mkelfImage & newer kernels
by Troy Telford 06 Oct '10

06 Oct '10

This applies to 2.6.31 & 2.6.32 kernels for certain, but probably other newer kernels as well. I'm a user of mkelfImage; I am currently unable to get an .ebi generated by mkelfImage to boot properly - I can't load it directly, or via a mechanism like kexec. The moment the command (be it etherboot/gpxe, or kexec) tries to load the kernel, the system immediately reboots. If I directly kexec a kernel (minus mkelfImage), the kernel loads correctly, so it appears the problem is in mkelfImage. Unfortunately, I don't know how to fix it, and I _have_ to use mkelfImage to generate .ebi images for my systems. I've tried 2.6.27, 2.6.31, 2.6.32; of those, 2.6.27 (and older kernels, work fine. 2.6.31 & 32 results in an .ebi that causes the system to reboot. Any help!? Thanks, Troy Telford

#163: Board still requires RAMBASE <1MB

#163: Board still requires RAMBASE <1MB -------------------------+-------------------------------------------------- Reporter: oxygene | Owner: stepan@… Type: defect | Status: new Priority: minor | Milestone: Component: coreboot | Keywords: Dependencies: | Patchstatus: there is no patch -------------------------+-------------------------------------------------- Some boards have RAMBASE at 0x4000. For some, it's probably a left-over from old times, but others actually require it. Update the former, and fix the latter. Wyse/s50 requires 0x4000, see http://www.coreboot.org/pipermail/coreboot/2010-May/058080.html (and the log file therein) -- Ticket URL: <https://tracker.coreboot.org/trac/coreboot/ticket/163> coreboot <http://www.coreboot.org/>

#110: Allow for per-device subsystem IDs

#110: Allow for per-device subsystem IDs ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: enhancement | Status: new Priority: minor | Milestone: Component: coreboot | Version: v3 Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ Currently both v2 and v3 only allow us to use one global set of PCI subsystem IDs, which is too simplistic. In theory (and often in practice) each PCI device has (or can have) its own subsystem ID. We should fix this, at least in v3, possibly also in v2.

#152: v3 Geode cs5536 UART2 wrongly configured

#152: v3 Geode cs5536 UART2 wrongly configured -------------------------------------------+-------------------------------- Reporter: edwin_beasant@… | Owner: somebody Type: defect | Status: new Priority: major | Milestone: Going mainstream Component: coreboot | Version: v3 Keywords: serial com2 geode cs5536 | Dependencies: Patchstatus: patch needs review | -------------------------------------------+-------------------------------- The UART2 on the AMD cs5536 is incorrectly configured in two places in v3 code and also in v2. GPIO lines 4 and 3 are swapped and also incorrectly put in IR mode receive (compound fault). This patch corrects the v3 late configuration and the v3 and v2 early (stage1/cache as ram) mis-configuration of UART2 to addres 0x3f8 not the standard 0x2f8 for COM2. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/152> coreboot <http://www.coreboot.org/>

#164: Building Coreboot v4 r5555/5554 fails mysteriously on Debian lenny and etch (x86) ----------------------------+----------------------------------------------- Reporter: juhe@… | Owner: stepan@… Type: defect | Status: new Priority: major | Milestone: Component: coreboot | Keywords: makefile, debian Dependencies: | Patchstatus: there is no patch ----------------------------+----------------------------------------------- I am trying to build Coreboot v4 from SVN with default settings, but I get build failures. The build environment is Debian Linux on x86. Process goes as follows: {{{ - check out coreboot trunk from SVN as per wiki instructions - run "make menuconfig", select QEMU hardware (default), ROM size either 256K or 1M - run "make": }}} {{{ coreboot.r5554$ make HOSTCC util/romcc/romcc (this may take a while) ROMCC mainboard/emulation/qemu-x86/bootblock.inc GEN bootblock/bootblock.c CC mainboard/emulation/qemu-x86/bootblock.s CC mainboard/emulation/qemu-x86/bootblock.o GEN bootblock/ldscript.ld LINK bootblock.elf OBJCOPY coreboot.bootblock HOSTCC cbfstool/common.o [..cut..] HOSTCC util/options/build_opt_tbl OPTION option_table.h GEN build.h ROMCC romstage.inc GEN romstage/crt0.S CC mainboard/emulation/qemu-x86/crt0.s CC mainboard/emulation/qemu-x86/crt0.initobj.o make: *** No rule to make target `/optbuild/lib/uart8250.initobj.o', needed by `build/coreboot.romstage'.

What is this directory /optbuild and why coreboot build is trying to create/access it? I tried to grep "optbuild" from the sources, but it does not seem to exist there. Trying the same on Debian/etch (older release): {{{ % make mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied mkdir: cannot create directory `/optbuild': Permission denied ROMCC mainboard/emulation/qemu-x86/bootblock.inc GEN bootblock/bootblock.c CC mainboard/emulation/qemu-x86/bootblock.s CC mainboard/emulation/qemu-x86/bootblock.o GEN bootblock/ldscript.ld LINK bootblock.elf collect2: ld terminated with signal 11 [Segmentation fault] make: *** [build/bootblock.elf] Error 1 }}} This looks like broken ld in Debian, or something going wrong in the build process. -- Ticket URL: <https://tracker.coreboot.org/trac/coreboot/ticket/164> coreboot <http://www.coreboot.org/>

flashrom patch: add support for Abit AB-BM6 board
by Tim ter Laak 14 Sep '10

14 Sep '10

Hello all, This patch adds support for the Abit AB-BM6 mainboard to flashrom. The biggest part is a generic function to lower a GPIO line on the PIIX4E southbridge, copied and adapted from its ich_gpio_raise() counterpart (mostly lower instead of raise, followed names from the PIIX4E datasheet). The board specific function then uses this to lower GPO 26. Signed-off-by: Tim ter Laak <timl(a)scintilla.utwente.nl> --- The patch was made from the flashrom subdir, because svn diff from the top-level coreboot dir (as per the directions in the Development Guidelines on the wiki) didn't seem to work for me. Probably because flashrom is fetched externally when checking out coreboot? Anyway, I hope this is okay. If you really prefer a diff from the top-level dir just let me know, and I'll regenerate it with gnu diff. Kind regards, Tim.

[PATCH] Istanbul support

Hi, The following patch implements Opteron Fam 10 rev D (aka Istanbul) support for coreboot. I have not updated MAX_CPUS for all fam10 mainboards, but it might make sense to multiply those by 1.5. Signed-off-by: Arne Georg Gleditsch <arne.gleditsch(a)numascale.com> -- Arne.
