ubi-utils: bin2nand, nand2bin add support of different ecc layouts
Both tools were lacking support of alternate ECC layouts. Only our intitial format was supported. With this change, it should be very easy to add more layouts in addtion to the already supported ones, which are: IBM (our format), and the MTD default layout. NAND OOB sizes of 512 and 2048 are currently supported. In contrast to the old version of bin2nand, the holes inbetween the ECC data is now not filled with 0x00 anymore but instead 0xff (like deleted flash) is used. This should not cause any difference. The testcase reflects the different layouts too. Signed-off-by: Frank Haverkamp <haver@vnet.ibm.com>
