[PATCH] new board: LiPPERT Cool SpaceRunner-LX

by Jens Rottmann

Add support for the LiPPERT Cool SpaceRunner-LX embedded PC board: - PC/104+ form factor - AMD Geode-LX CPU/northbridge - AMD CS5536 southbridge - ITE IT8712F superio Signed-off-by: Jens Rottmann <JRottmann(a)LiPPERTEmbedded.de> --- My previous mail still awaits list moderator approval, but I'm sending this anyway. :) Maybe you'll have to apply the patches from my previous mail first for this to compile. There are still large parts of coreboot's design that I don't fully understand yet, but I hope I did all right. All mainboard files are based on the AMD DB800. By the way, cmos.layout doesn't seem to be used (HAVE_OPTION_TABLE=0), still coreboot doesn't compile without it. Is there a designated way to use a global, generic file instead?

[PATCH] v2: ICH7: Drop/fix some ICH7 register #defines

by Uwe Hermann

This patch will fail to compile without my other patch to drop/disable the non-working enable_hpet() function in ICH7. Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

[PATCH] v2: ICH7: Drop non-working enable_hpet() for now

by Uwe Hermann

Please correct me if I'm wrong (I don't have NDA'd Intel datasheets, I can only check the public ones), but I think the enable_hpet() in the ICH7 code will not work for ICH7. It should work for ICH4/ICH5 or so, but ICH7 requires a completely different init involving RCBA, offset 0x3404, it seems. Thus, drop the non-working code, add a TODO until somebody writes the proper code for ICH7. Maybe I'll do that if nobody beats me to it, but it may take a while. Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

flashrom on EP80759 + Spansion S25FL016A

by Stephan GUILLOUX

Hello Carldani, You were right about the flash : this board is equipped with a ST flash and not with a Spansion... Now, I check the modifications we made yesterday night in flashrom. With them, flashrom is now working fine : I can read, I can write the flash content. Erase not tested. flashrom indicates that the ST M25P16 has a status 'untested' for operations PROBE READ ERASE WRITE. Tests and relevant traces are attached. If you need anything else, please, let me know. Best regards, and thx for help. Stéphan. PROBE works better with the 2nd fix (ich7 instead of ich_dc) READ/WRITE looks to work fine ERASE not tested Some modifications I added in flashrom code to have this work : 1) ST M25P16 works better with ich7 on EP80579 2) Initialize tmp to avoid garbage in the variable. ---------------------------------------------------------------------------------- diff -c flashrom-V2-3695/chipset_enable.c flashrom/chipset_enable.c *** flashrom-V2-3695/chipset_enable.c Sun Oct 26 19:40:42 2008 --- flashrom/chipset_enable.c Tue Oct 28 14:47:28 2008 *************** *** 765,771 **** {0x8086, 0x25a1, "Intel 6300ESB", enable_flash_ich_4e}, {0x8086, 0x2640, "Intel ICH6/ICH6R", enable_flash_ich_dc}, {0x8086, 0x2641, "Intel ICH6-M", enable_flash_ich_dc}, ! {0x8086, 0x5031, "Intel EP80579", enable_flash_ich_dc}, {0x8086, 0x27b0, "Intel ICH7DH", enable_flash_ich7}, {0x8086, 0x27b8, "Intel ICH7/ICH7R", enable_flash_ich7}, {0x8086, 0x27b9, "Intel ICH7M", enable_flash_ich7}, --- 765,771 ---- {0x8086, 0x25a1, "Intel 6300ESB", enable_flash_ich_4e}, {0x8086, 0x2640, "Intel ICH6/ICH6R", enable_flash_ich_dc}, {0x8086, 0x2641, "Intel ICH6-M", enable_flash_ich_dc}, ! {0x8086, 0x5031, "Intel EP80579", enable_flash_ich7}, {0x8086, 0x27b0, "Intel ICH7DH", enable_flash_ich7}, {0x8086, 0x27b8, "Intel ICH7/ICH7R", enable_flash_ich7}, {0x8086, 0x27b9, "Intel ICH7M", enable_flash_ich7}, ---------------------------------------------------------------------------------- diff -c flashrom-V2-3695/board_enable.c flashrom/board_enable.c *** flashrom-V2-3695/board_enable.c Sat Oct 18 23:14:13 2008 --- flashrom/board_enable.c Mon Oct 27 19:02:12 2008 *************** *** 250,256 **** */ static int board_asus_p5a(const char *name) { ! uint8_t tmp; int i; #define ASUSP5A_LOOP 5000 --- 250,256 ---- */ static int board_asus_p5a(const char *name) { ! uint8_t tmp = 0; int i; #define ASUSP5A_LOOP 5000 ---------------------------------------------------------------------------------- [root@lion04 root]# flashrom --read flash_content.rom Calibrating delay loop...

