From 886bd33da7cfb1f6c7f3396f7146278ed02e76a7 Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Mon, 9 Apr 2012 11:41:37 +0800 Subject: [PATCH] mtd: print out the page size and oob size after parsing out the nand Some not-supported nand chips may pass the current parsing code, and get the wrong page size and oob size. Sometimes, it's hard to notice that you get the wrong values, because there is no warning or error. So it's useful to print out the page size and oob size in the end of the parsing function. We can check these values with the datasheet of the nand chip as soon as possible.
