Raspberry Pi's memory address & size cells are defined in FDT's root node. So, original fdtdec_decode_ram_size() having the cells in memory node will get wrong size cells which misleads memory's reg parsing and have wrong memory banks. This patch provides new decode_ram_size() to parse the memory's reg in FDT for Raspberry Pi 4.
Thanks for your patch. I think what you try to fix is already fixed in v2020.01-rc1 with the following commits: 7a3f15e718 ("dm: Fix default address cells return value") 8076fc298e ("libfdt: Allow #size-cells of 0") 0ba41ce1b7 ("libfdt: return correct value if #size-cells property is not present") ce2dae3a44 ("libfdt: fdt_address_cells() and fdt_size_cells()")
Okay! Thanks for the information. I will try the commits. The v2 patch can be forgot.
Thank you Jian-Hong Pan
