Subject: mvebu: image: add check for fdt_add_r and kernel_addr_r variables
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9f0d8826800eef8018720b76b0f4e56fb59b7448;p=openwrt%2Fstaging%2Flinusw.git

mvebu: image: add check for fdt_add_r and kernel_addr_r variables

fdt_addr and kernel_addr variables are getting obsolete in the mainline
u-boot in favor of fdt_addr_r and kernel_addr_r.

By checking if the new variables exist, we can make sure that devices with newer
version of u-boot will work while not breaking support for the existing ones.
