Open Firmware

  • 3505 OLPC XO-4 - EC Code 0.3.07,
  • 3504 OLPC XO-4 - touchscreen, change to version, which caused a few more timing changes, requiring some fixes to the driver.
  • 3503 .caller - minor stack comment fix, no execution effect,
  • 3502 OLPC XO-4 - fix support for non-touchscreen SKUs, compatible with touchscreen SKUs, treats TOUCH_HD# signal as active high, since the touchscreen controller is pulling the signal low in normal operation, momentarily enables a pull-down in conflict against the permanent pull-up, in order to sample the signal properly. Requires a BOM change for C2. Harmless on C1. ticket #12391
  • 3501 OLPC XO-4 - EC Code 0.3.06 (redundant),
  • 3500 OLPC - allow a touchscreen, if present, to prevent automatic test execution after left rocker key, ticket #11817.
