This patch adds support for the Marvell Orion5x SoC. It has no use alone, and must be followed by a patch to add Orion5x support for serial, then support for the ED Mini V2, an Orion5x-based product from LaCie.
Signed-off-by: Albert Aribaud albert.aribaud@free.fr --- Patchset history
V1: Initial monolithic patch. V2: split in three patches : orion, serial, edmini; checkpatch'ed, with only 6 errors, in patch 1/3, all 6 errors being false positives. V3: useless GPIO and MPP programming support removed; low level init added/CONFIG_SKIP_LOW_LEVEL_INIT removed. V4: all files licensed GPLv2-only removed; RAM bank size detection now uses getm_ram_size().
