From d77c7ac47e4ea750cc13c2f0ecc037ab7afa7964 Mon Sep 17 00:00:00 2001 From: Philippe De Muyter Date: Tue, 10 Aug 2010 16:54:52 +0200 Subject: Fix printing & reading of 16-bit CFI device identifiers Fix reading and printing of CFI flashes 16-bit devices identifiers Nowadays CFI flashes have a 16-bit device identifier. U-boot still print them and read them as if they were only 8-bit wide. Fix that.
