This is the promised second part of the sunxi PR for 2022.04, albeit
technially outside of the merge window. We were working on this full
steam since the beginning of the year, and it deserves to be merged,
I think.
The main attraction is support for the F1C100s SoC, which sports a
venerable ARM926 core. Support for this SoC and the LicheePi Nano board
has been in Linux for years, and U-Boot patches were posted mid last
year already.
The new SoC using ARMv5 also means that the bulk of the new code should
not touch any existing boards, although we did some refactorings first,
of course, which actually cleans up some existing sunxi code.
Compile tested for all 160 sunxi boards, and briefly tested on BananaPi M1,
OrangePi Zero, Pine64 and Pine-H64. Tested by others on their boards,
including F1C100s and F1C200s devices.
The Lichee Pi Nano is a board based on the F1C100s.
Add defconfigs for it.

The BOARD_SIZE_LIMIT applies regardless of ARM64 or not (now), so remove

CONFIG_ENV_IS_IN_MMC, so move that out to simplify the file.

Currently we do some magic "SRAM setup" MMIO writes in s_init(), copied
from the original BSP U-Boot. The comment speaks of this being required
before DRAM access gets enabled, but there is no indication that this
would actually be required that early.
Move this out of s_init(), into board_init_f(). Since this actually only
affects a very few older SoCs, the actual code goes into the cpu/armv7
directory, to move it out of the way for all other SoCs.
This also uses the opportunity to convert some #ifdefs over to the fancy
IS_ENABLED() macros used in actual C code.
We keep the s_init() stub around for now, since armv8's lowlevel_init
still relies on it.

According to their TRMs, Cortex ARMv7 CPUs with SMP support require the
ACTLR.SMPEN bit to be set as early as possible, before any cache or TLB
maintenance operations are done. As we do those things still in start.S,
we need to move the SMPEN bit setting there, too.
This introduces a new ARMv7 wide symbol and code to set bit 6 in ACTLR
very early in start.S, and moves sunxi boards over to use that instead
of the custom code we had in our board.c file (where it was called
technically too late).
In practice we got away with this so far, because at this point all the
other cores were still in reset, so any broadcasting would have been
ignored anyway. But it is architecturally cleaner to do it early, and
we move a core specific piece of code out of board.c.
This also gets rid of the ARM_CORTEX_CPU_IS_UP kludge I introduced a few
years back, and moves the respective logic into the new Kconfig entry.

So far all Allwinner based boards were doing some not-so-lowlevel-setup
in lowlevel's s_init() routine.
This includes the initial clock, timer and pinmux setup, among other
things. This is clearly out of the "absolute bare minimum to get started"
scope that lowlevel_init.S suggests for this function.
Since we have an SPL, which is called right after s_init(), move those
calls to our board_init_f() function. As we overwrite this only for
the SPL, this has the added benefit of not doing this setup *again*
shortly afterwards, when running U-Boot proper.
This makes gpio_init() to be called from the SPL only, so pull this code
into a CONFIG_SPL_BUILD protected part to avoid build warnings.

There is some code that tries to "reset" the SCTLR_ELx register early in
the boot process. The idea seems to be to guarantee some sane settings
that U-Boot actually relies on, for instance running in little-endian
mode, with the MMU off initially.
However the current code has multiple problems:
- For a start, no platform or config defines the symbol that would
enable that code.
- The code itself really only works if the bits that it tries to clear
are already cleared:
- If we run in big-endian mode initially, any previous loads would have
been wrong already. That applies to the (optional) relocation code,
but more prominently to the mask that it uses to clear those bits:
"ldr x1, =0xfdfffffa" looks innocent, but actually involves a memory
access to the literal pool, using the current endianness.
- If we run with the MMU enabled, we are probably doomed already. We
*could* hope that we are running with an identity mapping, but would
need to do some cache maintenance to avoid losing dirty cache lines.
- The idea of doing a read-modify-write of SCTLR is somewhat
questionable to begin with, because as the owner of the current
exception level we should initialise all bits of this register with a
certain fixed value.
- The code is unnecessarily complicated, and the function name is
misspelled.
While those problems *could* admittedly be fixed, the point that is does
not seem to be used at all at the moment tells me we should just remove
this code, and be it to not give a bad example.
If people care, I could introduce some proper SCTLR initialisation code.
We are about to work this out for the boot-wrapper[1] as we speak, but
apparently we got away without doing this in U-Boot ever since, so it
might not be worth the potential trouble.
