v13: 24jan2022
 - v12 erroneously omitted step 6 of bios-tables-test.c, this
   has step 6 included.
 - No other changes to v12.

v12: 10jan2022
 - Converted macros in build_erst() to uppert to follow coding
   style, as pointed out by Michael Tsirkin.
 - And few items to help further simplify build_erst().

v11: 15dec2021
 - Simplified build_erst() via feedback from Michael Tsirkin
 - Addressed additional feedback from Ani Sinha

v10: 9dec2021
 - Addressed additional feedback from Ani Sinha

v9: 2dec2021
 - Addressed feedback from Ani Sinha

v8: 15oct2021
 - Added Kconfig option for ERST, per Ani Sinha
 - Fixed patch ordering, per Ani

v7: 7oct2021
 - style improvements, per Igor
 - use of endian accessors for storage header, per Igor
 - a number of optimizations and improvements, per Igor
 - updated spec for header, per Igor
 - updated spec for rst format, per Michael Tsirkin
 - updated spec for new record_size parameter
   Due to changes in the spec, I am not carrying the
   Acked-by from Ani Sinha.
 - changes for and testing of migration to systems with
   differing ERST_RECORD_SIZE

v6: 5aug2021
 - Fixed compile warning/error, per Michael Tsirkin
 - Fixed mingw32 build error, per Michael
 - Converted exchange buffer to MemoryBackend, per Igor
 - Migrated test to PCI, per Igor
 - Significantly reduced amount of copying, per Igor
 - Corrections/enhancements to acpi_erst.txt, per Igor
 - Many misc/other small items, per Igor

v5: 30jun2021
 - Create docs/specs/acpi_erst.txt, per Igor
 - Separate PCI BARs for registers and memory, per Igor
 - Convert debugging to use trace infrastructure, per Igor
 - Various other fixups, per Igor

v4: 11jun2021
 - Converted to a PCI device, per Igor.
 - Updated qtest.
 - Rearranged patches, per Igor.

v3: 28may2021
 - Converted to using a TYPE_MEMORY_BACKEND_FILE object rather than
   internal array with explicit file operations, per Igor.
 - Changed the way the qdev and base address are handled, allowing
   ERST to be disabled at run-time. Also aligns better with other
   existing code.

v2: 8feb2021
 - Added qtest/smoke test per Paolo Bonzini
 - Split patch into smaller chunks, per Igor Mammedov
 - Did away with use of ACPI packed structures, per Igor Mammedov

v1: 26oct2020
 - initial post
