[U-Boot] [PATCH V7 1/3] Initial support for Marvell Orion5x SoC
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 get_ram_size(). V5: Replaced macros by C structs in dram code. Removed compilation warnings in dram code. Added comments to legacy flash definitions. Split low level init code into SoC- and Chip-specifics. V6: Set copyright dates to 2010, and put standard GPL notice mentioning Marvell's copyright on *_lowlevel_init.S files. V7: Moved GPIO and MPP init code in SoC arch_misc_init() in C. lowlevel_init.S now only contains DRAM init code.
Patch 1 checkpatched with 0 errors and 1 spurious warning. Patches 2 and 3 checkpatched with 0 errors and 0 warnings.

Hi Albert
I am OOO for next four days, I will try to provide feedback earliest possible

-----Original Message----- From: u-boot-bounces@lists.denx.de [mailto:u-boot-bounces@lists.denx.de] On Behalf Of Albert Aribaud Sent: Thursday, June 10, 2010 2:20 AM To: u-boot@lists.denx.de Subject: [U-Boot] [PATCH V7 1/3] Initial support for Marvell Orion5x SoC
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 get_ram_size(). V5: Replaced macros by C structs in dram code. Removed compilation warnings in dram code. Added comments to legacy flash definitions. Split low level init code into SoC- and Chip-specifics. V6: Set copyright dates to 2010, and put standard GPL notice mentioning Marvell's copyright on *_lowlevel_init.S files. V7: Moved GPIO and MPP init code in SoC arch_misc_init() in C. lowlevel_init.S now only contains DRAM init code.
Patch 1 checkpatched with 0 errors and 1 spurious warning. Patches 2 and 3 checkpatched with 0 errors and 0 warnings.
