ARM: dts: aspeed: ast2600evb: Use custom flash layout (a45d8872) · Commits · 戴 / test

The AST2600 u-boot and kernel images have outgrown the OpenBMC layout. While BMC machines use 128MB SPI NOR chips, we only have 64MB on the EVB so use a layout that has a smaller region for the ro and rw filesystems. Reviewed-by:
