* MRC cache: determine flash size on runtimeVladimir Serbinenko2014-01-061-4/+4
| | | | | | | | | | | | | | | It should be possible to put coreboot compiled for smaller chip by putting it at the end of bigger chip. We already have chip size in flash->size. Use it. Tested on Lenovo X230.

| | | | | | | | | | | | | Location is hard-coded right now, which isn't optimal. It must be chip erase block aligned, which might fail on some flash chips (it's 64k aligned which should work for most cases).

* Avoid using hardcoded values in MRC cache codeVadim Bendebury2012-11-121-77/+103
| | | | | | | | | | | | | | | | The MRC cache code, as implemented, in some cases uses configuration settings for MRC cache region, and in some cases - the values read from FMAP. These do not necessarily match, the code should use FMAP across the board. This change also refactors mrccache.c to limit number of iterations through the cache area and number of fmap area searches.

* SandyBridge/IvyBridge: Use flash map to find MRC cacheStefan Reinauer2012-11-071-6/+12
| | | | | | | | | | | | | | | | | | | | | | Until now, the MRC cache position and size was hard coded in Kconfig. However, on ChromeOS devices, it should be determined by reading the FMAP. This patch provides a minimalistic FMAP parser (libflashmap was too complex and OS centered) to allow reading the in-ROM flash map and look for sections. This will also be needed on some partner devices where coreboot will have to find the VPD in order to set up the device's mac address correctly. The MRC cache implementation demonstrates how to use the FMAP parser.

* Fix MRC cache update delaysStefan Reinauer2012-07-241-14/+22
| | | | | | | | | | | | | When no valid MRC cache area is found, the mrc_cache data structure was used without prior initialization. This sometimes caused a long delay when booting because compute_ip_checksum would checksum up to 4GB of memory.

* Sandybridge: Remove remnants of FDT support from MRC cache codeStefan Reinauer2012-05-291-69/+11
| | | | | | | | | | | | | | Originally, ChromeBooks would get the offset of the MRC cache from an entry in the u-boot device tree. Not everyone wants to use u-boot on Sandybridge systems, however. Since the new code (based on Kconfig) is now fully working, we can drop the u-boot device tree remnants.

* Rework Sandybridge MRC cache handlingStefan Reinauer2012-05-111-0/+265
- Separate Sandybridge from ChromeOS a bit The Sandybridge code depends on chromeos features a whole lot. As a first step, provide a code path to look up the MRC cache without depending on u-boot. - Move mrc cache handling to separate file This enables us to handle the MRC cache from ramstage, where we can write the flash safely (eg. to update the cache). Also teach it to lookup the current MRC cache from CBMEM, as the original data block isn't available anymore. After all the preparations, finally write to the SPI as necessary. It's a simple round robin wear levelling that erases the entire MRC cache region when it's full and starts from the beginning.
