Hello.
drivers/fmc is going to be removed from the official kernel (removal
is queued by Linus Walleij, with approval by fmc authors).
So this patch should be dropped.

This is a PCI driver that registers AMBA devices for the range of
supported devices. It is currently used by STA2X11, which exports
AMBA peripherals under PCIe. The original AMBA drivers work with no
changes or minimal ones.

The sta2x11 I/O Hub is a bridge from PCIe to AMBA. It reuses a number
of amba drivers and needs to activate core bus support.

The SP805 driver is only used by the Spear machines, and uses
writel_relaxed, which is not available on all architectures.
The dependency from CONFIG_ARM avoids compilation problems under
randomconfig when CONFIG_ARM_AMBA is enabled for x86 builds.

Hello Peter and maintainers.
I wonder what are the plans for the branch x86/amba, part of the tip
repository. Of the 7 patches in that branch, 2 are already upstream
and the other 5 rebase perfectly (only conflicts are in the header

Thank you Lars for you constructive attitude.
