intel: Correct MMIO related ACPI table settings
Several of the intel platforms define the region reserved for PCI memory resources in a location where it overlaps with the MMIO (MCFG) region. Using the memory map from mohon_peak as an example: 0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES 1. 0000000000001000-000000000009ffff: RAM 2. 00000000000a0000-00000000000fffff: RESERVED 3. 0000000000100000-000000007fbcffff: RAM 4. 000000007fbd0000-000000007fbfffff: CONFIGURATION TABLES 5. 000000007fc00000-000000007fdfffff: RESERVED 6. 00000000e0000000-00000000efffffff: RESERVED 7. 00000000fee00000-00000000fee00fff: RESERVED 8. 0000000100000000-000000017fffffff: RAM The ACPI table describing the space set aside for PCI memory (not to be confused with the MMIO config space) is defined as the region from BMBOUND (the top of DRAM below 4GB) to a hardcoded value of 0xfebfffff. That region would overlap the MMIO region at 0xe0000000-0xefffffff. For rangeley the upper bound of the PCI memory space should be set to 0xe0000000 - 1. The MCFG regions for several of the affected chipsets are: rangeley 0xe0000000-0xefffffff baytrail 0xe0000000-0xefffffff haswell 0xf0000000-0xf3ffffff sandybridge 0xf8000000-0xfbffffff TEST = intel/mohonpeak and intel/bayleybay.
