This allows us to increase compile-test coverage without having to build a kernel for MIPS. That's particularly interesting for subsystem maintainers that want to test as many drivers as possible in a single build. We also add a dependency on HAS_IOMEM in BCMA_HOST_SOC to make sure the driver is not selected when the arch does not implement IO accessors.

BCMA bus may have many versions of PCIe core. This driver

1) PCIe core working in clientmode

2) PCIe Gen 2 clientmode core

In general PCIe (Gen 2) clientmode core is required on PCIe

hosted buses. It's responsible for initialization and basic

hardware management.

This driver is also prerequisite for a hostmode PCIe core

support.

Some cheap devices have serial flash connected to the ChipCommon
|
|
instead of independent SPI controller. It requires using a separated
|
|
driver that implements ChipCommon specific interface communication.

Enabling this symbol will let bcma recognize serial flash and register
|

it as platform device.
