Subject: ARM64: zynqmp: Add prog_reg to xil_io.h
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fcc68028371738247b197c3d73b255cb311a90ec;p=thirdparty%2Fu-boot.git

ARM64: zynqmp: Add prog_reg to xil_io.h

Vivado is not putting this function to psu_init.c
file that's why this function is missing is some versions.
Make this function as weak to make sure that compilation is fine.
