Improve documentation. Notably we remove all the board names from the
feature matrix to reduce table width. SoC types have been added to the
titles in individual board documents so readers can still correlate a
board against the features. This makes it easier to add new boards to

Add support for both the BananaPi BPI-CM4 module and the BananaPi
baseboard which is compatible with the RaspberryPi CM4IO baseboard.
The BananaPi BPI-CM4 module follows the CM4 specifications at [1],
but with a single HDMI port and a single DSI output.
The current CM4IO baseboard DT should work fine on the Raspberry CM4
baseboard and other derivatives baseboards, but proper DT should
be written for other baseboards.

The biggest change is some refactoring of the H616 DRAM driver, which
allows better fine-tuning for each board, and is the base for pending
LPDDR3 and LPDDR4 support, needed by new boards. The sun8i-emac
Ethernet driver sees some refactoring that enables it for the Allwinner
D1 EMAC IP. The sunxi HDMI driver is now using more DT properties. Also
the early SPL code now supports some odd H616 SoC variant.
There are some more patches pending, that require the final review
touches and some testing, I will send a separate PR for them later.
The gitlab CI completed successfully, and I boot tested a few boards
with different SoCs, via FEL and SD card, into Linux.
- DDR Training sequence happens very fast. The speedup in boot time is
negligible by skipping the training sequence during 2nd boot or after.
So remove the check and skip.
- This change improves the robustness of DDR training. If u-boot crashed
during DDR training, the training could be left in a limbo state, where
the BootROM has recorded that it is already in a 2nd boot. The training
must be repeated in this scenario to get out of this limbo state, but due
to the check it cannot be performed.

Add a new config option CONFIG_MVEBU_SPL_SATA_BLKSZ for specifying block
size of SATA disk. This information is used during building of SATA
kwbimage and must be correctly set, otherwise BootROM does not load SPL.

Currently kwboot expected that sector size for SATA image is always 512
bytes. If SATA image cannot be parsed with sector size of 512 bytes, try
larger sector sizes which are power of two and up to the 32 kB. Maximal
theoretical value is 32 kB because ATA IDENTIFY command returns sector size
as 16-bit number.

SATA kwbimage contains offsets in block size unit, not in bytes.
Until now kwbimage expected that SATA disk always have block size of 512
bytes. But there are 4K Native SATA disks with block size of 4096 bytes.
New SATA_BLKSZ command allows to specify different block size than 512
bytes and therefore allows to generate kwbimage for disks with different
block sizes.
This change add support for generating SATA images with different block
size. Also it add support for verifying and dumping such images.
Because block size itself is not stored in SATA kwbimage, image
verification is done by checking every possible block size (it is any
power of two value between 512 and 32 kB).

In the early days of the Allwinner A64 U-Boot support, we relied on a
vendor provided "boot0" binary to perform the DRAM initialisation. This
replaced the SPL, and required to equip the U-Boot (proper) binary with
a vendor specific header to be recognised as a valid boot0 payload.
Fortunately these days are long gone (we gained SPL and DRAM support in
early 2017!), and we never needed to use that hack on any later 64-bit
Allwinner SoC.
Since this is highly obsolete by now, remove that option from the
defconfigs of all A64 boards. We leave the code still in here for now,
since some people expressed their interest in this.

Some SoCs of the H616 family use a die variant, that puts some CPU power
and reset control registers at a different address. There are examples
of two instances of the same board, using different die revisions of the
otherwise same H313 SoC. We need to write to a register in that block
*very* early in the SPL boot, to switch the core to AArch64.
Since the devices are otherwise indistinguishable, let the SPL code read
that die variant and use the respective RVBAR address based on that.
That is a bit tricky, since we need to do that in hand-coded AArch32
machine language, shared by all 64-bit SoCs. To avoid build dependencies
in this mess, we always provide two addresses to choose from, and just
give identical values for all other SoCs. This allows the same code to
run on all 64-bit SoCs, and controls this switch behaviour purely from
Kconfig.

To switch the ARMv8 Allwinner SoCs into the 64-bit AArch64 ISA, we need
to program the 64-bit start code address into an MMIO mapped register
that shadows the architectural RVBAR register.
This address is SoC specific, with just two versions out there so far.
Now a third address emerged, on a *variant* of an existing SoC (H616).
Change the boot0.h start code to make this address a Kconfig
selectable option, to allow easier maintenance.
