So far we had only MIPS devices with serial flash connected to the SoC's ChipCommon. ARM devices got a separated SPI controller and weere using standard SPI drivers. This has changed with the wireless SoC BCM47189B0. It's ARM based but has serial flash attached just like older devices. This allows using existing driver with these devices.

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

supports:
|

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.
