[coreboot] Types in E820 memory detection

[Rick van Rein]

Hello,

The INT 0x15, EAX=0xE820 function lists available memory, including a type.
Who defines those types?  Or is it simply what BIOSes happen to be doing?

I found a list of types on

http://wiki.osdev.org/Detecting_Memory_(x86)#BIOS_Function:_INT_0x15.2C_EAX_...

and would like to add a few types, like

Type 0xBAD1: BadRAM address/mask pair
Type 0xF1A5: Flash memory on the memory bus (so, NOR Flash)

and am in search for the best way to do this.

Thanks,
 -Rick
