When trying to run qemu-riscv64_smode_defconfig with 32 harts booting
fails. The debug UART shows a message
alloc space exhausted
32 is the current maximum number of harts for machine virt in QEMU 7.0.

The tps65217 PMIC driver is used with am335x SoC based designs.
It is used in the SPL (MLO) as well, so the DM conversion only is

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

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.

On AM64x devices, it is possible to route Main ESM0 error events to MCU
ESM. MCU ESM high error output can trigger the reset logic to reset the
device. So, for these devices we expect two ESM device nodes in the
device tree, one for Main ESM and the another MCU ESM in the device tree.
When these ESM device nodes are properly configired it is possible to
route the Main RTI0 WWDT output to the MCU ESM high output through Main
ESM and trigger a device reset when
CTRLMMR_MCU_RST_CTRL:MCU_ESM_ERROR_RESET_EN_Z is set to '0'.

U-boot is intended to replace linux kernel in android boot image(ABL), and
it's FIT payload to replace initramfs file. The boot process is similar to
boot image with linux:
- android bootloader (ABL) unpacks android boot image
- ABL sets `linux,initrd-start property` in chosen node in unpacked FDT
- ABL sets x0 register to FDT address, and passes control to u-boot
- u-boot reads x0 register, and stores it in `prevbl_fdt_addr` env variable
- u-boot reads `linux,initrd-start` property,
and stores it in `prevbl_initrd_start_addr`
In this way, u-boot bootcmd relies on `prevbl_initrd_start_addr` env
variable, and boils down to `bootm $prevbl_initrd_start_addr`.
If more control on boot process is desired, pack a boot script in
FIT image, and put it to default configuration
What done:
- Rearrange defconfig option order
- Add CONFIG_SAVE_PREV_BL_* options
- Doc updates:
- remove wrong SBOOT memory corruption note, because
memory is changed during u-boot bringup process,
not by SBOOT
- put payload on ramdisk place in abl boot image

Platforms can overwrite the weak definition of spl_mmc_boot_mode() to
determine where to load U-Boot proper from.
For most of them this is a trivial decision based on Kconfig variables,
but it might be desirable the probe the actual device to answer this
question.
Pass the pointer to the mmc struct to that function, so implementations
can make use of that.
