[PATCH] Fix VIA VX*** support.
by Stefan Tauner 31 Jul '12

31 Jul '12

Helge Wagner's patch that added VIA VX900 chipset support made me look closer at the datasheets which led to some concise documentation about newer VIA chipsets: http://flashrom.org/VIA Based on that this patch adds full support for VX800/VX820, VX855/VX875 and VX900, including SPI and LPC. VT8237S was not changed (SPI support only) because there is no public datasheet and it is not clear how to distinguish between LPC and SPI strapping and investigations in (NDAed) documents have not brought up anything conclusively. enable_flash_vt823x could probably be enhanced too due to various yet ignored LPC options of the chipset.

I plan to tag and release flashrom 0.9.6 Real Soon Now (tm). If you need anything merged, tell me NOW. flashrom svn HEAD doesn't have any known regressions compared to 0.9.5, so it seems stable enough to ship. Regards, Carl-Daniel -- http://www.hailfinger.org/
