Subject: fsl_law clear enable before changing.
X-Git-Tag: v2009.01-rc1~157^2^2~6
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e1f7d22b8b52fc08c4d17a6a7db1e664281aed63;p=oweals%2Fu-boot.git

fsl_law clear enable before changing.

Debug sessions may have left enabled laws.
Changing lawbar with an unkown enabled tgtid could cause problems.
