The UEFI spec mandates that unaligned memory access should be enabled if
supported by the CPU architecture.
This patch implements the function unaligned_access() to set the enable
unaligned data support flag and to clear the aligned flag in the system
control register (SCTLR). It is called when UEFI related commands like
bootefi are invoked.

fatload USB was reported to fail on the Sheevaplug. Debugging showed that
this was caused by an incorrect unaligned write to memory in
path_to_uefi().
UEFI on ARM requires that unaligned memory access is enabled.
* ARMv5 does not support unaligned access at all.
* ARMv6 supports unaligned access when we clear the A flag and set the
U flag.
* On ARMv7 unaligned access is possible when clearing the aligned flag,
which we do in function allow_unaligned() (arch/arm/cpu/armv7/sctlr.S).
For none of the other cpus in arch/arm/cpu/ we have implemented a
similar function.
* ARMv8 allows unaligned access.
Let EFI_LOADER on ARM depend on SYS_CPU=armv7 or SYS_CPU=armv8.
Once we have implemented allow_unaligned() for other ARM CPUs we can add
these to Kconfig.

We shouldn't force which allocator the SPL uses, since there's no

The common SPL removed SoC-specific code for RK3399's SPL and in the
process caused the previously-unconditional DRAM initialization in
board_init_f() to only happen when compiling a configuration that does not
support TPL, meaning DRAM never gets initialized if TPL is supported but
disabled.
Fix this by omitting the DRAM init in SPL only when we are configured to
also build a TPL. This fixes custom configurations that have disabled
TPL, and it should also unbreak the "ficus-rk3399", "rock960-rk3399",
and "chromebook_bob" defconfigs, although since I don't have any of
those devices I can't confirm they're broken now.

The common SPL code reordered the DRAM initialization before
rockchip_stimer_init(), which as far as I can tell causes the RK3399 to
lock up completely.
Fix this issue in the common code by putting the DRAM init back after
timer init. I have only tested this on the RK3399, but it wouldn't make
any sense for the timer init to require DRAM be set up on any system.
