The current table look-up for the DTB file name turned out bothersome
in terms of maintainability; I ended up adding a new entry every time
a new board is supported.

There is a common pattern between the DT compatible string and the
corresponding file name; drop the vendor prefix "socionext," and
prefix it with "uniphier-" and suffix it with ".dtb".

No need to stop booting U-Boot even if boot mode is unknown.
Setting the "bootmode" environment is only useful for booting

For PH1-LD20 or later, per-pin input-enable control is supported,
that is, we need to set-up IECTRL registers for a group of pins.
This helper function will be useful for a bunch of register settings.

Our own ACPI implementation (when CONFIG_QEMU_ACPI_TABLE is not set)
does not build anymore after x86 has been fully converted to DM PCI.
Instead of trying to fix the build errors, given we now have the ACPI
support via QEMU's fw_cfg interface, which is a more reliable way to
generate correct ACPI tables than by ourselves, hence drop our own
ACPI implementation.

flush_dcache_all() is used in the very end of U-Boot self relocation
to write back all copied and then patched code and data to their
new location in the very end of available memory space.

Since that has nothing to do with IO (i.e. no external DMA happens
here) IOC won't help here and we need to write back data cache contents
manually.

By applying this patch, it will give us some flexibility to expose
a selected partition/s.

e.g:
1. To expose several partitions

2. To expose the all partitions
ums 0 mmc 0:0

3. To expose multiple partititions on several devices
ums 0 mmc 0:1,1:6

    - Run ums to expose only the FAT32 partition - it show the partition
      correctly.

This enables full ethernet usage, including U-Boot to write the board
specific MAC address (ethaddr) into the DT blob before passing it to
Linux.

Without this, the ethaddr is not detected in U-Boot at all, resulting
in this error upon bootup:

The code uses a lot of signed numbers, which ended up in variables
of unsigned type, which resulted in all sorts of underflows. This
in turn caused incorrect calibration on certain boards. Moreover,

Originally, the DLEVEL selects the debug level within the sequencer code,

handling such that for particular debug level, debug messages on that
