[U-Boot] [PATCH 5/6] cmd: mtdparts: support runtime generated mtdparts

2016-06-05 Thread Ladislav Michl
Some CPUs contains boot ROM code capable reading first few blocks (where SPL resides) of NAND flash and executing it. It is wise to create separate partition here for SPL. As block size depends on NAND chip used, we could either use worst case (biggest) partition size or base its size on actual
