NeilBrown a63d706ea7 MIPS: ralink: Fix booting on MT7621 ... Since commit 3af5a67c86 ("MIPS: Fix early CM probing") the MT7621 has not been able to boot. This commit caused mips_cm_probe() to be called before mt7621.c::proc_soc_init(). prom_soc_init() has a comment explaining that mips_cm_probe() "wipes out the bootloader config" and means that configuration registers are no longer available. It has some code to re-enable this config. Before this re-enable code is run, the sysc register cannot be read, so when SYSC_REG_CHIP_NAME0 is read, a garbage value is returned and panic() is called. If we move the config-repair code to the top of prom_soc_init(), the registers can be read and boot can proceed. Very occasionally, the first register read after the reconfiguration returns garbage, so add a call to __sync().
