== Summary ==

This specification tracks the status of support for the Freescale Babbage board for the Karmic 9.10 cycle.

== Release Note ==

Ubuntu 9.10 has extended support to the Freescale Babbage2 Board. Babbage1 support has been dropped.

== Rationale ==

The Babbage2 board is the next generation of the iMX51 platform, is the target hardware for FSL for this cycle.

== Requirements for Implementation ==

 * 2.6.31 series kernel for iMX51 Babbage2 lands in Ubuntu git tree
 * redboot (or uboot) sources for the Babbage2 materialize, and are merged into the redboot-imx package in the archive.
 * Additional hardware for testing and debugging becomes available

=== Code Changes ===

 * ubuntu-cdimage
   - Needs to be updated to use need redboot-tools -OR- if we move to u-boot this cycle, modified to create uboot images
   - Descriptions need to be updated for TO2 support
 * linux kernel
   - Current codedropped from FSL have support for 7 SoCs, we only support fo the iMX51
   - Latest kernel only 2.6.28, kernel team needs to fowardport to 2.6.31
 * debian-installer/base-installer
   - Subarchitecture detection will have to be updated to detect the Babbage2's /proc/cpuinfo string
 * flash-kernel
   - Subarchitecture detection will have to be updated to detect Babbage2 in addition to Babbage1
   - Will need update to new redboot-tools or uboot-tools depending on the state of bootloader support
 * iso.qa.ubuntu.com
   - Will need to be updated for imx51 for karmic (requires RT ticket filed, should be done after we have images building)

=== Migration ===

 * No migration will be supported from Babbage1 to Babbage2. Depending on kernel support, Babbage1 support may remain in 9.10 in an unsupported state

== Test/Demo Plan ==

Normal ARM/Desktop image test cases can be used to test image.

== Unresolved issues ==

 * Lack of development hardware for the team (total of four Babbage2's available)
