This header was renamed to rawnand.h in Linux.
The following is the corresponding commit in Linux.

mtd: nand: Rename nand.h into rawnand.h
We are planning to share more code between different NAND based
devices (SPI NAND, OneNAND and raw NANDs), but before doing that
we need to move the existing include/linux/mtd/nand.h file into
include/linux/mtd/rawnand.h so we can later create a nand.h header
containing all common structure and function prototypes.

In old days, the MTD subsystem in Linux had debug facility like
DEBUG(MTD_DEBUG_LEVEL1, ...).
They were all replaced with pr_debug() until Linux 3.2. See Linux
commit 289c05222172 ("mtd: replace DEBUG() with pr_debug()").
U-Boot still uses similar macros. Covert all of them for easier sync.
Done with the help of Coccinelle.
The semantic patch I used is as follows:
// <smpl>
@@
expression e1, e2;
@@
-MTDDEBUG(e1, e2)
+pr_debug(e2)
@@
expression e1, e2;
@@
-MTDDEBUG(e1, e2,
+pr_debug(e2,
...)
// </smpl>

Updates the NAND code to match Linux v4.6. The previous sync was from
Linux v4.1 in commit d3963721d9.
Note that none of the individual NAND drivers tracked Linux closely
enough to be synced themselves, other than manually applying a few
cross-tree changes.

These functions are part of the Linux 4.6 sync. They are being added
before the main sync patch in order to make it easier to address the
issue across all NAND drivers (many/most of which do not closely track
their Linux counterparts) separately from other merge issues.

[backport from linux commit 02f8c6aee8df3cdc935e9bdd4f2d020306035dbe]
This patch merges the BCH ECC algorithm from the 3.0 Linux kernel.
This enables U-Boot to support modern NAND flash chips that
require more than 1-bit of ECC in software.
