v3: Fixed problem with CFG vs CONFIG_SYS in board/ads5121/ads5121.c v2: Reworked MPC5121 NAND driver. Attempted to address all the problems listed by Scott Wood. Driver is now board independent. Will still need more work to be SOC independent. Driver for the NAND controller on MPC5121. This driver has been tested on ADS5121 rev4 / MPC5121e rev2 only which has the following configuration: 2K page size 8 bit device width This should work on other boards with MPC5121 rev2 silicon with little or no change to the driver. Various vintages of this controller exist on some iMX parts. Getting it to work on an iMX with the same controller version should be fairly easy. More work if it is an iMX with a different version on the controller. This controller treats 2K pages as 4 512 byte pages and the hw ecc is over the combined 512 byte main area and the first 7 bytes of the spare area. The hw ecc is stored in the last 9 bytes of the spare area. This all means the the spare area can not be written separately from the main. This means unmodified JFFS2 will not work.

[U-Boot-Users] Add a new command to U-Boot
by Carlos Filipe Silva 20 May '09

20 May '09

Hi all! I have one doubt. How can I add a new command to U-Boot? Do I have to use only the macro U_BOOT_CMD() like files .../common/cmd_* or do I have to do more things, like defines, etc.? And after this is compliled with no error, if I type help in U-Boot's shell, do I see this command like the others? Best regards, Carlos Silva

[U-Boot] Using U-boot on the IXP432
by David Milway 02 May '09

02 May '09

Hi, I have been using a board with and IXP432 for about a year now, starting with Redboot but running in big endian mode. I am now looking at using u-boot for network booting but I would like to run it in little endian mode. Before I get stuck into to porting the code I have a few questions. 1) Has anybody else ported the code to the IXP432? 2) Is there any reason that the IXP cpu configuration sets the bigendian flag and should it be possible just to set it to little endian and will the bulk of the code work without modification? Thanks Dave

[U-Boot] Xilinx LL-TEMAC driver
by monstr＠monstr.eu 06 Apr '09

06 Apr '09

Hi Ben and Wolfgang, first patch just sort labels in drivers/net/Makefile I think this patch could be applied directly to Wolfgang tree. The second patch is Xilinx LL Temac driver. This driver was sent to mailing list some month ago by Yoshio Kashiwagi. I clean the driver and add support for Fifo mode. This driver is tested on some Microblaze boards. There is one part which should be rework in future. (FIXME comment) It is about PHY lib which we discussed in past. I believe that this part won't be a problem. Thanks for your comments, Michal

[U-Boot] [PATCH] IXP425: Add new IXP425 board emPC-A400 Part 2/2
by Stefan Althoefer 03 Apr '09

03 Apr '09

[PATCH] IXP425: Add new IXP425 board emPC-A400 This patch adds support for the emPC-A400 CPU board from Janz Automationssysteme. It will also apply to some of the Janz emVIEW displays which are based on this CPU board. Besides of the board support, the patch includes two features which are (up to now) private to this port but might be of interrest to others. 1. Ability to download microcode to the NPE unit. This code works without using the Intel Library (which makes it smaller). This is good if you do not want to do networking in u-boot, but want boot an NFS-rooted linux system (where linux cannot load the microcode by itself). Refer to boards/empca400/cmd_npe.c 2. Ability to boot the IXP425 Windows-CE kernel. Refer to boards/empca400/cmd_bootce.c. The patch is against "latest" u-boot git-repository Please (still) be patient if style of submission or patches are offending.
