[PATCH] v3: Explain the ld options for initram
by Carl-Daniel Hailfinger 08 Nov '08

08 Nov '08

initram is linked with very special options to ld. It is not immediately obvious that they are needed, so a comment to that effect will hopefully prevent accidental "cleanups" in the future when nobody remembers the history of that makefile rule anymore.

Source code download difficulties
by Ken.Fuchs＠bench.com 08 Nov '08

08 Nov '08

I'm able to easily download the coreboot kernel from qa.coreboot.org, but all ancillary source code like FILO and libpayload are not easy to download. I'm behind firewall/proxy that allows only http and maybe https (with _valid_ certificates). In addition, the coreboot.org SSL certificate doesn't seem to be validated by a recognized certificate authority. $ svn co https://coreboot.org/svn/trunk/coreboot-v2 svn: PROPFIND request failed on '/svn/trunk/filo' svn: PROPFIND of '/svn/trunk/filo': 405 Method Not Allowed (https://coreboot.org) There seems to be a way to use tracker to get zip files of source code, but it doesn't seem to be available for all coreboot projects. What is the recommended way to get coreboot ancillary project source code like FILO and libpayload when svn and https/WebDAV protocols are not available or don't work? All coreboot source code should be available via one or more tarballs (like the coreboot kernel itself). Sincerely, Ken Fuchs

Re: [coreboot] alix2c3 LEDs and mode switch

There is fully functional linux kernel driver (see attachment) which works flawlessly with tinybios (alix factory bios). I want to indicate software status events (for example network is up or down) using custom scripts and driver I've mentioned. Roman

and/or busybox issue with alix2c3 serial console
by Roman Yeryomin 08 Nov '08

08 Nov '08

I'm experimenting with coreboot (v3) on alix2c3 and still can't get serial console working. :( It stops right after kernel is done booting (I can see coreboot, filo and kernel messages just fine). I use openWRT but tried also another busybox based distribution (imedialinux) -- same problem. With original tinybios no problem. At the same time I tried voyage linux (without busybox) with corebooted alix and it has no such problem. It's obvious that this problem cannot be identified as 100% busybox's (why then it works on tinybios?). While digging coreboot sources I've noticed that uart initialization is done twice for this board -- once in /southbridge/amd/cs5536/cs5536.c (based on dts config) and second time in /mainboard/pcengines/alix2c3/stage1.c. I tried playing with these (and /southbridge/amd/cs5536/stage1.c), disabling one code or another, but no luck. Tried to set MOD bits: msr.lo = (1 << 4) | (1 << 5) | (1 << 6); msr.hi = 0; wrmsr(MDD_UART1_MOD, msr); Also no luck. Not enabling upper banks, however, makes uart appear in kernel as regular 16550A (and not as NS16550): /* Bit 1 = DEVEN (device enable) * Bit 4 = EN_BANKS (allow access to the upper banks) */ //msr.lo = (1 << 4) | (1 << 1); msr.lo = 1 << 1; msr.hi = 0; So... where should I go now? I'm really stuck. Begging for help... Regards, Roman
