[flashrom] Asus A7N8X-E Support.
by Luc Verhaegen 22 May '09

22 May '09

With the discussion of the board_enables table, i ended up looking at the flashrom page on coreboot.org and spotted a bunch of boards that are known to not work. The first one i looked at was the aforementioned and this here is what is needed for the flash enable of that board. { uint8_t tmp; pci_write_byte(dev, 0x92, 0); tmp = pci_read_byte(dev, 0x6D); tmp |= 0x01; pci_write_byte(dev, 0x6D, tmp); } While it seems that the second operation seems to match both ck804 and mcp55 chip enables, this is not true. The device used is 0:01.0 (ISA bridge) and not 0:01.1 (SMB controller). I googled, but could not find a report to the coreboot (or linuxbios) list of this board being tested. Does anyone remember who reported this as broken? Luc Verhaegen.

[patch] flashrom: resending my patch about SPI/LPC conflicts
by Bao, Zheng 18 May '09

18 May '09

Signed-off-by: Zheng Bao <zheng.bao(a)amd.com> This patch is about flashrom running on dbm690t. It was sent several months ago and hasn't got any response yet. Now it deals with 3 problems. 1. Fix the bug that the flashrom would hang if there is not SPI chip. A timeout detection was added. 2. We only access LPC ROM if we boot via LPC ROM. And only SPI ROM if we boot via SPI ROM. Doing crossly is not allowed. Anybody has better idea? 3. When we read/write SPI, we use memory read/write instead of sending SPI command. Joe

Our plans are to go through our current product listings and see if we can get FlashROM to work on them. We want to be able to add something other than AMI, Award or Phoenix as a flash utility for our customers. We have been pleased with what the FlashROM utility does and we are working on further validation with this particular utility. Thanks again for your reply and we will continue to stay in touch as new updates are made available.

If a specific mainboard was tested and is working, please send a mail containing the mainboard and the flash chip you used, and what you tested on that mainboard+flash combination (verify, read, erase, write) to either coreboot(a)coreboot.rom or flashrom(a)coreboot.rom. Then we can update the web pages accordingly. In case you wish to have new, currently unsupported mainboards supported by flashrom, let us know here, too. I think we can help.

[PATCH] v1: Add license headers to AMD AMD-768 code
by Uwe Hermann 15 Apr '09

15 Apr '09

Yay, my first v1 patch :) Eric, any other code chunks which were mostly/entirely written by you where we can slap a GPLv2 header on? AMD-766, others? Btw, was this code from 2003 (C) Eric W. Biederman or rather (C) LNXI? Thanks, Uwe. -- http://www.hermann-uwe.de | http://www.holsham-traders.de http://www.crazy-hacks.org | http://www.unmaintained-free-software.org

Paraflasher Update
by Joseph Smith 29 Mar '09

29 Mar '09

Hello, Just wanted to let everyone know I finally had time to finish the Paraflasher board with the SOIC FET Bus Switch With Level Shifting. I uploaded new images. I just have to get a daughter board togethor with a PLCC32 socket on it and I will be ready to get going on a flashrom add-on. Check out the new images: http://www.coreboot.org/Paraflasher -- Thanks, Joseph Smith Set-Top-Linux www.settoplinux.org

[PATCH]es 7 assorted fixes
by Jens Rottmann 19 Mar '09

19 Mar '09

route_irq15.diff (changes pirq_routing.c): Fixes a off-by-one error when routing the IRQs. This led to IRQ15 not getting assigned. autoboot_delay.diff (changes filo.c): Fixes compile error when AUTOBOOT_DELAY=0. dword_copy.diff (changes crt0.S.lb, cache_as_ram.inc (Geode LX)): Speed up copying coreboot to ram by using "movsl" instead of "movsb". Also use different console messages for copying and uncompressing, like it's already done in similar code in other places. speed_calc.diff (changes raminit.c (Geode LX)): Changed RAM speed calculation to fix RAM modules getting rejected only due to integer rounding errors. Previously, the formula was: speed = 2 * (10000/spd_value) For spd_value=60 this means speed = 2 * 166 = 332, which is less than 333 and coreboot died saying RAM was incompatible. The new formula is: speed = 20000 / spd_value For spd_value=60, speed=333, which is fine. await_ide.diff (changes ide.c): Made await_ide(), which polls for an ide status change, check the status reg much more often. In my case this reduced the time spent in coreboot by 1.5 sec! The timeout values of course aren't changed, only the granularity. Also, I didn't see any udelay() implementation that looked like it couldn't cope with 10 us delays. (Most are written as for (...) inb(0x80) loops.) fs_arch.diff (changes ext2fs.c, fat.c): #if ARCH == 'i386' results in a compile error: character constant too long (or something alike). Changed it to #ifdef __i386 I'm unsure if this is correct, though! Why didn't anyone hit this problem before? Is this some ROMCC-special? it8712_gpio.diff (changes superio.c (IT8712F)): Added the missing I/O resources for IT8712F GPIOs. Our boards need these e.g. to switch the com ports between RS232 and RS485. Signed-off-by: Jens Rottmann <JRottmann(a)LiPPERTEmbedded.de> --- Above are fixes for some issues I tripped over while working on coreboot support for some of our boards. The patches can be applied in any order. (Should I have sent 7 seperate mails? I deemed it easier this way ...) I'll contribute the actual mainboard files as soon as I'm done.
