The following series adds support for the Freescale mpc8272ads board under arch/powerpc. Assuming 8560 series applied. Relevant patches are also available in git:/git.kernel.org/pub/scm/linux/kernel/git/vitb/linux-2.6-PQ.git in testing branch. -- Sincerely, Vitaly

This has modules of common directories related to the mpc8272ADS board, mainly common cpm2 changes and fsl_soc.c portions related to the bitbang MDIO and other mechanisms specific for this family.

This intruduces 82xx family in arch/powerpc/platforms, and has all the board-specific code to represent regression-less transaction from ppc. The functionality is apparently the same, including PCI controller.

Paul, Sorry, this patch is broken - something screwed up git commit it seems... I'll resend ASAP. -Vitaly On Fri, 22 Sep 2006 06:48:44 +0400 Vitaly Bordug [off-list ref] wrote:
