[U-Boot] [PATCH] UBI: Fix build problem noticed on Apollon (arm/testing repo)
by Stefan Roese 07 Jul '09

07 Jul '09

This patch fixes a build problem noticed on Apollon by using mtd_dev_by_eb() instead of "/" as done in the Linux UBI version. So this brings the U-Boot UBI version more in sync with the Linux version again.

[U-Boot] Need assistance with increasing command line size on Cavium
by Garrett Cooper 06 Jul '09

06 Jul '09

Hello, Our group is running into command line length issues with a number of Cavium boards we have at our office (CN38xx, CN5xxx), and I was wondering (apart from the Linux kernel command line length), where I would look to increase the size for the command line that's passed from U-boot to the Linux kernel, as well as maybe which config file I should be modifying to enact these changes. Thanks, -Garrett

[U-Boot] [U-BOOT] cfi_flash.c fails to program NOR Flash SST39LF040
by Po-Yu Chuang 06 Jul '09

06 Jul '09

Hello, I have a board on which there is a NOR Flash SST39LF040. Previously, I copied flash.c from other boards. Now I am trying to migrate NOR Flash driver to use CFI, but it fails to program sectors which are not on the 0x10000 boundaries. I found that in function flash_write_cfiword() @drivers/mtd/cfi_flash.c it issues command with address relative to sector address. However, according to SST39 series data sheet, it seems that we should issue command with address relative to flash base address? After I modified flash_write_cfiword() to issue command to sector 0, everything works fine. Is it a bug?

[U-Boot] [PATCH] at91sam9260/9263: add back up fot the rst(reset controller).
by Sedji Gaouaou 05 Jul '09

05 Jul '09

On the boards at91sam9260ek, at91sam9263ek and afed9260, the rstc register was set to 0 after being set to 500 ms for the PHY reset. Do backup the old reset length and restore it after the MACB initialisation.

[U-Boot] [PATCH-ARM] CONFIG_SYS_HZ fix for ARM920T S3C24X0 Boards
by kevin.morfitt＠fearnside-systems.co.uk 05 Jul '09

05 Jul '09

This sets CONFIG_SYS_HZ to 1000 for all boards that use the s3c2400 and s3c2410 cpu's. Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for thge SBC2440-II Board. Also, ran MAKEALL for all ARM9 targets and no new warnings or errors were found. Note that the existing code modified by this patch does not meet the u-boot coding style but I'd like to handle this separately and submit patches to fix this later.

[U-Boot] U-Boot][PATCH] ARM Clean-up of ARM920T S3C24x0 drivers code
by kevin.morfitt＠fearnside-systems.co.uk 04 Jul '09

04 Jul '09

This re-formats the S3C24x0 drivers code to meet the coding style requirements and to make it always use the proper I/O accessor functions when accessing registers. It was done using 'Lindent -kr -i8 -l80' followed by manual inspection of the output. checkpatch.pl reports no problems with the patch and I've run MAKEALL for all ARM9 boards with no problems. This has been done to create a good starting point for me to add support for a new board, the Embest SBC2440-II. Another patch does the same for the ARM920 S3C24x0 CPU and headers code.

[U-Boot] [PATCH 0/4 v2] Clean up the Nomadik board and add OneNand
by Alessandro Rubini 02 Jul '09

02 Jul '09

This patch-set cleans up some glitches in my first submission. I posted it as a single patch and a separate timer patch. The first one is split as JC asked, and the timer patch is there as well since it is conceptually in the same set, although I had no comments on the timer part yet. JC: I didn't split "clean" and "onenand", since the change in partitioning information in the config file is part of introducing onenand. A split would have introduced a never-tested artificial middle version.
