Most EFI implementations use 64-bit. Add a way to build U-Boot as a 64-bit
EFI payload. The payload unpacks a (32-bit) U-Boot and starts it. This can
be enabled for x86 boards at present.

It is useful to be able to load U-Boot onto a board even if is it already
running EFI. This can allow access to the U-Boot command interface, flexible
booting options and easier development.
The easiest way to do this is to build U-Boot as a binary blob and have an
EFI stub copy it into RAM. Add support for this feature, targeting 32-bit
initially.
Also add a way to detect when U-Boot has been loaded via a stub. This goes
in common.h since it needs to be widely available so that we avoid redoing
initialisation that should be skipped.

With EFI the start address of U-Boot is specified differently. We could
consider just setting GD_FLG_RELOC and then setting up reloc_off. But that
flag has other implementations and we are not able to use U-Boot relocation
which this flag implies.
Instead, just add a special case for EFI.

When running as an EFI application, U-Boot must request memory from EFI,
and provide access to the boot services U-Boot needs.
Add library code to perform these tasks. This includes efi_main() which is
the entry point from EFI. U-Boot is built as a shared library.

Currently, kzalloc() returns zero-filled memory, while kmalloc()
simply ignores the second argument and never fills the memory
area with zeros.
I want kmalloc(size, __GFP_ZERO) to behave as kzalloc() does,
which will make it easier to add more memory allocator variants.
With the introduction of __GFP_ZERO flag, going forward, kzmalloc()
variants can fall back to kmalloc() enabling the __GFP_ZERO flag.

Property names are stored in a string table. When a node property is
removed, the string table is not updated since other nodes may have a
property with the same name.
Thus it is possible for the string table to build up a number of unused
strings. Add a function to remove these. This works by building a new device
tree from the old one, adding strings one by one as needed.

Drystone provides a convenient sanity check that the CPU is running at full

Currently, this function returns a positive value on error,
so we never know whether this function has succeeded or failed.
For example, if the given property is not found, fdt_getprop()
returns -FDT_ERR_NOTFOUND, and then this function inverts it,
i.e., returns FDT_ERR_NOTFOUND (=1).

Move common functions from cmd_nand.c (for calculating offset
and size from cmdline paramter) to common place, so they could
used from other commands which use mtd partitions.
For onenand the arg_off_size() is left in common/cmd_onenand.c.
It should use now the common arg_off() function, but as I could
not test onenand I let it there ...

Commit 9ba9e85f3f1c (net: Fix NET_RANDOM_ETHADDR dependencies)
accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards.
Prior to that commit, those boards defined CONFIG_LIB_RAND, but not
CONFIG_NET_RANDOM_ETHADDR. So, commit 9ba9e85f3f1c should not have
touched them, but in fact it ripped CONFIG_LIB_RAND off from all the
header files, which caused undefined reference to srand and rand.
CONFIG_LIB_RAND=y must be revived for such boards.
BTW, this commit indeed makes it better, but even with this fix,
three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not
build due to region 'ram' overflowed error. This was cause by
commit 6eed3786c68c (net: Move the CMD_NET config to defconfigs)
because CMD_NET selects NET, and NET selects REGEX. Eventually,
some boards were newly enabled with CONFIG_REGEX, increasing the
memory footprint. A patch is expected to fix the build error.

PIRQ routing is pretty much common in Intel chipset. It has several
PIRQ links (normally 8) and corresponding registers (either in PCI
configuration space or memory-mapped IBASE) to configure the legacy
8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing
support using device tree and move it to a common place, so that we
can easily add PIRQ routing support on a new platform.

After syncing the sunxi dts files with the upstream kernel dm/fdt sunxi
builds would no longer boot.
The problem is that stdout-path is now set like this in the upstream dts
files: stdout-path = "serial0:115200n8". The use of options in of-paths,
either after an alias name, or after a full path, e.g. stdout-path =
"/soc@01c00000/serial@01c28000:115200", is standard of usage, but something
which the u-boot dts code so far did not handle.
This commit fixes this, adding support for both path formats.

The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.
For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.
