[PATCH v3 0/8] acpi: Some fixes for pxb support for ARM virt machine |
Date: |

This patch series adds some fixes for ARM virt machine pxb support.
1. Pass addr offset for IO, MMIO and bus number when builing crs, because
the addr_trans is needed to describe an addr resource. [1]
2. Inform guest os not to ignore the resource map generated by firmware as
the x86 default way. [2]
3. Reorder the root bridges [3] and exclude resources of extra root bridges
from main root bridge's _CRS.
4. Enable pxb for ARM virt machine by default.
5. Update expected DSDT files with the above changes and enable the pxb
unit-test.
v2->v3:
* Reorder the root bridges.
* Exclude resources of extra root bridges from main root bridge's _CRS.
v1->v2:
* Update expected DSDT files.
* Quote PCI Firmware spec as comments.
