Subject: layerscape: define IMAGE_SIZE and LS_SYSUPGRADE_IMAGE_SIZE
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2a5460b11b9718ed5f398fcc381edc89bce72695;p=openwrt%2Fstaging%2Fxback.git

layerscape: define IMAGE_SIZE and LS_SYSUPGRADE_IMAGE_SIZE

Define 64m IMAGE_SIZE for flash firmware.bin since the flash size
is 64MB. Define 48m LS_SYSUPGRADE_IMAGE_SIZE for flash sysupgrade.bin
which contains maximum 16MB kernel and 32MB rootfs according to
memory map.
