[U-Boot] [PATCH V7 1/3] Initial support for Marvell Orion5x SoC
by Albert Aribaud 14 Jun '10

14 Jun '10

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(a)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. arch/arm/cpu/arm926ejs/orion5x/Makefile | 55 +++++ arch/arm/cpu/arm926ejs/orion5x/cpu.c | 271 ++++++++++++++++++++++ arch/arm/cpu/arm926ejs/orion5x/dram.c | 64 +++++ arch/arm/cpu/arm926ejs/orion5x/lowlevel_init.S | 293 ++++++++++++++++++++++++ arch/arm/cpu/arm926ejs/orion5x/timer.c | 181 +++++++++++++++ arch/arm/include/asm/arch-orion5x/cpu.h | 203 ++++++++++++++++ arch/arm/include/asm/arch-orion5x/mv88f5182.h | 40 ++++ arch/arm/include/asm/arch-orion5x/orion5x.h | 69 ++++++ 8 files changed, 1176 insertions(+), 0 deletions(-) create mode 100644 arch/arm/cpu/arm926ejs/orion5x/Makefile create mode 100644 arch/arm/cpu/arm926ejs/orion5x/cpu.c create mode 100644 arch/arm/cpu/arm926ejs/orion5x/dram.c create mode 100644 arch/arm/cpu/arm926ejs/orion5x/lowlevel_init.S create mode 100644 arch/arm/cpu/arm926ejs/orion5x/timer.c create mode 100644 arch/arm/include/asm/arch-orion5x/cpu.h create mode 100644 arch/arm/include/asm/arch-orion5x/mv88f5182.h create mode 100644 arch/arm/include/asm/arch-orion5x/orion5x.h diff --git a/arch/arm/cpu/arm926ejs/orion5x/Makefile b/arch/arm/cpu/arm926ejs/orion5x/Makefile new file mode 100644 index 0000000..11f4141 --- /dev/null +++ b/arch/arm/cpu/arm926ejs/orion5x/Makefile @@ -0,0 +1,55 @@ +# +# Copyright (C) 2010 Albert ARIBAUD <albert.aribaud(a)free.fr> +# +# Based on original Kirkwood support which is +# (C) Copyright 2009 +# Marvell Semiconductor <www.marvell.com> +# Written-by: Prafulla Wadaskar <prafulla(a)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.

[U-Boot] [STATUS] v2010.06-rc2 is out
by Wolfgang Denk 13 Jun '10

13 Jun '10

Hello, I have just released v2010.06-rc2. Unfortunately, there is still no new ARM stuff included, as I'm still waiting for respective pull requests. Eventually we will have to delay the release because of that. A "next" branch has been created, which now contains the Makefile simplification patches. I guess most pending patches for the next release need to be rebased against this. Please note that all submissions for new boards should ONLY require an entry to boards.cfg; patches that try to add any complex rules to the top level makefile will probably be rejected because of that. Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de Some programming languages manage to absorb change, but withstand progress. -- Epigrams in Programming, ACM SIGPLAN Sept. 1982

[U-Boot] [PATCH 0/3] Makefile: rework / cleanup
by Wolfgang Denk 13 Jun '10

13 Jun '10

The top level Makefile is growing and growing. Once, wehn we suppoted only a few tens of boards, it was possible to implement board configuration logic in the Makefile, but it quickly turned out that this doesn't scale. Also, it is not really needed (at least not any more) - we noch have mechanisnms in place, that allow for more efficient code. The following patch series is an attempt to start some cleanup and reduce the size of the top level Makefile. The solution is neither perfect nor complete - there are quite a lot of boards that resist such a cleanup and need more thorough cleanup. But it's an initial step, showing what could and should be done, which boards have problems, and why this is the case. Eentually this paves the ground for a more friendly way to add new board configurations. 1/3: Fix printing of make targets, simplify Makefile Makefile | 740 ++++++++++++++++++++----------------------------------------- 1 files changed, 243 insertions(+), 497 deletions(-) 2/3: Makefile: simplify handling of build target names Makefile | 774 ++++++++++++++++++++++++++++++-------------------------------- mkconfig | 4 +- 2 files changed, 379 insertions(+), 399 deletions(-) 3/3: Makefile: simplify handling of common board configurations Makefile | 1436 ++++++++++++++++++++++++++------------------------------------ 1 files changed, 607 insertions(+), 829 deletions(-)
