v2:
- drop test related patches, they will be sent as a separate series
- fix bios_loader pointer initialization ordering when using TPM1.2
- extend commit message of [1/35] and add extra comment about
table length patching
Highlights:
* drop pointer arithmetic in ACPI tables code
* use endian agnostic API
* simplifies review of tables. /in most cases just line by line comparision
with spec/
Series replaces build_header() with acpi_init_table()/acpi_table_composed()
API that hides pointer/offset arithmetic from user, to prevent
errors caused by it [1].
While doing above, it was necessary to split table header from
packed structure that was describing the table, which is
counter-productive since it still leaves packed structure drawbacks.
So that sort of forced me to rewrite tables that were composed with
help of packed structures to preferred build_append_int_noprefix() API.
In cases where refactoring to build_append_int_noprefix() was small,
it was squashed with acpi_init_table()/acpi_table_composed() patch.
Conversion reduced code size quite a bit despite me adding doc comments
for every table row.
