Assorted fixes, refactorings and additions that are ready, and shave
off some load from upcoming series'.
Improves MMC performance on D1/T113 (missed clock divider), enables
eMMC access on the H616 family (never worked, many thanks to Jernej for
the fix!), DRAM detection fixes for the H616 (now reportedly stable).
Some patches for the upcoming Allwinner A133 SoC support: a few
refactorings, plus the DM clock and pinctrl driver. The DRAM init
routines work, but need some more polishing, that also holds back the
actual enablement patch, which will hopefully follow for v2025.07 still.
Also some preparatory patches for the Allwinner A523 SoC support, for
now just to improve the FEL save/restore code. There will be more patches
coming up for this, ideally also in the coming cycle still.
Gitlab CI passed, and I booted that briefly on some boards.

Because the Allwinner BootROM always runs in AArch32, even on ARMv8 SoCs,
we need to switch to AArch64 first, but also need to save the CPU state,
when we later may need to return to the BootROM, for continuing with the
FEL USB protocol. This is done in 32-bit code, which we include into the
AArch64 boot assembly file as a series of .word directives, containing
the encoded AArch32 instructions. To be able to change and verify that
code, we also kept an assembly file with the respective 32-bit code, but
just for reference.
As this code is never compiled or assembled - it's just for
documentation - it became stale over time: we didn't really update this
along with the changes we made to the boot code. In particular the FEL
save code was completely missing.
Update that 32-bit assembly file, to match the current version used in
boot0.h, including the FEL save routine. Also update the build
instructions in the comments, to give people an actual chance to
assemble this code.

To be able to return to the BootROM when booting via the FEL USB
protocol, we need to save the CPU state very early, which we need to do
in the embedded AArch32 code. At the moment the pointer to the buffer for
that state is located *after* the code, which makes the PC relative
code fragile: adding or removing instructions will change the distance
to that pointer variable.
The "new" Allwinner A523 SoC requires more state to be saved (GICv3
system registers), but we must do that *only* on that SoC. Conditional
compilation sounds like the easiest solution, but would mean that the
distance to that pointer would change.
Solve this rather easily by moving the pointer to the *front* of the
code: we load that pointer in the first instructions, so the distance
would always stay the same. Later in the code we won't need PC relative
addressing anymore, so this code can grow or shrink easily, for instance
due to conditional compilation.

To return a 64-bit Allwinner chip back to the 32-bit BootROM code, we
have some embedded AArch32 code that restores the CPU state, before
branching back to the BootROM. At the moment the pointer to the buffer

code fragile: adding or removing instructions will change the distance
to that pointer variable.

It turns out that checking just one write is not enough. Due to
unexplained reasons scan procedure detected double the size. By making
16 dword writes and comparisons that never happens.
New procedure is also inverted. Instead of writing two different values
to base address and some offset and then reading both and comparing
values, simplify this by writing pattern at the base address and then
search for this pattern at some offset.

Since there is quite a few possible DRAM configurations in terms of bus
width, rank and rows and columns count, size detection algorithm must be
very careful not to test combination which would be bigger than H616 is
actually capable of handling.
Ideally, we should always detect memory aliasing, even for 4 GB memory
size, which is the maximum amount of memory that H616 is capable of
handling. For this reason, we have to configure minimum amount of
supported rows when testing for columns and vice versa. This way test
code will never step out of 4 GB boundary.
While at it, check for 17 rows maximum. This aligns code with BSP DRAM
driver. There is probably no such configuration which would make sense
with 4 GB memory.

Most Allwinner SoCs (used on 107 out of 172 boards) use a default CPU
frequency of 1008 MHz during the initial setup in the SPL.

Some of the X-Power AXP PMICs can be ordered with an alternative I2C
address, for instance an AXP717 could be shipped with address 0x34 or
with address 0x35. Similarly the AXP803 lists two possible addresses.
For DM (DT) based drivers this is no problem, but the Allwinner SPL
code relies on exactly one hardcoded address per PMIC so far.
Add a Kconfig variable that holds the I2C address used by the PMIC
accessed in the SPL, and provide the (mostly only one) supported address
as its default, for the PMICs we use. Boards using the other address
can easily set this in their defconfig.
This effectively moves the hardcoding from C code to Kconfig.
That enables to use the AXP717 on some boards with the new Allwinner
A523 chip, which use the other I2C address there.

On the Allwinner D1/R528/T113-s3 SoCs (NCAT2) the factors encoded in
the PLL register describe the doubled clock rate, as in the other SoCs.
Correct for that by always dividing the calculated rate by 2, except on
the H6, where we need a divisor of 4 (no change here).
This corrects the PERIPH0 clock rate as read by the MMC driver, and
actually doubles the MMC performance on those NCAT2 chips.

Most MSM8916 devices shipped without PSCI support. The history is quite
nuanced (a good overview can be found in [1]), but the end result is
that the upstream DTs for this SoC pretend that PSCI exists, and it's
expected that the bootloader handles the case where it doesn't. This is
codified by the de-facto bootloader for MSM8916 devices, lk2nd [2].
So we handle it here by deleting the /psci node if we detect the absence
of PSCI. We need to do this early to ensure sysreset works correctly,
since the PSCI firmware driver is PRE_RELOC and binds the PSCI sysreset
driver.
Additionally, show_psci_version is updated to check that PSCI exists.
Currently this banner outputs "PSCI: 65535.65535" on devices without
PSCI support, which isn't very useful :)

qcom_parse_memory is updated to return a -ENODATA error if the passed

board_fdt_blob_setup first tries to call qcom_parse_memory with the
internal FDT (if present+valid). If that fails, it tries again with the
external FDT (again, if present+valid).
When booting with an internal FDT from upstream, it's likely that this
change results in a slight performance hit, since virtually all upstream
qcom DTs lack a fully specified memory node. The impact should be
negligible, though.
