[U-Boot] [PATCH] mtd: Add _LARGE to MTD_MAX_*_ENTRIES

[Scott Wood]

This makes the names match current Linux source, and resolves
a conflict between
http://patchwork.ozlabs.org/patch/280488/
and
http://patchwork.ozlabs.org/patch/284513/

The former was posted first and is closer to matching Linux, but unlike
Linux it does not add _LARGE to the names.  The second adds _LARGE to
one of the names, and depends on it in a subsequent patch
(http://patchwork.ozlabs.org/patch/284512/).

I do wish this just used ARRAY_SIZE(), though. :-P
