From d23ee5de2233d2f200dc15bf4a7669599c2b2014 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Thu, 11 Aug 2016 22:45:55 +0200 Subject: mainboard: Clean up boot_option/reboot_bits in cmos.layout Since commit 3bfd7cc (drivers/pc80: Rework normal / fallback selector code) the reboot counter stored in `reboot_bits` isn't reset on a reboot with `boot_option = 1` any more. Hence, with SKIP_MAX_REBOOT_CNT_CLEAR enabled, later stages (e.g. payload, OS) have to clear the counter too, when they want to switch to normal boot. So change the bits to (h)ex instead of (r)eserved. To clarify their meaning, rename `reboot_bits` to `reboot_counter`. Also remove all occurences of the obsolete `last_boot` bit that have sneaked in again since 24391321 (mainboard: Remove last_boot NVRAM option).
