Currently it is not possible to have a kernel with built-in MCB attached
devices. This results out of the fact that mcb-pci requests PCI BAR 0, then
parses the chameleon table and calls the driver's probe function before
releasing BAR 0 again. When building the kernel with modules this is not a
problem (and therefore it wasn't detected by my tests yet).A solution is to only remap the 1st 0x200 bytes of a Chameleon PCI device.
0x200 bytes is the maximum size of a Chameleon v2 Table.Also this patch stops disabling the PCI device on successful registration of MCB
devices.Signed-off-by: Johannes Thumshirn

Add support for MCB over PCI devices. Both PCI attached on-board Chameleon FPGAs
as well as CompactPCI based MCB carrier cards are supported with this driver.Signed-off-by: Johannes Thumshirn

The MCB (MEN Chameleon Bus) is a Bus specific to MEN Mikroelektronik
FPGA based devices. It is used to identify MCB based IP-Cores within
an FPGA and provide the necessary framework for instantiating drivers
for these devices.Signed-off-by: Johannes Thumshirn
