Subject: 85xx: Fix detection of MP cpu spin up
X-Git-Tag: v1.3.3-rc1~107^2~2^2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=97b3ecb575a92fa34c1765229dbc06f2b662f139;p=oweals%2Fu-boot.git

85xx: Fix detection of MP cpu spin up

We were looking at the wrong memory offset to determine of a secondary
cpu had been spun up or not.  Also added a warning message if the
all the secondary cpus we expect don't spin up.
