Subject: arm: K3: Fix usage of CONFIG_SYS_K3_KEY
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=adc702e22948ec5fe7b6706d0d66ec3bdd35e323;p=u-boot.git

arm: K3: Fix usage of CONFIG_SYS_K3_KEY

For signing the tiboot3.bin image, an optional KEY file can be passed
using CONFIG_SYS_K3_KEY. Right now, Makefile scripts directly takes
the config value and uses it for signing. This is okay if the build
directory is a sub-directory of source tree, otherwise it fails.
Fix it by using the path relative to the source tree.
