[PATCH 0/2] Fix sdram size detection on RK3568

[Jonas Karlman]

DRAM initialization blobs for rk356x from vendor encode sdram info in a
new version 3 format. The new format makes use of more bits in sys_reg3
compared to the version 2 format.

This series adds support for decoding basic information from this new
version 3 format. It also adds support for adding a second dram bank of
any usable memory beyond the 4GB mark.

With these patches my Radxa ROCK 3 Model A 2GB correctly report 2GB of
DRAM, instead of 4GB, and my 8GB board can make full use of its memory.

  rockchip: sdram: add basic support for sdram reg info version 3
  rockchip: sdram: add dram bank with usable memory beyond 4GB
