powerpc/85xx: Board support for ppa8548
Initial board support for the Prodrive PPA8548 AMC module. Board is an MPC8548 AMC platform used in RapidIO systems. This module is also used to test/work on mainline linux RapidIO software. PPA8548 overview: - 1.3 GHz Freescale PowerQUICC III MPC8548 processor - 1 GB DDR2 @ 266 MHz - 8 MB NOR flash - Serial RapidIO 1.2 - 1 x 10/100/1000 BASE-T front ethernet - 1 x 1000 BASE-BX ethernet on AMC connector Signed-off-by: Stef van Os <stef.van.os@prodrive.nl> Acked-by: Timur Tabi <timur@tabi.org> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>hifive-unleashed-5.1
