ARM: uniphier: move PLL init code to U-Boot proper where possible The PLL for the DRAM interface must be initialized in SPL, but the others can be delayed until U-Boot proper. Move them from SPL to U-Boot proper to save the precious SPL memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> 2016-09-16 18:33:09 +00:00			`/*`
