[U-Boot] [PATCH] update nand.h to support address more than 0x80000000

[adrian wen]

Hi all,

I found a bug in nand.h which prevent UBOOT to supprt large NAND chip.

The bug description as below:
In the original implementation, we use a wrapper function in
nand.h to facilitate nand_base function usage in other files,
like cmd_nand.c, nand_util.c etc.

However, the wrapper in nand.h is using off_t which is long type.
If we pass a address like 0x80000000, which is allowed by nand_base.c,
the wrapper would recognize it as a negative num. So we would get a
huge num when this parameter get into nand_base.c

Fix it by replacing off_t to loff_t type.
