Subject: [PATCH 0/4] ARM: footbridge: cleanups

From: Arnd Bergmann <arnd@...db.de>

I had an older patch to remove the addin mode for footbridge,
which nobody is using any more, and I found a few other small
cleanups that are worth doing here.

Footbridge is now the only platform with a custom __virt_to_bus()
for ISA DMA, and a custom phys_to_dma() for PCI devices. Both
just add a fixed offset, so there is probably a better way
of doing the same without a custom helper function.

  ARM: footbridge: remove addin mode
  ARM: footbridge: remove leftover from personal-server
  ARM: footbridge: move isa-dma support into footbridge
  ARM: footbridge: limit CONFIG_ISA to CATS
