From 064b1f23fa507878bddca3c308e5e6034b06c998 Mon Sep 17 00:00:00 2001 From: Adam Kaufman Date: Tue, 6 Feb 2007 19:47:50 +0000 Subject: This patch is a rework of Adam Kaufman's Solaris patch * flash.h: - add a license header - add system definitions * flash_enable.c: - put io priviledge access in one single place - add includes required for Solaris. * lbtable.c, flash_rom.c, 82802ab.c: - use MEM_DEV so it works on Solaris * sst49lfxxxc.c, sharplhf00l04.c, sst_fwhub.c, 82802ab.c - drop unneeded include to sys/io.h * Makefile - adapt to Solaris specifics. Corresponding to flashrom svn r88 and coreboot v2 svn r2550.
