The series is based on top of: https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/log/?h=endpoint Hello all, This series cleans up the hardware description for PCI endpoint BARs. The problems with the existing hardware description: -The documentation is lackluster. -Some of the names are confusingly similar, e.g. fixed_64bit and fixed_size, even though these are for completely unrelated things. -The way that the BARs are defined in the endpoint controller drivers is messy, because the left hand side is not a BAR, so you can mark a BAR as e.g. both fixed size and reserved. This series tries to address all the problems above. Personally, I think that the code is more readable, both the endpoint controller drivers, but also pci-epc-core.c.
Thank you for cleaning this up! FWIW: Reviewed-by: Kishon Vijay Abraham I <kishon@xxxxxxxxxx>
(Oh, and as you can probably guess, I will be sending out a patch series that adds BAR_RESIZABLE to enum pci_epc_bar_type in the coming week(s).)
