Collection of DOE material, v4:
Migrate to synchronous API, create mailboxes in PCI core instead of
in drivers, relax restrictions on request/response size.
This should probably go in via the cxl tree because Dave Jiang is
basing his cxl work for the next merge window on it.
The first 6 patches are fixes, so could be applied immediately.
Thanks!
Changes v3 -> v4:
* [PATCH v4 01/17] cxl/pci: Fix CDAT retrieval on big endian
* In pci_doe_discovery(), add request_pl_le / response_pl_le variables
to avoid typecasts in pci_doe_task initializer (Jonathan)
* In cxl_cdat_read_table(), use __le32 instead of u32 for "*data"
variable (Jonathan)
* Use sizeof(__le32) instead of sizeof(u32) (Jonathan)
* [PATCH v4 03/17] cxl/pci: Handle truncated CDAT entries
* Check for sizeof(*entry) instead of sizeof(struct cdat_entry_header)
for clarity (Jonathan)
* [PATCH v4 12/17] PCI/DOE: Create mailboxes on device enumeration
* Amend commit message with additional justification for the commit
(Alexey)
* [PATCH v4 16/17] cxl/pci: cxl/pci: Simplify CDAT retrieval error path
* Newly added patch in v4 on popular request (Jonathan, Dave)
* [PATCH v4 17/17] cxl/pci: Rightsize CDAT response allocation
* Amend commit message with spec reference to the Table Access
Response Header (Ira)
* In cxl_cdat_get_length(), check for sizeof(response) instead of
2 * sizeof(u32) for clarity
