Subject: arm64: zynqmp: Fix r5 mode for cpu release command
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-logo.png?a=commitdiff_plain;h=b872583df10416d437ac18df6ad5c4095806c949;p=u-boot.git

arm64: zynqmp: Fix r5 mode for cpu release command

The cpu release command for r5 mode (lockstep/split) argument
accepts only string. But the zynqmp tcminit command accepts
string or number for r5 mode (lockstep/split or 0/1) argument.
To fix the r5 mode argument, the common argument (lockstep/split
or 0/1) is used across different u-boot commands. Use the strcmp()
instead of strncmp() to make uniform the r5 mode (lockstep/split
or 0/1) for the zynqmp tcminit and cpu release command.
