armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kernel Disable D-Cache is required when booting nommu Linux kernel. (please see Linux kernel source "arch/arm/kernel/head-nommu.S") U-Boot is enabled D-cache and I-Cache at startup. However, it does not disable D-Cache before booting nommu Linux kernel. Therefore, I call dcache_disable() when the CPU is ARMv7M to fix this problem. Signed-off-by: Toshifumi NISHINAGA <tnishinaga.dev@gmail.com>
