Ivan,
In the commit 702b94bff3c50542a6e4ab9a4f4cef093262fe65 (2.6.34) the
functions
dmac_inv_range and dmac_clean_range were removed.
I'm wondering how to fix this in order to rebase to 2.6.34.
Thanks
2 options:
1. Replace dmac_inv_range and dmac_clean_range functions with the new dma

Fernando,
+ if (cpu_is_omap2420() || cpu_is_omap3430() ||
+ cpu_is_omap3630() || cpu_is_omap44xx())
looks like this check is applied to all OMAPS. Can we just remove this check ?
Thank you,
Best regards,
