Hi,

This series carries forward the effort to add Kselftest for PCI Endpoint
Subsystem started by Aman Gupta [1] a while ago. I reworked the initial version
based on another patch that fixes the return values of IOCTLs in
pci_endpoint_test driver and did many cleanups. Since the resulting work
modified the initial version substantially, I took over the authorship.

This series also incorporates the review comment by Shuah Khan [2] to move the
existing tests from 'tools/pci' to 'tools/testing/kselftest/pci_endpoint' before
migrating to Kselftest framework. I made sure that the tests are executable in
each commit and updated documentation accordingly.

Changes in v4:

* Dropped the BAR fix patches and submitted them separately:
  https://lore.kernel.org/linux-pci/20241231130224.38206-1-manivannan.sadhasivam@linaro.org/
* Rebased on top of pci/next 9e1b45d7a5bc0ad20f6b5267992da422884b916e

Changes in v3:

* Collected tags.
* Added a note about failing testcase 10 and command to skip it in
  documentation.
* Removed Aman Gupta and Padmanabhan Rajanbabu from CC as their addresses are
  bouncing.

Changes in v2:

* Added a patch that fixes return values of IOCTL in pci_endpoint_test driver
* Moved the existing tests to new location before migrating
* Added a fix for BARs on Qcom devices
* Updated documentation and also added fixture variants for memcpy & DMA modes
