The R-Car Gen 2 PCIe driver provides PCIe host support for
Renesas R-Car Gen2 platforms. To increase hardware support enable
the driver in the shmobile_defconfig multiplatform configuration.

Hmm, I'm not sure why the option has GEN2 -- the driver claims support for
R8A7779 as well as R8A779x. Probably the option should be renamed.

Technically, you are correct. However, whilst the driver does support R8A7779, that device only supports 32-bit accesses over the PCIe bus so it's only useful for custom cards, not off-the-shelf PCIe cards.

It seems to me that dropping GEN2 from the config option may be a good idea.
But I believe that conversation is orthogonal to enabling the driver
in the defconfig. At this stage I plan to apply this patch.

I have queued up this change.
