096eb844e7 mcb: Fixed bar number assignment for the gdd
commit f75564d343 upstream.

The bar number is found in reg2 within the gdd. Therefore
we need to change the assigment from reg1 to reg2 which
is the correct location.

07792c7e10 drivers: mcb: Fix build error discovered by 0-day bot
Make mcb depend on HAS_IOMEM and mcb-pci depend on PCI. This fixes build errors
discovered by the 0-day kernel build testing system.

    drivers: Introduce MEN Chameleon Bus

The above commit used "default m" which is wrong.  New drivers
should never be globally enabled with "default y/m".  Whether
this driver makes sense to build on ARM is an independent issue.

Here we delete the "default m" line, which is the equivalent of
"default n".

3764e82e51 drivers: Introduce MEN Chameleon Bus
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.
