sh: Add support for AP-SH4A-4A board
The AP-SH4A-4A board has SH7734, 64MB DDR2-SDRAM, USB, Ethernet, and more. This patch supports the following functions: - 64MB DDR2-SDRAM - 16MB NOR Flash memory - Serial console (SCIF) - Ethernet (SH-Ether with Gigabit) - I2C Signed-off-by: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
