From 262e1eaafabf32d33a9fa0b03b3c8ea426c5ae1b Mon Sep 17 00:00:00 2001 From: Aurelien Jarno Date: Mon, 3 Sep 2012 22:47:03 +0200 Subject: pflash_cfi01: fix vendor specific extended query pflash_cfi01 announces a version number of 1.1, which implies "Protection Register Information" and "Burst Read information" sections, which are not provided. Decrease the version number to 1.0 so that only the "Protection Register Information" section is needed. Set the number of protection fields (0x3f) to 0x01, as 0x00 means 256 protections field, which makes the CFI table bigger than the current implementation, causing some kernels to fail to read it.
