Hi Friends, Can I know U-boot has support for MIPS32 24K based platforms? If there is one, I would like to refer that port for our MIPS 24K based platform. Thanks, Joe

[U-Boot] JFFS2 scanning bug
by Mark Jackson 30 Apr '09

30 Apr '09

I've just updated from v2008.10 to v2009.01 on my AVR32 board (MIMC200). JFFS2 no longer works (it hangs at "Scanning JFFS2 FS:", so I've done a git bisect, and here's the result:- 8a36d31f72411144ac0412ee7e1880e801acd754 is first bad commit commit 8a36d31f72411144ac0412ee7e1880e801acd754 Author: Ilya Yanok <yanok(a)emcraft.com> Date: Thu Nov 13 19:49:33 2008 +0300 jffs2: rewrite jffs2 scanning code based on Linux one Rewrites jffs2_1pass_build_lists() function in style of Linux's jffs2_scan_medium() and jffs2_scan_eraseblock().

[U-Boot] [PATCH 0/3][Net][ARM] Davinci Ethernet driver cleanup
by Ben Warren 30 Apr '09

30 Apr '09

Hello, This patch set is an untested attempt at cleaning up the Davinci Ethernet driver. Since I don't have any real hardware, I've tried to keep the logical flow as similar to the original as possible and haven't touched any of the hardware access code. If anybody's able to test it, please do so. Testing consists of 'MAKEALL ARM9' using ELDK 4.1 thanks, Ben

[U-Boot] [PATCH 1/5] ZOOM2 Add initial support for Zoom2
by Tom Rix 30 Apr '09

30 Apr '09

Zoom2 is a new board from Texas Instruments and LogicPD The logicpd web site is a good source for general information on this board. Please start looking here if the below links are broken. http://www.logicpd.com This is a pdf of the product http://www.logicpd.com/sites/default/files/1012659A_Zoom_OMAP34x-II_MDP_Bri… This is the product description web page http://www.logicpd.com/products/development-kits/texas-instruments-zoom%E2%… This patch provides a zoom2 base target by copying zoom1 and by making some obvious changes. To configure, run make omap3_zoom2_config Signed-off-by: Tom Rix <Tom.Rix(a)windriver.com> --- MAINTAINERS | 4 + MAKEALL | 1 + Makefile | 3 + board/omap3/beagle/u-boot.lds | 63 ---------- board/omap3/common/Makefile | 1 + board/omap3/evm/u-boot.lds | 63 ---------- board/omap3/overo/u-boot.lds | 63 ---------- board/omap3/pandora/u-boot.lds | 63 ---------- board/omap3/zoom1/u-boot.lds | 63 ---------- board/omap3/zoom2/Makefile | 49 ++++++++ board/omap3/zoom2/config.mk | 33 +++++ board/omap3/zoom2/zoom2.c | 76 ++++++++++++ board/omap3/zoom2/zoom2.h | 151 +++++++++++++++++++++++ cpu/arm_cortexa8/omap3/config.mk | 2 + cpu/arm_cortexa8/omap3/u-boot.lds | 58 +++++++++ doc/README.omap3 | 13 ++ include/configs/omap3_zoom2.h | 245 +++++++++++++++++++++++++++++++++++++ 17 files changed, 636 insertions(+), 315 deletions(-) delete mode 100644 board/omap3/beagle/u-boot.lds delete mode 100644 board/omap3/evm/u-boot.lds delete mode 100644 board/omap3/overo/u-boot.lds delete mode 100644 board/omap3/pandora/u-boot.lds delete mode 100644 board/omap3/zoom1/u-boot.lds create mode 100644 board/omap3/zoom2/Makefile create mode 100644 board/omap3/zoom2/config.mk create mode 100644 board/omap3/zoom2/zoom2.c create mode 100644 board/omap3/zoom2/zoom2.h create mode 100644 cpu/arm_cortexa8/omap3/u-boot.lds create mode 100644 include/configs/omap3_zoom2.h diff --git a/MAINTAINERS b/MAINTAINERS index 6bb03b4..e19fd0f 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -615,6 +615,10 @@ Stelian Pop <stelian.pop(a)leadtechdesign.com> at91sam9263ek ARM926EJS (AT91SAM9263 SoC) at91sam9rlek ARM926EJS (AT91SAM9RL SoC) +Tom Rix <Tom.Rix(a)windriver.com> + + omap3_zoom2 ARM CORTEX-A8 (OMAP3xx SoC) + Stefan Roese <sr(a)denx.de> ixdpg425 xscale diff --git a/MAKEALL b/MAKEALL index f13c81a..46a96c0 100755 --- a/MAKEALL +++ b/MAKEALL @@ -561,6 +561,7 @@ LIST_ARM_CORTEX_A8=" \ omap3_evm \ omap3_pandora \ omap3_zoom1 \ + omap3_zoom2 \ " ######################################################################### diff --git a/Makefile b/Makefile index c52894c..a9f0d36 100644 --- a/Makefile +++ b/Makefile @@ -2983,6 +2983,9 @@ omap3_pandora_config : unconfig omap3_zoom1_config : unconfig @$(MKCONFIG) $(@:_config=) arm arm_cortexa8 zoom1 omap3 omap3 +omap3_zoom2_config : unconfig + @$(MKCONFIG) $(@:_config=) arm arm_cortexa8 zoom2 omap3 omap3 + ######################################################################### ## XScale Systems ######################################################################### diff --git a/board/omap3/beagle/u-boot.lds b/board/omap3/beagle/u-boot.lds deleted file mode 100644 index 66a8925..0000000 --- a/board/omap3/beagle/u-boot.lds +++ /dev/null @@ -1,63 +0,0 @@ -/* - * January 2004 - Changed to support H4 device - * Copyright (c) 2004 Texas Instruments - * - * (C) Copyright 2002 - * Gary Jennejohn, DENX Software Engineering, <gj(a)denx.de> - * - * 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] [PATCH v3] ARM DaVinci: Adding DM357 Support
by s-paulraj＠ti.com 30 Apr '09

