Subject: ARM64: zynqmp: Clear temporary place for storing DDR sizes
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=fd828220df4cec2c192582ef8c02725a0d5768ac;p=thirdparty%2Fu-boot.git

ARM64: zynqmp: Clear temporary place for storing DDR sizes

tmp is placed in BSS section but BSS section is initialized after
relocation but DDR layout needs to be known before relocation that's
why clear temporary place for DDR sizes.
