[U-Boot] [PATCH] mxsboot : Support of 224-bytes OOB area length

[U-Boot] [PATCH] mxsboot : Support of 224-bytes OOB area length

[Alexandre Coffignal]

Add support for the NAND Flash chip with page size of 4096+224-bytes OOB area length 

For example Micron MT29F4G08 NAND flash device defines a OOB area which is
224 bytes long (oobsize).
