oob is unsigned char array, the cast and masking should not be needed.
btw make us into u16 type.

You can use the BIT() macro here.

Can we use devm_ functions all over the place ?
Can we avoid the double-allocation, ie. by embedding the maximum oob
sized buffer into struct mtd_logical (which might need renaming btw)
or allocating it on stack (it's likely a few bytes)?

You should stop using this (u_int) stuff unless there's a real good
reason for that (which I doubt).

Could be reduced to
struct sharpsl_nand_partition_info {
u32 start;
u32 end;
u32 magic;
u32 reserved;
};
And then have struct sharpsl_nand_partition_info *foo; and index it with
