set vram on gm45 to 352M

This patch enables all vram sizes and sets the default to 352M for
libreboot.
Normally users have to clear their vram for this to happen. using
"nvram -c random"

But there a 2 better option:
coreboot provides to always load the defaults in its menuconfig
update the flashscript to reset cmos

sizes from cmos + +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. + +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. + +Change-Id: Ia6479d03f1abe6d0c94bd7264365505e8f8eaeec +Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> + +diff --git a/src/mainboard/lenovo/t400/cmos.default b/src/mainboard/lenovo/t400/cmos.default +index 98ce970..5cf3e63 100644 +--- a/src/mainboard/lenovo/t400/cmos.default ++++ b/src/mainboard/lenovo/t400/cmos.default +@@ -13,4 +13,5 @@ sticky_fn=Disable + power_management_beeps=Enable + low_battery_beep=Enable + sata_mode=AHCI +-hybrid_graphics_mode=Integrated Only +\ No newline at end of file ++hybrid_graphics_mode=Integrated Only ++gfx_uma_size=32M +\ No newline at end of file +diff --git a/src/mainboard/lenovo/t400/cmos.layout b/src/mainboard/lenovo/t400/cmos.layout +index 8e642f8..881bc02 100644 +--- a/src/mainboard/lenovo/t400/cmos.layout ++++ b/src/mainboard/lenovo/t400/cmos.layout +@@ -76,12 +76,11 @@ entries + 939 1 e 1 low_battery_beep + 940 1 e 1 uwb + +-# coreboot config options: northbridge +-941 3 e 11 gfx_uma_size +- + # coreboot config options: graphics + 944 2 e 12 hybrid_graphics_mode +-#946 6 r 0 unused ++ ++# coreboot config options: northbridge ++946 4 e 11 gfx_uma_size + + # coreboot config options: EC + 952 8 h 0 volume +@@ -130,12 +129,19 @@ enumerations + 9 1 Primary + 10 0 AHCI + 10 1 Compatible +-11 0 32M +-11 1 48M +-11 2 64M +-11 3 128M +-11 5 96M +-11 6 160M ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M ++11 12 352M + 12 0 Integrated Only + 12 1 Discrete Only + 12 2 Switchable +diff --git a/src/mainboard/lenovo/x200/cmos.default b/src/mainboard/lenovo/x200/cmos.default +index ac9f96d..1d7b420 100644 +--- a/src/mainboard/lenovo/x200/cmos.default ++++ b/src/mainboard/lenovo/x200/cmos.default +@@ -13,3 +13,4 @@ sticky_fn=Disable + power_management_beeps=Enable + low_battery_beep=Enable + sata_mode=AHCI ++gfx_uma_size=32M +\ No newline at end of file +diff --git a/src/mainboard/lenovo/x200/cmos.layout b/src/mainboard/lenovo/x200/cmos.layout +index 931cb4a..7db5347 100644 +--- a/src/mainboard/lenovo/x200/cmos.layout ++++ b/src/mainboard/lenovo/x200/cmos.layout +@@ -77,10 +77,10 @@ entries + 940 1 e 1 uwb + + # coreboot config options: northbridge +-941 3 e 11 gfx_uma_size +- + 944 8 h 0 volume + ++952 4 e 11 gfx_uma_size ++ + # coreboot config options: check sums + 984 16 h 0 check_sum + #1000 24 r 0 unused +@@ -125,12 +125,19 @@ enumerations + 9 1 Primary + 10 0 AHCI + 10 1 Compatible +-11 0 32M +-11 1 48M +-11 2 64M +-11 3 128M +-11 5 96M +-11 6 160M ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M ++11 12 352M + + # ----------------------------------------------------------------- + checksums +diff --git a/src/mainboard/roda/rk9/cmos.layout b/src/mainboard/roda/rk9/cmos.layout +index f567b97..74fef63 100644 +--- a/src/mainboard/roda/rk9/cmos.layout ++++ b/src/mainboard/roda/rk9/cmos.layout +@@ -70,9 +70,9 @@ entries + 984 16 h 0 check_sum + + # coreboot config options: northbridge +-1000 3 e 10 gfx_uma_size ++1000 4 e 10 gfx_uma_size + +-#1003 21 r 0 unused ++#1004 20 r 0 unused + + # ram initialization internal data + 1024 128 r 0 read_training_results +@@ -112,13 +112,19 @@ enumerations + 8 1 Yes + 9 0 AHCI + 9 1 Compatible +-10 0 32M +-10 1 48M +-10 2 64M +-10 3 128M +-10 5 96M +-10 6 160M +- ++11 0 1M ++11 1 4M ++11 2 8M ++11 3 16M ++11 4 32M ++11 5 48M ++11 6 64M ++11 7 128M ++11 8 256M ++11 9 96M ++11 10 160M ++11 11 224M ++11 12 352M + # ----------------------------------------------------------------- + checksums + +diff --git a/src/northbridge/intel/gm45/igd.c b/src/northbridge/intel/gm45/igd.c +index 7e7bbbe..e029b7b 100644 +--- a/src/northbridge/intel/gm45/igd.c ++++ b/src/northbridge/intel/gm45/igd.c +@@ -153,10 +153,10 @@ void igd_compute_ggc(sysinfo_t *const sysinfo) + /* Graphics Stolen Memory: 2MB GTT (0x0300) when VT-d disabled, + 2MB GTT + 2MB shadow GTT (0x0b00) else. */ + if (get_option(&gfxsize, "gfx_uma_size") != CB_SUCCESS) { +- /* 0 for 32MB */ +- gfxsize = 0;
