From ffc7bb3857e42acab131271e485735cbf673d0f0 Mon Sep 17 00:00:00 2001 From: Andreas Werner Date: Fri, 26 Aug 2016 09:34:58 +0200 Subject: mcb: Added bar descriptor support for non PCI bus MCB carrier 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.
