Subject: sun7i: Move psci_arch_init close to text_end
X-Git-Tag: v2015.04-rc1~124
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=05c4bd3ec3c99578ee7f1614a546efefc8b362cc;p=oweals%2Fu-boot.git

sun7i: Move psci_arch_init close to text_end

"adr rX, text_end" only works if the label is close. Adding further code
to the other functions will prevent this. So move the containing
function close to label. No functional change.
