2016-07-23ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()Masahiro Yamada
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>
2016-07-15armv8: mmu: Add support of non-identical mappingYork Sun
Introduce virtual and physical addresses in the mapping table. This change have no impact on existing boards because they all use idential mapping. Signed-off-by: York Sun <york.sun@nxp.com>
2016-06-08ARM: uniphier: insert dsb barrier to ensure visibility of storeMasahiro Yamada
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. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
