This patchset fixes problems while trying to allocate space for PCI
endpoint function.
The problems, and related fixups, have been found while trying to link two
renesas rcar-gen4 r8a779f0-spider devices with the vNTB endpoint
function. This platform has 2 configurable BAR0 and BAR2, with an alignment
of 1MB, and fairly small fixed BAR4 of 256B.
This was tested with
* BAR0 (1MB): CTRL+SPAD
* BAR2 (1MB): MW0
* BAR4 (256B): Doorbell
This setup is currently not supported by the vNTB EP driver and requires a
small hack. I'm working on that too.
