[V2 PATCH 0/2] Update RAM Bank Logic for RK3568/RK3588

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

Use the ATAG info provided by the Rockchip binary TPL to identify
RAM banks on the RK3568 and RK3588 when using the ROCKCHIP_TPL binary.

This is needed because there are specific addresses that should not
be written to for all RK3588 based devices with >=16GB of RAM, writing
to these addresses immediately results in a crash. Additionally on the
RK3568 and RK3588 this allows us to reclaim 256MB of RAM when RAM >=
4GB.

Changes since V1:
 - After additional feedback, removed RFC tag.
 - Made code work for both RK3568 and RK3588.
 - Removed memory hole code for all RK3588 boards.
 - Updated CONFIG_NR_DRAM_BANKS for 3568 and 3588 boards as it is
   the max number of banks supported by the ATAGS code.

  rockchip: sdram: Support getting banks from TPL for rk3568 and rk3588
  rockchip: Switch RK3568 and RK3588 to new RAM bank logic
