Masahiro Yamada	4e3d84066e	ARM: uniphier: use (devm_)ioremap() instead of map_sysmem() ... This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>	2016-07-24 00:13:10 +09:00
Masahiro Yamada	9c2f9b2da6	ARM: uniphier: insert dsb barrier to ensure visibility of store ... I noticed secondary CPUs sometimes fail to wake up, and the root cause is that the sev instruction wakes up slave CPUs before the preceding the register write is observed by them. The read-back of the accessed register does not guarantee the order. In order to ensure the order between the register write and the sev instruction, a dsb instruction should be executed prior to the sev.
