structs

The last board that used to set CONFIG_LYNXKDI has been removed in
commit 242836a893ae ("powerpc: ppc4xx: remove pcs440ep support"),
doc/README.lynxkdi only talks about a MPC8260 board being supported,
and the mpc8260 support has been removed four years ago in commit
2eb48ff7a210d ("powerpc, 8260: remove support for mpc8260") already,
and common/lynxkdi.c only consists of an "#error" statement these

It is pretty strange that the pxe code uses the 'filesize' environment
variable find the size of a file it has just read.
Partly this is because it uses the command-line interpreter to parse its
request to load the file.
As a first step towards unwinding this, return it directly from the
getfile() function. This makes the code a bit longer, for now, but will be
cleaned up in future patches.
