[PATCH 0/3] Rockchip: early boot time optimization

[Sascha Hauer]

On Rockchip boards the ROM loads the barebox binary to the start of DRAM where
later the TF-A is placed, so the first thing all 64bit Rockchip boards do is
to move away from that location. This is done with MMU disabled, so takes some
time. Instead of letting each board repeat this pattern, do the move in atf.c
at a place common for all Rockchip boards and turn on the MMU beforehand.

Also, both TF-A and OP-TEE hold the device tree passed to them in uncached memory,
so accessing it is slow. calling fdt_pack() on the device tree before passing
it squeezes the unused bytes out of the device tree and thus speed up TF-A
and OP-TEE by a few 100ms.

      ARM: rockchip: pack the device tree passed to TF-A and OP-TEE
