4 Subject: [PATCH] MIPS: BCM63XX: sync mips counter during cpu bringup
6 We are using the mips counters as the clock source, so we need to ensure
7 they are synced, else e.g. gettimeofday will return different values
8 depending on which core it was run.
10 Observed difference was about 8 seconds, causing ~8 seconds ping or time
11 running backwards for some programs.
