2016-10-04nb/gm45: allow use of 352M preallocated ram for igdArthur Heymans
The datasheets on gm45: "Mobile IntelĀ® 4 Series Express Chipset Family" mention the possibility of having 352M ram preallocated for the integrated graphic device. This only worked fine if the amount of ram in the system was 3GB or less. When 4G or more is installed, memory is remapped to create a 1GB large pci mmio hole which is not enough and creates conflicts when 352M vram is used. This patch increases the pci mmio hole size on Lenovo x200 to allow 352M vram to work. TEST: build and flash on target with 4GB ram or more, use nvramtool to set gfx_uma_size to 352M and reboot.

2016-08-17mainboard: Clean up boot_option/reboot_bits in cmos.layoutNico Huber
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).

2016-06-04gm45: enable setting all vram sizes from cmosArthur Heymans
Setting the size of the preallocated memory for the igd is done using a cmos parameter, gfx_uma_size. This was limited to a subset of all available sizes, that were already implemented elsewhere in the northbridge code. What this does is change the cmos parameter to 4 bits instead of 3 bits to accomodate all vram sizes. It also adds a sane default of 32mb that already was in place. The northbridge code that reads this cmos parameter is also changed for this new cmos settings. 352M is disabled since it causes issues on systems with 4GB or more ram. TEST: Build, flash target. Clear cmos by corrupting the checksum (nvramtool -c something). Set a desired value in gfx_uma_size using nvramtool. "dmesg | grep stolen" to see what is actually allocated.

2016-06-01drivers/lenovo: Add hybrid graphics driverPatrick Rudolph
Add a universal hybrid graphics driver compatible with all supported lenovo devices. Hybrid graphics allows to connect the display panel to either of one GPUs. As there are only two GPUs one GPIO needs to be toggled. In case the discrete GPU is activated the panel is routed to it. On deactivation the panel is routed to the integrated GPU. On lenovo laptops the dGPU is always connected to PEG10 and it is save to disable the PEG slot on dGPU deactivation. Use common gpio.c for southbridge I82801IX. Tested on Lenovo T520 using Nvidia NVS 5200m. Removed Lenovo T430s from the list of supported devices, as the T430s only supports "muxless Optimus".

It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.
