[U-Boot-Users] [PATCH] Use info->reset_cmd instead of FLASH_CMD_RESET
by Zachary Landau 25 Sep '05

25 Sep '05

Hello, This patch makes cfi_flash.c use info->cmd_reset. It was being set by flash_get_size() but not being used, which kept the Flash on my board from properly being reset. It looks like there are a lot of switch cases for different flash types that could probably probably be removed by setting up some function pointers, but that is a project for another time. -- Zachary P.

[U-Boot-Users] [patch] fix lib_generic version of strswab()
by Andrew Dyer 25 Sep '05

25 Sep '05

This patch changes the behavior of strswab() to end the byte swapping when either of the two candidate bytes is null. The old behavior was to only abort when the second byte was null. It looks like this is only used for little endian machines running with CONFIG_IDE. I noticed this because the ide serial number was not printing out - the reason was strswab() was running past the end of the previous string in memory and swapping a null into the first byte of my serial number string. -- Hardware, n.: The parts of a computer system that can be kicked.

[U-Boot-Users] Patch: Typos in include/ppc440.h
by Andrew E Mileski 25 Sep '05

This is in CVS as well as u-boot-1.1.2.tar.bz2 and as far back as at least u-boot-0.2.0.tar.bz2 File: include/ppc440.h Line:235 Context: #define pbear 0x20 /* periph bus error addr reg */ #define pbesr 0x21 /* periph bus error status reg */ #define xbcfg 0x23 /* external bus configuration reg */ #define xbcid 0x23 /* external bus core id reg */ ^^^^ According to the 440GX user manual (mine's dated Nov 21, 2003) table 4-13 on page 186, EBC0_CID the "EBCO Peripheral Core ID Register" is located at offset 0x24. This register is not currently referenced by any code in the u-boot-1.1.2.tar.bz2 release, which explains why it has survied so long. Also note that the header comment for this section has a typo, which is also corrected in the attached patch. -- Andrew E.

[U-Boot-Users] [patch] tools/bmp_logo.c using incorrect offset to pixel data
by Andrew Dyer 25 Sep '05

25 Sep '05

The attached patch makes bmp_logo.c use the header information about the start of pixel data in the bmp file instead of trying to find the start itself. If someone wants a test case bmp file that will produce incorrect output with the current code e-mail me and I can send it along. The bug was seen with the tool compiled/running under redhat 7.3 on x86 arch. The visual indication was that the bitmap was shifted to the right with a section of garbage displayed in the lower left corner. The source bmp displays fine with Win2000. I would suggest it's worth noting in the somewhere in docs that include/bmp_logo.h is overwritten by the default build environment (with the Denx logo :-( ). I added a line like this to my board config.mk file to override this behavior. #logo bitmap LOGO_BMP = ../board/eldorado/rht_small_logo.bmp -- Hardware, n.: The parts of a computer system that can be kicked.
