HEAD isn't compiling with CONFIG_ANY_TOOLCHAIN
by Sean McNeil 10 May '14

10 May '14

Up until recently, compiling coreboot with the options CONFIG_COMPILER_GCC=y CONFIG_ANY_TOOLCHAIN=y on a 64-bit linux system worked just fine. Over the last few days I now get the errors: make Warning: no suitable GCC for armv7. Warning: no suitable GCC for aarch64. /bin/sh: -print-libgcc-file-name: command not found /bin/sh: -print-libgcc-file-name: command not found /bin/sh: -print-libgcc-file-name: command not found /bin/sh: -print-libgcc-file-name: command not found /bin/sh: -print-libgcc-file-name: command not found /bin/sh: -print-libgcc-file-name: command not found # # configuration written to .config # make: *** No rule to make target `build/cbfs/fallback/bootblock.bin', needed by `build/coreboot.pre1'.

No CBMEM console available for QEMU
by Paul Menzel 10 May '14

10 May '14

Dear coreboot folks, building coreboot for the target QEMU x86 q35/ich9 (aka qemu -M q35, since v1.4) I am unable to enable CBMEM console in the Kconfig menu (`make menuconfig`). As coreboot messages should be uploaded to the board status repository and only CBMEM console is supported, I wonder how to accomplish that. Thanks, Paul

coreboot at the LinuxTag 2014 in Berlin: Visit our booth at the community day this Saturday!
by Paul Menzel 10 May '14

10 May '14

Dear coreboot folks, just a heads-up, that coreboot is at the LinuxTag 2014in hall 5, booth H02 [1], which is on the first floor. The LinuxTag this year hugely changed compared to the last years. It changed location, only lasts three days and the Droidcon also there. On Saturday is the last day and they call it community day, where a ticket costs 10 €. The demo running coreboot/SeaBIOS and KolibriOS [2] from the flash ROM on the ASRock E350M1 is quite good and visitors like it. It boots in three to four seconds, where you have to press enter twice. Big thanks to Scott to making that possible this week by sending patches to the list! Besides that it is as every year, where interested people stop by and mostly ask, if coreboot is going to run on their hardware. Big thanks to Peter for being there all three days and organizing a booth. Unfortunately I won’t be able to be there tomorrow. So enjoy and see you at next year’s LinuxTag in Berlin! Thanks, Paul [1] http://www.linuxtag.org/2014/de/ausstellung/aussteller/

CBMEM console and time stamps not working with 99ac98f7
by Paul Menzel 10 May '14

10 May '14

Dear coreboot folks, building commit 99ac98f7 [1] Introduce stage-specific architecture for coreboot for the ASRock E350M1, I noticed that neither CBMEM console nor CBMEM time stamps are saved. Could somebody please try it on another board? Thanks, Paul [1] http://review.coreboot.org/5577

As I noted, this is third hand knowledge, but: the allwinner CPUs have a boot ROM somewhere in the chip. The code is immutable (hence ROM) and rather tiny. My mistake is two-fold: one, it's not about signed code, but about immutable one - but since it can be read, it can be analyzed, and so besides the "it's immutable so it's not software" defense, its impact is well-known. Second, after re-reading my notes I'm not quite clear if that analysis was actually conducted by "our" dev or someone else. Whatever the case, Alex certainly knows a lot of things about the Allwinner now and considers it good from a blob perspective, and I happily rely on the expert. If in doubt he knows more about that chip than I do (but he's offline for the next 10 weeks or so).

Ron, The current coreboot already supported Sandy Bridge FSP, downloading a Sandy Bridge FSP form Intel website and placing it to current coreboot, it might work immediately. -Fei On Fri, May 9, 2014 at 9:21 PM, ron minnich <rminnich(a)gmail.com> wrote: > Oh no, I don't want to try FSP, I just want to do the thing that's the > least work for me, and it sounds like Google mrc.bin is what I want, > since I know where to find it :-) > > Thanks > > ron > > -- > coreboot mailing list: coreboot(a)coreboot.org > http://www.coreboot.org/mailman/listinfo/coreboot >

It matters in that it can be checked. It also matters that fixes are possible: I had to binary patch an Intel bug in Google's MRC binary, it would have been easier to find in source code (in particular because I've been told that the comment above the point I fixed actually said the right thing. I had no comments in the binary to work with). In an open source process (with feedback loop) I could even have pushed that fix your way. As-is I have no idea who's still affected by that bug. Also, this argument only works because the data sheets are locked down. I still have some vain hope that this will change at some point, too. :-) The PC space thrived because/despite (pick your favorite) open data sheets, and the embedded space still does (see also: Quark). One more advantage open source brings is that it provides standardized licensing (and this issue is more important to commercial integrators that want to sell their work than to private developers): Mainstream open source licenses are well-known, battle-tested in courts around the world, and companies tend to have (simple) policies on using code under open source terms in products. I was recently told that the FSP license is different from the click-through license on www.intel.com/fsp (the one shown when trying to download the files). So here's how I understand the FSP license situation: There's the click-through license on the web site, the FSP license (shown by the self-extracting archive), the intersection of both that actually applies to me when using FSP, and the application of these resulting terms in jurisdictions world-wide. And every single-letter change to the license in future releases restarts the license evaluation process from scratch. This may not be a problem for Intel - it's huge so these things don't matter much, but please keep in mind that Intel's legal department alone is probably larger than many of the companies that integrate Intel's chips. So custom licensing is certainly a great scheme to keep lots of lawyers employed. But it's not so great if you're just trying to get chipset initialization code (and by extension: chipsets) into the hands of integrators. > ARM has a Boot ROM inside their SOC, should the code inside the Boot > ROM be open? or does it matter? Those tend to be small, in the 4-8kb range, and focused on a single purpose: getting the next stage into iRAM. For the Allwinner CPU we support, one developer in our community checked that the signed binary-only part (that we can't replace) is harmless. This isn't so easy with a multi-100kb binary affecting pretty much everything across multiple chips. > I know this view point is not going to be popular, but Intel is trying > hard to open as much code as possible (tianocore.org [1], Linux > drivers, and Quark firmware are a few examples; I am sure more will > come in the future).

The data points collected on #coreboot indicate that you're better off with the Google mrc.bin. The data is so strong that I think there's a need to wrap FSP in an mrc.bin-style interface to localize the damage inflicted by future platforms to the poor soul that gets to work on the wrapper. But if you're truly interested in trying FSP, rest assured that I'm in no way trying to discourage you.

FSP, SNB, and a new board

How good is the FSP code with a new board? I have an SNB board and I'm curious as to how much blood will be on the walls if I try to use an FSB-based coreboot image with it. SNB = my weird way of saying sandybridge ron
