2011-10-28Fix checksum calculation both in romstage and ramstage.Stefan Reinauer
The earlier fix for CMOS checksums only fixed the function rtc_set_checksum, which would fix the checksum, but then coreboot would no longer honor the settings because it assumed the checksum is wrong after this. This change fixes the remaining functions.

2011-10-17Fix our CMOS checksum algorithm so it matches what /dev/nvram expectsStefan Reinauer
Our cmos checksum is inverted to what the Linux /dev/nvram device expects (and BIOSes use). This makes it impossible to use /dev/nvram with coreboot. Fix it!

This reverts commit eb7bb49eb5b48c39baf7a256b7c74e23e3da5660. Stepan pointed out that "s" means string, which makes the following statement in this commit message invalid: "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."

2009-06-03CMOS: Add set_option and rework get_option.Luc Verhaegen
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.
