Build an SPL which can be started via SCIF download mode on R-Car Gen3
and allows loading and executing U-Boot uImage with the next stage code.
This is also useful for starting e.g. ATF BL2, which inits the hardware
and returns to the U-Boot SPL, which can then load e.g. U-Boot proper.
The H3, M3-W, M3-N SoCs have plenty of SRAM for storing the U-Boot SPL
while the payload, e.g. ATF BL2, executes, so there is no problem here.
However, E3 and D3 have much less SRAM, hence the loader uses a trick
where it copies itself beyond the area used by BL2 and executes from
there. That area is 32kiB large and not enough to hold U-Boot SPL, BSS,
stack and malloc area, so the later two are placed at +0x4000 offset
from start of SRAM, another area not used by ATF BL2. To make things
even more complicated, the SCIF loader cannot load to the upper 32kiB
of the SRAM directly, hence the copying approach.

Enable LZO compression of the multi-DTB fitImages, since the U-Boot
with multiple DTs enabled is becoming quite large and the DTs can
be well compressed. The LZO compression saves almost 200 kiB on the

Disable CONFIG_ARCH_FIXUP_FDT_MEMORY to prevent U-Boot from modifying
the memory {} nodes in the DT passed to the Linux kernel. The R8A779x
DT contains multiple memory {} nodes, while U-Boot only modifies the
first one and stuffs all the memory entries into it, which is wrong.
Disabling CONFIG_ARCH_FIXUP_FDT_MEMORY is the least intrusive way to
fix the issue this close to the release, while the real fix is to
extend the fdt_fixup_memory_banks() to handle multiple memory nodes
in DT.

At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).
Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.
Also expand the help for the 'nowhere' option and move it to the top since
it is the default.
