[U-Boot-Users] Patch to cpu/mpc8260/speed.c
by KokHow Teh 12 Mar '06

Hi; I am using u-boot-1.1.2 and I am sending this minor patch to the cpu/mpc8260/speed.c file in view of MPC8280EC document which lays down how the PCIDF is calculated but not reflected correctly in the file.

[U-Boot-Users] Patch to fix jffs2's lack of "data crc".
by Rick Bronson 12 Mar '06

12 Mar '06

1. A description of the bug: When jffs2 reads files it crc's the header but not the data. If the data is corrupt it can cause jffs2 to accept a chunk when it shouldn't. My patch adds in code to crc the data. 2. A CHANGELOG entry Add crc of data to jffs2 (in jffs2_1pass_build_lists()).

[U-Boot-Users] parser problem?
by Andrew Dyer 12 Mar '06

12 Mar '06

I noticed on my board that if I enter a space and then return at the u-boot command line I get an exception. I using u-boot from cvs and the standard (not hush) parser on a mips platform. Does anybody else see this behaviour? -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] byteorder of image_header_t members?
by Steven Scholz 12 Mar '06

12 Mar '06

Hi there, if uint32_t members of image_header_t are stored in network byteorder, then all references of these members should use ntohl(), right? So should we fix this for instance: #~> grep "\->ih_magic" * cmd_autoscript.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_bootm.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { >>> cmd_bootm.c: if (hdr->ih_magic != IH_MAGIC) { <<< cmd_bootm.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_bootm.c: (ntohl(hdr->ih_magic) != IH_MAGIC)) >>> cmd_doc.c: if (hdr->ih_magic == IH_MAGIC) { <<< >>> cmd_fdc.c: if (hdr->ih_magic != IH_MAGIC) { <<< cmd_fpga.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_ide.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { cmd_nand.c: if (ntohl(hdr->ih_magic) == IH_MAGIC) { cmd_scsi.c: if (ntohl(hdr->ih_magic) == IH_MAGIC) { cmd_usb.c: if (ntohl(hdr->ih_magic) != IH_MAGIC) { -- Steven

[U-Boot-Users] [PATCH] include top config.mk only after CROSS_COMPILE is defined
by Friedrich Lobenstock 12 Mar '06

12 Mar '06

Hi Wolfgang! During compiling I just spotted the fact that gccincdir := $(shell $(CC) -print-file-name=include) in the top config.mk does execute "gcc -print-file-name=include" instead of "m68k-elf-gcc ..." which I would expect as i compile for m68k. I think that this does not make much difference as the includes should mostly be the same, but for the sake of completeness I want to bring the attached patch to your attention. Description of the patch: * CROSS_COMPILE is referenced in the top 'config.mk' file therefore we need to include it in the main Makefile only after CROSS_COMPILE is defined This patch is against the u-boot-1.1.2. -- MfG / Regards Friedrich Lobenstock --- u-boot-1.1.2-org/Makefile 2004-12-19 10:58:11.000000000 +0100 +++ u-boot-1.1.2/Makefile 2005-06-01 18:35:44.000000000 +0200 @@ -46,9 +46,6 @@ # load ARCH, BOARD, and CPU configuration include include/config.mk export ARCH CPU BOARD VENDOR SOC -# load other configuration -include $(TOPDIR)/config.mk - ifndef CROSS_COMPILE ifeq ($(HOSTARCH),ppc) CROSS_COMPILE = @@ -86,6 +83,10 @@ export CROSS_COMPILE +# load other configuration +include $(TOPDIR)/config.mk + + ######################################################################### # U-Boot objects....order is important (i.e. start must be first)

Hi, The following little patch makes the i2c_probe function use reads instead of writes to match the comment (broken in r1.2). * Patch by Peter Korsgaard, 26 May 2005: Use reads instead of writes for probe in soft_i2c. -- Bye, Peter Korsgaard
