[U-Boot] [PATCH 02/21] ARM: uniphier: rework struct uniphier_board_data

Masahiro Yamada yamada.masahiro at socionext.com
Fri Feb 26 06:21:34 CET 2016


This commit reworks "struct uniphier_board_data" with an array of
DRAM channel data in it.  It will allow further cleanups by means of
"for" statements that iterate over the DDR channels.
