From: Alexandre Belloni <alexandre.bell...@free-electrons.com>
3.4.108-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 84e871660bebfddb9a62ebd6f19d02536e782f0a upstream.
at91rm9200 standby and suspend to ram has been broken since
00482a4078f4. It is wrongly using AT91_BASE_SYS which is a physical address
and actually doesn't correspond to any register on at91rm9200.
Use the correct at91_ramc_base[0] instead.
Fixes: 00482a4078f4 (ARM: at91: implement the standby function for pm/cpuidle)
