From: Marek Vasut Date: Thu, 7 Sep 2017 07:48:24 +0000 (+0200) Subject: ARM: rmobile: Disable CONFIG_ARCH_FIXUP_FDT_MEMORY X-Git-Tag: v2017.09~17 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=25f840d7ef440442f290e760459714a068487727;p=u-boot ARM: rmobile: Disable CONFIG_ARCH_FIXUP_FDT_MEMORY Disable CONFIG_ARCH_FIXUP_FDT_MEMORY to prevent U-Boot from modifying the memory {} nodes in the DT passed to the Linux kernel. The R8A779x DT contains multiple memory {} nodes, while U-Boot only modifies the first one and stuffs all the memory entries into it, which is wrong. Disabling CONFIG_ARCH_FIXUP_FDT_MEMORY is the least intrusive way to fix the issue this close to the release, while the real fix is to extend the fdt_fixup_memory_banks() to handle multiple memory nodes in DT.
