Open Firmware

  • 3566 OLPC XO-4 - EC Code 0.3.13
  • 3565 ARM - increased max-image because some OFW dictionaries are now starting to exceed 1 MiB.
  • 3564 OLPC ARM - memtest, did not reset diag-switch? and led to net boot, ticket #12564.
  • 3563 inet - add remote diagnosis console feature, increase verbosity of telnet and telnetd, include telnetd in build rather than autoload from source, and allow other port numbers for outbound telnet.
  • 3562 core - mux, add console add and remove, for use by telnetd
  • 3561 inet, tcpapp, add support for applications that accept connections.
  • 3560 OLPC - libertas, fix failure during test /wlan on 8686, by returning separate scan response result and length.
  • 3559 OLPC XO-1.75 XO-4 - autorun tests, add redundant text and a stall point for overall pass or fail. ticket #12515.
  • 3558 OLPC XO-4 - sdhci, device tree, set a non-removable attribute for internal microSD slot, ticket #12561.
  • 3557 OLPC - libertas, add support for 802.11n 5 GHz networks on 8787. Due to a firmware limit of 14 channels in a scan request, the scan logic was heavily changed. During association a specific channel scan order is followed, and the first match stops further scanning. The LEDs test was also changed to reduce the time taken. ticket #12552.
  • 3556 OLPC XO-4 - touchscreen, restore missing test instructions during scribble and axes tests, fixes a regression introduced in r3535. ticket #12553.
  • 3555 OLPC - startup sound. Avoid searching jffs2 filesystem on XO-1 because mounting it takes a long time. Avoid checking for file existence; just try and if we fail, fallback to the built-in sound. Avoids one microSD or eMMC power cycle from boot on XO-1.5, XO-1.75, and XO-4 when the startup sound is present.


  • revert: set PJ_FORCE_PCLKON in PMUACC2PJ for static clock change
