It turns out that it is not necessary to declare the VSELECT signal as
GPIO and let the PMIC driver set it to a fixed high level. This switches
the voltage between 3.3V and 1.8V by setting the PMIC register for LDO5
accordingly.
Instead we can do it like other boards already do and simply mux the
VSELECT signal of the USDHC interface to the pin. This makes sure that
the correct voltage is selected by setting the PMIC's SD_VSEL input
to high or low accordingly.

Clock patches for 2023.01
This contains various fixes (some long overdue) for the next release.
Beside some rather unexciting sync of the DTs from the kernel tree, and
some Kconfig cleanup, there are some improvements for the ARMv5 Allwinner
family, to support boards with the F1C200s (64MB DRAM) better. We will

There is also support for the X96 Mate TV Box, featuring the H616 SoC and
a full 4GB of DRAM.
Also we found the secret to enable SPI booting on the H616 (pin PC5 must
be pulled to GND), so the SPI boot support patch is now good to go.
Passed the gitlab CI, plus briefly tested on Pine64-LTS, LicheePi Nano,
X96 Mate and OrangePi Zero.

This causes the SPL version of QEMU 'virt' U-Boot does not boot Linux
kernel anymore. In that case, OpenSBI is loaded and runs at 0x81000000,
and it creates a 512KiB PMP window from that address. When booting
the Linux kernel, moving kernel to its linking address 0x80200000
overlaps the PMP window, and a PMP access failure is raised.

The default load addresses for the various payloads (kernel, DT,
ramdisk) on systems with just 32MB of DRAM have some issues:
For a start the preceding comment doesn't match the actual values:
apparently they were copied from the 64MB S3 layout, then halved, but
since 0x5 is NOT the half of 0x10, they don't match up.
Also those projected maximum sizes are quite restrictive: it's not easy
to build a compressed kernel image with just 4MB. The only defconfig in
mainline Linux that supports the F1C100s (the only 32MB user so far)
creates a 6MB compressed / 15MB uncompressed kernel.
Rearrange the default load addresses to accommodate such a kernel: we
allow an 7MB/16MB kernel, and up to 5MB of ramdisk, stuffing the smaller
binaries like the DTB towards the end, just before the relocated U-Boot.
Shrink the size for DTB and scripts on the way, there is no need for
allowing up to 512K for them.

Traditionally we assumed that every Allwinner board would come with at
least 256 MB of DRAM, and set our DRAM layout accordingly. This affected
both the default load addresses, but also U-Boot's own address
expectations (like being loaded at 160 MB).
Some SoCs come with co-packaged DRAM, but only provide 32 or 64MB. So
far we special-cased those *chips*, as there was only one chip per DRAM
size. However new chips force us to take a more general approach.
Introduce a Kconfig symbol, which provides the minimum DRAM size of the
board. If nothing else is specified, we use 256 MB, and default to
smaller values for those co-packaged SoCs.
Then select the different DRAM maps according to this new symbol, so
that different SoCs with the same DRAM size can share those definitions.
Inspired by an idea from Icenowy.
This is just refactoring: compiled for all boards before and after this
patch: the binaries were identical.
