2017-01-22ARM: uniphier: simplify SoC ID get functionMasahiro Yamada
Currently, uniphier_get_soc_type() converts the SoC ID (this is read from the revision register) to an enum symbol to use it for SoC identification. Come to think of it, there is no need for the conversion in the first place. Using the SoC ID from the register as-is a straightforward way.

2016-03-23ARM: uniphier: support Debug UARTMasahiro Yamada
For ARM32 architecture, CONFIG_DEBUG_LL is available for early low-level debugging (and actually UniPhier 32bit SoCs use it), but ARM64 architecture does not support it. Instead, CONFIG_DEBUG_UART is available as an architecture-independent debug facility. This commit supports it on all the UniPhier SoCs (including the new ARMv8 SoCs), which is very useful for new SoC bringups. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
