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. |
