This series is mostly fixes and cleanups for things I found when playing
with EFI support. Most of them I hope are fairly self-explanatory.
What is clearly aimed at running on baremetal is patch #2 ("arm/arm64:
Remove dcache_line_size global variable"), which is needed because the
startup environment is different for EFI apps and we're going to need to do
cache maintenance before setup() is run.
Patch #4 ("lib: arm64: Consolidate register definitions to sysreg.h") is
there to make importing register definitions and other header files from
Linux (like el2_setup.h) easier by switching to the same layout. And arm
is already using sysreg.h for SCTLR fields.
Changes in v2:
* Gathered Reviewed-by tags, thank you!
* For patch #2 ("arm/arm64: Remove dcache_line_size global variable"), I've
modified the commit message to mention the change in parameters for
dcache_by_line_op, I've added the proper header guards to
lib/arm/asm/assembler.h and I've changed raw_dcache_line_size to use ubfx
instead of ubfm.
