Subject: [PATCH v2 0/3] Parse the HEST PCIe AER and set to relevant registers

From: LeoLiuoc <LeoLiu-oc@...oxin.com>

According to the Section 18.3.2.4, 18.3.2.5 and 18.3.2.6 in ACPI SPEC
r6.5, the register value form HEST PCI Express AER Structure should be
written to relevant PCIe Device's AER Capabilities.So the purpose of the
patch set is to extract register value from HEST PCI Express AER
structures and program them into PCIe Device's AER registers. Refer to the
ACPI SPEC r6.5 for the more detailed description. This patch is an
effective supplement to _HPP/_HPX method when the Firmware does not
support the _HPP/_HPX method and can be specially configured for the AER
register of the specific device.

---

v1->v2:
- Move the definition of structure "hest_parse_aer_info" to file apei.h.

LeoLiuoc (3):
  ACPI/APEI: Add hest_parse_pcie_aer()
  PCI: Add AER bits #defines for PCIe to PCI/PCI-X Bridge
  PCI/ACPI: Add pci_acpi_program_hest_aer_params()
