*	mcb: Fix an error handling path in 'chameleon_parse_cells()'	Christophe JAILLET	2017-08-31	1	-2/+4
\| \| \| \| \| \| \| \| \| \| \| \| \|	If 'chameleon_get_bar()' fails, we will return 0, which mean success. We should return the corresponding error code instead. Remove the useless initialisation of 'ret' which was hiding the issue. (if 'ret' is not set, gcc generates a warning ("warning: ‘ret’ may be used uninitialized in this function")) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Johannes Thumshirn <jthumshirn@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
*	mcb: fix compiler warning logical-op in mcb-parse.c	Michael Moese	2016-11-15	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	The expression was clearly wrong, the logical AND of expressions must be changed to a logical OR.

*	mcb: Added bar descriptor support for non PCI bus MCB carrier	Andreas Werner	2016-08-31	1	-14/+112
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	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: Fixed bar number assignment for the gdd	Andreas Werner	2016-05-03	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \|	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.

*	mcb: export bus information via sysfs	Johannes Thumshirn	2016-05-03	1	-10/+5
\| \| \| \| \| \| \| \| \| \|	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.

*	drivers: Introduce MEN Chameleon Bus	Johannes Thumshirn	2014-02-28	1	-0/+159
	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.
