Do you know the revisions used on imx31 and imx35? Or do you see that enabling the workaround help fix some real issues?

The reason I selected these two errata was due to comparison with the FSL BSP defconfig for mx31: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/configs/imx31_3stack_defconfig?h=imx_2.6.31
