[PATCH v3 0/3] rockchip: sdram: Fix issues observed on RK3576

[Jonas Karlman]

Most Rockchip AArch64 SoCs have start of DRAM at 0x0. However, the
RK3576 instead has start of DRAM at 0x40000000 and can extend continuous
beyond the 4 GiB mark.

This series fixes issues observed on a Rockchip RK3576 board testing
Heiko's RK3576 series [1].

Changes in v3:
- Fix 32-bit overflow limiting usable ram_top to max 4G

Changes in v2:
- Drop duplicate patch
- Add patch to limit gd->ram_top to max 4G
- Add patch to assign gd->ram_base in SPL
- Collect r-b tag
