If no one have yet taken it up, i am interested in doing the work, i will sponsor myself :). i will proceed at a slow pace without derailing my other things normal. To keep expectations realistic: i have not yet taken task of this complexity, it is more of a learning for me. My familiarity with Linux at the ARM architecture level is mostly on no-MMU (Cortex-M), have not worked so far seriously on MMU Linux at the ARM architectural level, though used to go through ARM ARM v7-AR at times. i have a few 32-bit ARM Cortex-A (A5, A8 & A9) boards, maximum RAM 1G, none have LPAE, seems i have to buy one for this purpose. And if someone else wants to do it, i will not take it up. Regards afzal
