This is my best try. I have test it with my old u-boot, but not with master. Do not have a bench for it. This is not very important patch. I do not find any other ONFI user in u-boot. Andrei

From: Andrei Yakimov ayakimov@iptec-inc.com Date: Mon, 18 May 2015 18:50:12 -0700 Subject: [PATCH] ONFI detect reading only first parameter page.

NAND_CMD_PARAM read only first parameter page. Need to read all 3 (as per ONFI spec) due to no error correction for this area
