Author: quozl Date: Tue Oct 25 08:16:34 2011 New Revision: 2654 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/2654 Log: OLPC XO-1.75, XO-1.5, XO-1 - battery state of charge did not properly show 100%. The cause was that a previous definition of 2.d was being used, which used (.2), truncating any higher digits. This wasn't a problem until the XO-1.75 EC started using 100% instead of 97% in commit ea52c0c. Batteries moved from XO-1.75 to XO-1.5 and XO-1 may show 00% in watch-battery or .bat until this fix is released.
