384 1 e 4 boot_option
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).

mb/*/*: Remove rtc nvram configurable baud rate There have been discussions about removing this since it does not seem to be used much and only creates troubles for boards without defaults, not to mention that it was configurable on many boards that do not even feature uart. It is still possible to configure the baudrate through the Kconfig option.

i945: Enable changing VRAM size On i945 the vram size is the default 8mb. It is also possible to set it 1mb or 0mb hardcoding the GGC register in early_init.c The intel documentation on i945, "Mobile Intel® 945 Express Chipset Family datasheet june 2008" only documents those three options. They are set using 3 bits. The documententation also makes mention of 4mb, 16mb, 32mb, 48mb, 64mb but not how to set it. The other non documented (straight forward) bit combinations allow to change the VRAM size to those other states. What this patch does is: - add those undocumented registers with their respective vram size to the i945 NB code; - make this a cmos option on targets that have this northbridge. TEST: build, flash to target, set cmos as desired and boot linux. On Debian it can be found using "dmesg | grep stolen". NOTE: dmesg message about reserved vram are quite different depending on linux version Change-Id: Ia71367ae3efb51bd64affd728407b8386e74594f Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/14819 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
