mcb: Added bar descriptor support for non PCI bus MCB carrier

2016-08-31T11:16:24+00:00

Added support for the bar descriptor. This type is used for FPGAs
connect to the LPC or to a non PCI bus.

The Bar descriptor could have a maximum of 6 BARs. Each of the
devices within the FPGA could be mapped to a different BAR.
The BAR descriptor is comparable to the PCI header.

mcb: export bus information via sysfs

2016-05-03T22:07:35+00:00

Export information about the bus stored in the FPGA's header to userspace via
sysfs, instead of hiding it in pr_debug()s from everyone.

mcb: mcb-pci: Only remap the 1st 0x200 bytes of BAR 0

2015-01-09T23:46:37+00:00

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.

mcb: Add PCI carrier for MEN Chameleon Bus

2014-02-28T23:47:12+00:00

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.

drivers: Introduce MEN Chameleon Bus

2014-02-28T23:36:37+00:00

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.
