[PATCH] use coreboot.rom for CBFS images, but default to smaller size
by Patrick Georgi 01 Jun '09

01 Jun '09

Hi, attached patch changes the bootblock generation for CBFS images. It uses coreboot.rom (padded and all), but defaults to smaller fallback/normal image sizes. It requires changes to each CBFS aware mainboard config (and requires adaption on conversion), but it fixes using normal image (as the offsets are calculated correctly). I tried to get rid of ROM_IMAGE_SIZE and friends, but that'll have to wait until non-CBFS images are gone - maintaining two separate build configurations in a single build system isn't fun. If this gets accepted, I'll propose a patch for the (few) CBFS boards, and commit them together. Signed-off-by: Patrick Georgi <patrick.georgi(a)coresystems.de> Patrick

Mptable fix for M57SLI
by Harald Gutmann 01 Jun '09

01 Jun '09

Hello, I've given it another try to fix the mptable of the M57SLI. The attached patch fixes for me the following things: * Nvidia graphic device works on PCIe-16x slot (black). * Both PCI cards in the two available slots work fine. * Also the PCIe 1x slots should work fine. (untested) It would be fine if someone of you could test and verify if that patch works on hardware revision v1 too. I hope that this fixes all the problems along with interrupts for this mainboard and I'm looking forward that someone can verify/test this. Kind regards, Harald PS: Is it necessary to add PCI_INT for 00:08/07.01-03?

MSI 7135 verbose lspci output
by David Hendricks 01 Jun '09

01 Jun '09

Attached is an lspci dump for the MSI 7135 (K8N Neo3) board. jakllsch did a v2 port for this board last year. Flashrom works, but only if you do -m msi:k8n-neo3 for erase and write operations. Uwe suggested posting the lspci contents in case someone has a few spare cycles to try and implement auto-detect for this board in flashrom.

[PATCH] flashrom: Only probe for chips with compatible bus protocols
by Carl-Daniel Hailfinger 01 Jun '09

01 Jun '09

Only probe for chips with compatible bus protocols. It doesn't make sense to probe for SPI chips on a LPC host, nor does it make sense to probe for LPC chips on a Parallel host. This change is backwards compatible, but adding host protocol info to chipset init functions will speed up probing. Once all chipset init functions are updated and the Winbond W29EE011 and AMIC A49LF040A chip definitions are updated, the W29EE011 workaround can be deleted as the W29/A49 conflict magically disappears.

[flashrom] nic3com: address lines
by Mats Erik Andersson 01 Jun '09

01 Jun '09

Hello all, using a signal probe I can verify two facts: 1) 3c905B has address lines A0 -- A16 routed, but not A17. Thus 128 kB is the maximal capacity achievable. 2) 3c905 only routes the adress lines A0 -- A15, and therefore limits itself to only 64 kB. On the other hand, I have not succeeded in getting even read capabilities going in my own code (not your "flashrom"). As a side note, rtl8138C and via-rhine VT6102 are already a priory bounded by 64 kB. Both are easily usable by straight forward coding. In contrast, eepro100 seems to be usable by ctflasher only due to their repeated probing. One time probing, as in my efforts, have yet to prove successful. Best regards Mats Erik Andersson

[PATCH] flashrom: Add bus type support to -p dummy
by Carl-Daniel Hailfinger 01 Jun '09

01 Jun '09

Add bus type support to the dummy external programmer. The syntax is explained in the man page. Example: flashrom -p dummy=lpc,fwh Tested, works perfectly. ;-) As a nice benefit, it allows easy testing of the "probe only compatible flashes" patch.
