* [U-Boot] [PATCH V3 1/3] Initial support for Marvell Orion5x SoC @ 2009-12-01 20:27 Albert Aribaud 2009-12-01 20:27 ` [U-Boot] [PATCH V3 2/3] Add Orion5x support to 16550 device driver Albert Aribaud 2009-12-23 9:27 ` [U-Boot] [PATCH V3 1/3] Initial support for Marvell Orion5x SoC Prafulla Wadaskar 0 siblings, 2 replies; 6+ messages in thread From: Albert Aribaud @ 2009-12-01 20:27 UTC (permalink / raw) To: u-boot 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> --- V1 of the patch was monolithic V2 contains a number of fixes as a result of the V1 review, and notably: - is split in three patches : orion, serial, edmini; - has been checkpatch'ed, with only 6 errors, in patch 1/3, all 6 errors being false positives. V3 contains yet several fixes as a result of the V2 review, and notably: - removes most of the GPIO and MPP programming support; - adds low level init and removes CONFIG_SKIP_LOW_LEVEL_INIT. cpu/arm926ejs/orion5x/Makefile | 51 ++++++ cpu/arm926ejs/orion5x/cpu.c | 258 ++++++++++++++++++++++++++++++ cpu/arm926ejs/orion5x/dram.c | 61 +++++++ cpu/arm926ejs/orion5x/timer.c | 181 +++++++++++++++++++++ include/asm-arm/arch-orion5x/cpu.h | 205 ++++++++++++++++++++++++ include/asm-arm/arch-orion5x/mv88f5182.h | 40 +++++ include/asm-arm/arch-orion5x/orion5x.h | 65 ++++++++ 7 files changed, 861 insertions(+), 0 deletions(-) create mode 100644 cpu/arm926ejs/orion5x/Makefile create mode 100644 cpu/arm926ejs/orion5x/cpu.c create mode 100644 cpu/arm926ejs/orion5x/dram.c create mode 100644 cpu/arm926ejs/orion5x/timer.c create mode 100644 include/asm-arm/arch-orion5x/cpu.h create mode 100644 include/asm-arm/arch-orion5x/mv88f5182.h create mode 100644 include/asm-arm/arch-orion5x/orion5x.h diff --git a/cpu/arm926ejs/orion5x/Makefile b/cpu/arm926ejs/orion5x/Makefile new file mode 100644 index 0000000..5386379 --- /dev/null +++ b/cpu/arm926ejs/orion5x/Makefile @@ -0,0 +1,51 @@ +# +# Copyright (C) 2009 Albert ARIBAUD <albrt.aribaud@free.fr> +# +# Based on original Kirkwood support which is +# (C) Copyright 2009 +# Marvell Semiconductor <www.marvell.com> +# Written-by: Prafulla Wadaskar <prafulla@marvell.com> +# +# See file CREDITS for list of people who contributed to this +# project. +# +# This program is free software; you can redistribute it and/or +# modify it under the terms of the GNU General Public License as +# published by the Free Software Foundation; either version 2 of +# the License, or (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

All of the V2 isses have disappeared with dropping the files in V3, but this one crept in just to keep the good-vs-evil balance. Historically, this file was built by extracting the necessary code from several files in the Marvell LSP provided with the ED Mini on LaCie's website. However, it was then rewritten to eliminate all macros and now, while it does execute the same low level initializations as the originals did, it does so with its own set of instructions and with all generic execution paths removed. That being said, it might still be considered derived work, and if considered derived, publishing this under 'GPLv2 or later' would require formal approval from the copyright owner. Prafulla, you're as close a copyright owner for this original code as I could find on this list. Does Marvell consider this file I'm submitting as derived work, and if it does, does it allow publishing it under GPLv2 or later? Amicalement, -- Albert. ^ permalink raw reply [flat|nested] 6+ messages in thread
