[PATCH v2 0/6] ARM: Rockchip: Read amount of memory from DDR controller

[Sascha Hauer]

This series adds support for reading the amount of memory from
the DDR controller. This helps on boards which come with
different amounts of memory like the Radxa Rock3a.

This series also fixes issues with an upstream TF-A firmware. With this
the IRAM where the bootsource is stored is no longer accessible in
normal mode. We have to read its contents before starting the TF-A.
For this it became necessary to add a common barebox entry function
for rk3568, to get a common place to read the IRAM contents.

Sascha

Changes since v1:
- Call relocate_to_adr_full() from board code to make sure the
  fdt from the relocated binary is used, not from the original
  binary
- Add patch to pass a NULL fdt to TF-A
