From 4186721d02b71ae943e60bbf50d3488fd5fd6adb Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 8 Feb 2015 17:11:47 +0100 Subject: bcma: add helpers bringing PCIe hosted bus up / down MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bringing PCIe hosted bus up requires operating on host-related core. Since we plan to support PCIe Gen 2 devices we should provide a helper picking the correct one (PCIE or PCIE2).
