+Subject: [PATCH] gm45: enable setting all vram 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.
+The northbridge code that reads this cmos parameter is
+also changed for this new cmos settings.
+
+352M is disabled since it often causes issues 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.
