Thus the +driver will erase the whole nand flash and create a new block table. + +TODO: + - Enable Command DMA feature support + - lower the memory footprint + - Remove most of the unnecessary global variables + - Change all the upcase variable / functions name to lowercase + - Some other misc bugs + +Please send patches to: + Greg Kroah-Hartman <gregkh@suse.de> + +And Cc to: Gao Yunpeng <yunpeng.gao@intel.com> + |
