From: Johan Jonker Date: Mon, 13 Mar 2023 00:33:23 +0000 (+0100) Subject: include: fdtdec: decouple fdt_addr_t and phys_addr_t size X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=53c5093b2ec08c69b48183e23c5ada3c385053e1;p=u-boot.git include: fdtdec: decouple fdt_addr_t and phys_addr_t size The DT specification supports CPUs with both 32-bit and 64-bit addressing capabilities. In U-boot the fdt_addr_t and phys_addr_t size are coupled by a typedef. The MTD NAND drivers for 32-bit CPU's can describe partitions with a 64-bit reg property. These partitions synced from Linux end up with the wrong offset and sizes when only the lower 32-bit is passed. Decouple the fdt_addr_t and phys_addr_t size as they don't necessary match.
