Dear coreboot readers!
This is the automatic build system of coreboot.
The developer "libv" checked in revision 4332 to the coreboot repository. This caused the following changes:
Change Log: CMOS: Add set_option and rework get_option.
To ease some of my debugging pain on the unichrome, i decided i needed to move FB size selection into cmos, so i could test a size and then reset it to the default after loading this value so that the next reboot uses the (working) default again. This meant implementing set_option in parallel to get_option.
get_option was then found to have inversed argument ordering (like outb) and passing char * and then depending on the cmos layout length, which made me feel quite uncomfortable. Since we either have reserved space (which we shouldn't do anything with in these two functions), an enum or a hexadecimal value, unsigned int seemed like the way to go. So all users of get_option now have their arguments inversed and switched from using ints to unsigned ints now.
The way get_cmos_value was implemented forced us to not overlap byte and to have multibyte values be byte aligned. This logic is now adapted to do a full uint32_t read (when needed) at any offset and any length up to 32, and the shifting all happens inside an uint32_t as well. set_cmos_value was implemented similarly. Both routines have been extensively tested in a quick separate little program as it is not easy to get this stuff right.
build_opt_tbl.c was altered to function correctly within these new parameters. The enum value retrieval has been changed strol(..., NULL, 10) to stroul(..., NULL, 0), so that we not only are able to use unsigned ints now but so that we also interprete hex values correctly. The 32bit limit gets imposed on all entries not marked reserved, an unused "user_data" field that appeared in a lot of cmos.layouts has been changed to reserved as well.

Build Log: Compilation of kontron:986lcd-m has been broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4332&device=986lcd-m&am...
If something broke during this checkin please be a pain in libv's neck until the issue is fixed.
If this issue is not fixed within 24h the revision should be backed out.
Best regards, coreboot automatic build system
