Ok. communication error here. You will only have the coreboot tables when coreboot has succesfully booted and your config has USE_OPTION_TABLE. But... like with many of the other epia boards, you will never disable rom access from coreboot and therefor flashrom does not need to enable specifically for this board. So: * original bios has an extra write disable, but also has subsystem ids. here flashrom should use the subsystem ids to autodetect this board. * coreboot, from reset, should not touch set the board specific disable. So flashrom doesn't need to know or touch this. * when coreboot is ran after the normal bios, the subsystem ids usually still are there, and so is the write protection (if you're plugging chips). Flashrom then should still autodetect through subsystem ids still. So, do you really need flashrom to run the board specific enable when you've booted coreboot? If not, remove the coreboot ids, and also make it impossible for people to randomly try board enables (through the command line) and accidentally hit this code. I am quite happy with the rest of the code though. Luc Verhaegen.

[PATCH] flashrom: Add -z for wiki syntax output (try 3)
by Uwe Hermann 19 Jun '09

19 Jun '09

See patch. This is the third iteration, now all code is in print.c together with the other printing code. The output now also contains chip size (in KB) and type (parallel, LPC, FWH, SPI). The page at http://www.coreboot.org/Flashrom already contains the current -z output (as of yesterday) including new fields for chip size and type.

[flashrom] r607 - trunk

Author: uwe Date: 2009-06-19 12:42:43 +0200 (Fri, 19 Jun 2009) New Revision: 607 Modified: trunk/flash.h trunk/flashrom.8 trunk/flashrom.c trunk/print.c Log: Add a --list-supported-wiki / -z option which outputs the currently supported flash chips (and their status, size, and type), chipsets (plus status), mainboards (plus status), and external PCI devices usable as programmer to stdout. This allows for very easy pasting into the http://coreboot.org/Flashrom page, so we can keep that page up-to-date without much hassle. The list of boards is mostly new (known good ones which don't need write-enable code, and known-bad ones) and also lists URLs to the vendor's mainboard pages.

Adding CAR support to v2
by ron minnich 18 Jun '09

18 Jun '09

This is the beginning of CAR support for v2 for qemu. It is done in such a way that few changes are required and, more the the point, romcc-based qemu targets keep working and remain the default for now. It builds on but substantially improves the v3 model, a most important point being that there are *no* included code files in .c or .S. The .S code is from v3, however. This is working and boots to linux in both car and non-car versions. Note that I use the name 'rom.c' instead of the awkward 'cache_as_ram_auto.c'. Some work remains. We need to have a standard rom main as we do in v3 (we call it stage0/1 in v3). But this is a good start IMHO. comments from the patch: Note that the current non-CAR implementation is the default and continues to work (tested FILO boot to Linux on both CAR and non-CAR). Index: src/mainboard/emulation/qemu-x86/Config.lb Change this to be sensitive to USE_DCACHE_RAM. All settings etc. that depend on this variable are grouped in one if, and the other parts (romcc etc.) are in the else. This change is a model of how we should be able to do other motherboards. Index: src/mainboard/emulation/qemu-x86/Options.lb add needed options. Index: src/mainboard/emulation/qemu-x86/failover.c remove code inclusion from this not-yet-used file. Index: src/mainboard/emulation/qemu-x86/rom.c This is the entry point for the rom-based code. Called stage1.c in v3. Index: src/lib/Config.lb change initobject to a .o from a .c; this fixed a build problem. Index: src/pc80/serial.c make uart_init non-static. Index: src/pc80/Config.lb add initobject Index: src/arch/i386/init/entry.S Entry point. Unify a bunch of files that were fiddly lttle includes. From v3. Index: src/arch/i386/init/ldscript.ld new file. The goal is to hang all init changes for CAR here, to minimize other changes to any other ldscript. Besides, putting this in init makes sense; entry and car are manage init. Index: src/arch/i386/init/car.S generic i386 car code from v3. Index: src/arch/i386/init/ldscript_fallback_cbfs.lb Fix what looks like a bug: this was not including the init.text section. Index: targets/emulation/qemu-x86/Config.lb push up the console loglevel. qemu is for debugging so we might as well get all the debugging we can. Index: targets/emulation/qemu-x86/Config-car.lb For CAR bullds. Signed-off-by: Ronald G. minnich <rminnich(a)gmail.com> ron
