mtd-utils: nandwrite: full 64-bit support w/ libmtd
Several ioctls are replaced with libmtd calls which should give us 64-bit
support for large devices. libmtd mostly provides drop-in replacements
for the functionality we need. However, when we require erasure of a
badly-written block, mtd_erase() only erases a single block, whereas
MEMERASE could erase a larger region. In nandwrite, we may have a "virtual
blocksize" of more than one (when blockalign > 1). Thus, I added a loop
for this case.
The mtd_oob_buf struct is no longer needed, nor is "erase_info_t".
Error messages for the new libmtd calls reflect the style found in
flash_erase.
Tested with nandsim and with NAND chips up to 4GB in size (I don't have
a device that truly requires 64-bit addressing yet).
