From 0e16872572692e0d102b082a8d7297c4065a7ea0 Mon Sep 17 00:00:00 2001 From: Igor Romanov Date: Thu, 24 Sep 2020 13:12:20 +0100 Subject: [PATCH] common/sfc_efx/base: add efsys API to find a memory BAR Function control window lookup needs memory BARs handles to search Xilinx capabilities tables. Define an API to get a memory BAR handle by a PCIe device handle and BAR index.
