Subject: arm64: zynqmp: Use minimal size for environment variables
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5a6e3759d975e09a3542d8b72b1b6f6a3802e542;p=thirdparty%2Fu-boot.git

arm64: zynqmp: Use minimal size for environment variables

There is no reason to have huge space for variables because none is
using that. But there are some which are setup automatically.

baudrate=115200
fdtcontroladdr=ffffa0d0
stderr=dcc
stdin=dcc
stdout=dcc

Environment size: 72/124 bytes
