2022-11-17	mb/emulation/qemu-q35: Release TSEG reserve with SMM_ASEG	Kyösti Mälkki
	If TSEG is not enabled, smm_region() should not reserve the region, so add a test for T_EN flag in ESMRAMC. For the SMM_ASEG case this moves CBMEM immediately below top-of-ram.

2021-11-10	Rename ECAM-specific MMCONF Kconfigs	Shelley Chen
	Currently, the MMCONF Kconfigs only support the Enhanced Configuration Access mechanism (ECAM) method for accessing the PCI config address space. Some platforms have a different way of mapping the PCI config space to memory. This patch renames the following configs to make it clear that these configs are ECAM-specific: - NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT - MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT - MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS - MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER - MMCONF_LENGTH --> ECAM_MMCONF_LENGTH Please refer to CB:57861 "Proposed coreboot Changes" for more details.

	Move all Q35 register definitions into the q35.h header. Note that real hardware does not have EXT_TSEG_MBYTES, because it is QEMU-specific.

2021-01-22	mb/emulation/qemu-q35: Account for TSEG	Arthur Heymans
	TSEG is located below TOLUD. The size is configured in ESMRAMC but can also be configured with "-global mch.extended-tseg-mbytes=5" command line argument. Note that the size in ESMRAMC needs to be 'invalid' (3) for this to take action. coreboot will leave TSEG at the default 1MiB. Note that even if TSEG does not end up being used, it is likely a good idea to not put anything there as if SMM gets locked down by something else it will suddenly be inaccessible.