filo circular console list

by Arne Georg Gleditsch

Hi, The latest svn revisions of filo and libpayload (r83 and r3708) conspire to add the video console driver twice to the console_out list. This causes the list to become circular, with the effect that device_putchar spins in a loop printing the first character it is given. ("F".) Trivial patch and .config appended. (One might perhaps also consider making device_putchar or console_add_* more robust in the face of this kind of error, but I settled for this.) -- Arne. # # Automatically generated make config: don't edit # FILO version: 0.6.0rc1 # Thu Oct 30 12:01:16 2008 # CONFIG_TARGET_I386=y # CONFIG_REVIEW is not set # # Interface Options # CONFIG_USE_GRUB=y CONFIG_PROMPT="filo" CONFIG_MENULST_FILE="hde1:/grub/menu.lst" CONFIG_MENULST_TIMEOUT=3 CONFIG_USE_MD5_PASSWORDS=y # # Drivers # CONFIG_IDE_DISK=y CONFIG_IDE_DISK_POLL_DELAY=0 # CONFIG_SLOW_SATA is not set # CONFIG_PCMCIA_CF is not set CONFIG_USB_NEW_DISK=y # CONFIG_USB_DISK is not set # CONFIG_FLASH_DISK is not set CONFIG_SUPPORT_PCI=y # CONFIG_PCI_BRUTE_SCAN is not set # CONFIG_SUPPORT_SOUND is not set # # Filesystems # CONFIG_FSYS_EXT2FS=y CONFIG_FSYS_FAT=y # CONFIG_FSYS_JFS is not set # CONFIG_FSYS_MINIX is not set # CONFIG_FSYS_REISERFS is not set # CONFIG_FSYS_XFS is not set CONFIG_FSYS_ISO9660=y CONFIG_ELTORITO=y # CONFIG_FSYS_CRAMFS is not set # CONFIG_FSYS_SQUASHFS is not set # # Loaders # CONFIG_LINUX_LOADER=y # CONFIG_WINCE_LOADER is not set # CONFIG_ARTEC_BOOT is not set # # Debugging & Experimental # # CONFIG_EXPERIMENTAL is not set # CONFIG_DEBUG_ALL is not set # CONFIG_DEBUG_ELFBOOT is not set # CONFIG_DEBUG_ELFNOTE is not set # CONFIG_DEBUG_SEGMENT is not set # CONFIG_DEBUG_SYS_INFO is not set # CONFIG_DEBUG_BLOCKDEV is not set # CONFIG_DEBUG_VFS is not set # CONFIG_DEBUG_FSYS_EXT2FS is not set # CONFIG_DEBUG_PCI is not set # CONFIG_DEBUG_LINUXLOAD is not set # CONFIG_DEBUG_IDE is not set # CONFIG_DEBUG_ELTORITO is not set CONFIG_DEVELOPER_TOOLS=y

[PATCH] CN700/VT8237R stage2

by Corey Osgood

Attached patches for cn700, vt8237(r/s), and the mainboard, Jetway J7F2, along with a boot log. Currently, we're stuck in a reboot loop and I have no idea why, seems to be related to CAR disabling (this wasn't happening when disable_car was a noop). Carl-Daniel, any ideas? -Corey

what are ELF boot notes?

by Robert Millan

Hi, Does anyone know what "ELF boot notes" are? I've seen this reference in coreboot-v2/src/arch/i386/boot/boot.c. There's a struct named elf_boot_notes whose pointer is passed to the payload via %ebx, and a magic signature in %eax as well. Which is very similar to Multiboot (possibly inspired by it?), as it uses the same registers and is therefore impossible to support both things at the same time. This interface is not in v3. Does this mean it's no longer being used? If it's still in use with v2, I could add a build option that selects between them. -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and how) you may access your data; but nobody's threatening your freedom: we still allow you to remove your data and not access it at all."

Every revision from 1.03 and beyond seems to be publically available. Now the big question is: Can we decode HT 1.02 like HT 1.03 or have there been fundamental changes in between? I'd like to create a patch for PCIutils (lspci) so we can have full info without a warning message. Regards, Carl-Daniel -- http://www.hailfinger.org/
