soc/intel/common: Use per-soc definition for BAR sizes
The various platform BARs are not always the same size across different SOCs, so use the defined size rather than a hardcoded value. This results in the following change on TGL which increased the MCHBAR size to 128K: -system 00:00: [mem 0xfedc0000-0xfeddffff] has been reserved +system 00:00: [mem 0xfedc0000-0xfedc7fff] has been reserved And fixes the following error output from the kernel: resource sanity check: requesting [mem 0xfedc0000-0xfedcdfff], which spans more than pnp 00:00 [mem 0xfedc0000-0xfedc7fff] Change-Id: I82796c2fc81dec883f3c69ae7bdcedc7d3f16c64 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/47378 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Subrata Banik <subrata.banik@intel.com>
