2016-12-08cpu/x86: allow AP callbacks after MP initAaron Durbin
There are circumstances where the APs need to run a piece of code later in the boot flow. The current MP init just parks the APs after MP init is completed so there's not an opportunity to target running a piece of code on all the APs at a later time. Therefore, provide an option, PARALLEL_MP_AP_WORK, that allows the APs to perform callbacks.

2016-12-07PCI ops: MMCONF_SUPPORT_DEFAULT is requiredKyösti Mälkki
Doing PCI config operations via MMIO window by default is a requirement, if supported by the platform. This means chipset or CPU code must enable MMCONF operations early in bootblock already, or before platform-specific romstage entry. Platforms are allowed to have NO_MMCONF_SUPPORT only in the case it is actually not implemented in the silicon.

Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.

Avoid the inclusion of a function declaration if the argument type device_t is not defined. This was not a problem until now because the old declaration of device_t and the new one overlapped.

2016-08-03ACPI: Add code to include ATSR structure in DMAR tableWerner Zeh
DMAR tables can contain so called "Address Translation Service Reporting" (ATSR) structure. It is applicable for platforms that support Device-TLBs and describe PCI root ports that have this ability. Add code to create this ATSR structure. In addition, a function to fix up the size of the ATSR structure is added as this is a new type and using the function acpi_dmar_drhd_fixup() can lead to confusion.