30 Apr '09

Patch adds Support for DaVinci DM357. It boots of a small page NAND on the EVM. The DM357 EVM has 2 NANDs, one small page NAND and another large page NAND. But the device can only boot of the small page NAND. It does not have NOR support. This patch has been tested on the DM357 EVM.

[U-Boot] [RFC] MAKEALL Policy
by Jean-Christophe PLAGNIOL-VILLARD 30 Apr '09

30 Apr '09

Hi all, Actually all the new board or nearly is add to the MAKEALL As point by Kumar it's start to be a huge database I think we need a better policy to add boards in it As it will hard at the end to maintain Personnaly, I'll have in mind to add ref boards or boards that have special drivers or implentation. And stop to duplicate board with the same or near design Best Regards, J.

[U-Boot] U-Boot Timer Qualification
by Jean-Christophe PLAGNIOL-VILLARD 30 Apr '09

30 Apr '09

Hi all, For all Timer modification a minimun of qualification is mandatory as it will impact a lots of part of u-boot. So for this purpose I'll propose you to use one of this two approche to report the precition of your timer or update 1) Clock generation Mesurement Tools needed: Scope or Frequency metter In this approch you will use a gpio to generate a 1Khz and at 1Mhz or it's maximun generated clock frequency before generate one of this clock you will need to known your GPIO and system latency. For this purpose you will generate a clock at your maximum speed as this algo set_gpio_as_output(gpio); while(1) { set_gpio_value(gpio, 1); set_gpio_value(gpio, 0); } after measure the clock (hg_clock) you will it's latency now you will try to generate the 1Khz clock to known the precision of your timer at 1ms while(1) { set_gpio_value(gpio, 1); udelay(1000); set_gpio_value(gpio, 0); } now measure the frequency of the clock the last step is now calculate your precision hg_clock = measured max speed generated clock ms_clock = measured 1Khz generated clock p = (1 / 1000 - (1 / hg_clock + 1 / ms_clock)) * 1000 depending on max generated clock you can known your precision as 1us or less 2) Watch mesurement measured with stop-watch on 100s delay x = measured time p = (100 - x) / 100 Best Regards, J.

[U-Boot] Toradex board with Colibri PXA270
by Daniel Stenberg 29 Apr '09

29 Apr '09

Hello u-booters, I'm currently working with a Toradex board featuring a Colibri PXA270 module, and I noticed this attempt to get a Colibri PXA270 patch applied http://lists.denx.de/pipermail/u-boot/2009-April/050634.html ... which seems it didn't get anywhere further than so. The conclusion, or should I say request, from there was to make more parts re-used within the source tree to reduce code duplication and I can only agree with that. Seeing that this is a PXA(270) equipped board, wouldn't it make sense to do some of the low level init etc stuff in the cpu-specific area (cpu/pxa/) ? The entire gpio handling (and similar) is after all common for all PXA270 isn't it? So, is there anyone with more specific thoughts or opinions on this? What can I do to push this forward to the next level? -- / daniel.haxx.se

[U-Boot] [PATCH v2] ARM DaVinci: Adding DM357 Support
by s-paulraj＠ti.com 29 Apr '09

29 Apr '09

Patch adds Support for DaVinci DM357. This has been tested on a DM357 EVM. It boots of a small page NAND on the EVM. This SOC is very similar to the DM644x. The DM357 EVM has 2 NANDs, one small page NAND and another large page NAND. But the device can only boot of the small page NAND. It does not have NOR support. This patch has been tested on the DM357 EVM.
