Remove that restriction.
I'd prefer that this patch does not go in standalone. The intent for the MIPS
Boston board is that this driver is enabled for MIPS by this patch:
https://patchwork.kernel.org/patch/9794361/
But not until after earlier patches in that series fix issues with the driver:
https://patchwork.kernel.org/patch/9794355/
https://patchwork.kernel.org/patch/9794357/
https://patchwork.kernel.org/patch/9794359/
That has been held up by disagreement about whether the driver should be using
0-3 or 1-4 for hardware IRQ numbers, sadly, despite the driver already being
in tree & clearly broken, and my series not changing which the driver uses...
In any case, I don't really mind if people would rather remove the
architecture restrictions than just add MIPS, but I'd prefer this doesn't go
in until the rest of my series since without at least patch 1 of my seres this
will lead to various WARN()s on Boston boards.
Not with qemu, at least not yet.
from the exchange, it doesn't look like that is going to be resolved anytime
soon.
Ok, I'll hold back with adding mips/boston to my qemu tests. Too bad.
Hope this is going to be resolved before qemu and/or platform support
for boston falls apart.
Makes me wonder - is there a way to add initrd support for the platform ?
Guenter
Thanks,
Paul

Say 'Y' here if you want kernel to support the Xilinx AXI PCIe
Host Bridge driver.
