libmtd: support MEMERASE64
This patch is base on Kevin Cernekee's patch posted to the MTD mailing list. It adds MEMERASE64 support to the 'mtd_erase()' call. Now it first tries to use MEMERASE64, and if that is not supported, falls back to the old MEMERASE ioctl. This patch also introduces an 'offs64_ioctl' flag to the libmtd descriptor. However, we cannot initialize it in 'libmtd_open()', because we need an MTD device node, which we do not have in 'libmtd_open()'. Thus, we firs mark this flag as "uninitialized", and at the first invocation of 'mtd_erase()' we initialize it. This also means that we have to pass the limbtd descriptor to 'mtd_erase()', to save the flag value. This, in turn, requires tweaking 'mtd_erase()' users. This is not very nice, but good enough so far. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
