PS1, Line 48: int tseg_size = 128 * KiB * (1 << (tseg >> 1));
            : 		tom -= tseg_size;
> Shouldn't this be changed too? What's the purpose of integer type here? (And above too)

If anything, this belongs to a follow-up.

PS1, Line 76: uintptr_t top_of_ram = ALIGN_DOWN(northbridge_get_tseg_base(), 4*MiB);
            : 	return top_of_ram;
> Can it fit in one line?

+1, there are other occurrences in other Intel platforms. Could be done in a follow-up.

PS1, Line 9: 	return ((sdram_max_addressable_mb() - FB_SIZE_MB) << 20UL);
nit: Outer set of parentheses is now unnecessary
