This driver reports the presence/absence of voltage on the PMIC's USB
VBUS pin. This information is used by the USB PHY driver. The
corresponding Linux driver uses the power supply class, which does not
exist in U-Boot. UCLASS_REGULATOR seems to be the closest match.

This board is configured with CONFIG_USB1_VBUS_PIN="PH24", but no
regulator exists in its device tree. Add the regulator, so USB will
continue to work when the PHY driver switches to using the regulator
uclass instead of a GPIO.
Update the device tree here because it does not exist in Linux.

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.

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.

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.

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.

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.

While creating a phy device using phy_device_create(), we need to
provide a valid phyaddr instead of 0 causing phy address being
registered as 0 with mdio bus and shows mdio phy list as below
ZynqMP> mdio list
eth0:
0 - TI DP83867 <--> ethernet@ff0b0000
eth1:
0 - TI DP83867 <--> ethernet@ff0c0000
Also PHY soft reset is being requested on 0 instead of valid
address causing "PHY reset timed out" error.
So add phyaddr argument to phy_connect_phy_id() and to its prototype
to create phy device with valid phyaddress.

A big part is the DM pinctrl driver, which allows us to get rid of quite
some custom pinmux code and make the whole port much more robust. Many
thanks to Samuel for that nice contribution! There are some more or less
cosmetic warnings about missing clocks right now, I will send the trivial
fixes for that later.
Another big chunk is the mkimage upgrade, which adds RISC-V and TOC0
(secure images) support. Both features are unused at the moment, but I
have an always-secure board that will use that once the DT lands in the
kernel.
On top of those big things we have some smaller fixes, improving the
I2C DM support, fixing some H6/H616 early clock setup and improving the
eMMC boot partition support.
The gitlab CI completed successfully, including the build test for all
161 sunxi boards. I also boot tested on a A64, A20, H3, H6, and F1C100
board. USB, SD card, eMMC, and Ethernet all work there (where applicable).
Now that the SPL can safely detect whether it was loaded from an eMMC
boot partition or the normal user data partition, let's enable this
feature on some boards that feature eMMC storage.
That covers the boards where I could test this on, and allows the same
build to be written to an SD card, eMMC user partition, eMMC boot
partition, or into SPI NOR flash.

When the Allwinner BROM loads the SPL from an eMMC boot partition, it
sets the boot source byte to the same value as when booting from the
user data partition. This prevents us from determining the boot source
to load U-Boot proper from the proper partition for sure.
The generic SPL MMC code already looks at the enabled boot partition
number, to load U-Boot proper from the same partition, but this fails
if there is nothing bootable in this partition, as the BROM then
silently falls back to the user data partition, which the SPL misses.
To learn about the actual boot source anyway, we repeat the algorithm
the BROM used to select the boot partition in the first place:
- Test EXT_CSD[179] to check if an eMMC boot partition is enabled.
- Test EXT_CSD[177] to check for valid MMC interface settings.
- Check if BOOT_ACK is enabled.
- Check the beginning of the first sector for a valid eGON signature.
- Load the whole SPL.
- Recalculate the checksum to verify the SPL is valid.
If one of those steps fails, we bail out and continue loading from the
user data partition. Otherwise we load from the selected boot partition.
Since the boot source is needed twice in the boot process, we cache the
result of this test to avoid doing this costly test multiple times.
This allows the very same image file to be put onto an SD card, into the
eMMC user data partition or into the eMMC boot partition, and safely
loads the whole of U-Boot from there.
