From 142e30fcaa1c3a63a1f0baf0b802ef888a0c250b Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Tue, 14 Jul 2009 10:26:56 +0000 Subject: Use a distinct return code for SPI commands with unsupported/invalid length Some drivers support only a few combinations of read/write length and return error otherwise. Having a distinct return code for this error means we can handle it in upper layers. Corresponding to flashrom svn r653.
