Somehow I do not see below errors on compilation:
drivers/mtd/nand/omap2.c: In function 'omap_wait':
drivers/mtd/nand/omap2.c:543: error: 'jiffies' undeclared (first use in this
function)
drivers/mtd/nand/omap2.c:543: error: (Each undeclared identifier is reported
only once
drivers/mtd/nand/omap2.c:543: error: for each function it appears in.)
drivers/mtd/nand/omap2.c:557: error: implicit declaration of function
'time_before'

But still including 'linux/jiffies.h'.

Below is the patch.
