[U-Boot-Users] [PATCH 01/07 v2 ]: General code modification for mpc7448hpc2 board
by Zang Roy-r61911 02 Nov '06

02 Nov '06

General code modification for mpc7448hpc2 board support. 1. Add 7447A and 7448 processor support. 2. Add the following flags. CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically (such as by switch on board), this flag should be set. CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot relocates to RAM, this flag should be set CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the system hang in exception, this flag should be set. There is a design issue for tsi108/109 pci configure read. When pci scan the slots, if there is no pci card, the tsi108/9 will cause a machine check exception for mpc7448 processor.

[U-Boot-Users] mtdparts
by Ladislav Michl 29 Oct '06

29 Oct '06

Hi there. I'm just trying to sync with U-Boot development and found a little regresion in new mtdparts code. Previously I was using custom partition function, which let me do precisely what I wanted. mtd0 - U-Boot mtd1 - env mtd2 - r_env mtd3 - rootfs0 mtd4 - rootfs1 ... etc In above scheme my custom part function allowed only chpart [34], so it was not even possible to change partition to evn sector for example. Moreover it was pretty easy to construct kernel command line this way: setenv bootargs '$bootargs root=/dev/mtdblock$partition ro rootfstype=jffs2' And everything worked nicely. That is no longer case and it's real pain with both NOR and NAND devices used in system. Prefered solution for me is to fix kernel to be able to mount root filesystem from MTD device given by name (root=mtd:rootfs0) unless someone has better idea :-). Something which would work also with 2.4 kernels would be appreciated. ladis

[U-Boot-Users] [PATCH 1/6] AVR32: Use -g instead of -gstabs in AFLAGS_DEBUG
by Haavard Skinnemoen 26 Oct '06

26 Oct '06

In config.mk, -Wa,-gstabs is unconditionally appended to AFLAGS no matter what the target's preferred debugging format is. The AVR32 toolchain doesn't support the stabs debugging format at all, so this will obviously not work. This patch replaces -gstabs with -g when compiling for AVR32, so that the default debugging format is used. Ulf Samuelsson reported problems on ARM when changing this unconditionally, so this patch has been updated to only change AVR32.
