-Subject: [PATCH] rockchip: Fix u-boot-rockchip.bin build
-
-Currently there are a few arm32 rockchip board configs that don't generate
-u-boot-rockchip.bin when running make because CONFIG_BINMAN is not enabled.
-This patch changes CONFIG_ARCH_ROCKCHIP to also select CONFIG_BINMAN if
-CONFIG_SPL and !CONFIG_ARM64.
-
-Example builds that don't generate u-boot-rockchip.bin without this patch:
-
-export ARCH=arm
-export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
-make kylin-rk3036_defconfig
-make
-
-export ARCH=arm
-export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
-make rock_defconfig
-make
-
-export ARCH=arm
-export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf-
-make tinker-rk3288_defconfig
-make
