rockchip: rk3568: Include all addressable DRAM in memory map
Rockchip RK356x supports up to 8 GiB DRAM, however U-Boot only includes
the initial 32-bit 0-4 GiB addressable range in its memory map,
something that matches gd->ram_top and current expected memory available
for use in U-Boot.
The vendor DRAM init blobs add following ddr_mem rk atags [1]:
4 GiB: [0x0, 0xf0000000) and [0x1f0000000, 0x200000000)
8 GiB: [0x0, 0x200000000)
Add the remaining 64-bit 4-8 GiB addressable range, that already is
reported to OS, to the U-Boot memory map to more correctly describe all
available and addressable DRAM of RK356x. While at it also add the
missing UL suffix to the PCIe address range for consistency.
