Subject: [PATCH 04/14] bcma: add SOC bus
Subject: [PATCH 04/22] bcma: add SOC bus
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This patch adds support for using bcma on an embedded bus. An embedded
system like the bcm4716 could register this bus and it searches for the
bcma cores then.
This patch adds support for using bcma on a Broadcom SoC as the system
bus. An SoC like the bcm4716 could register this bus and use it to
searches for the bcma cores and register the devices on this bus.
BCMA_HOSTTYPE_NONE was intended for SoCs at first but BCMA_HOSTTYPE_SOC
is a better name.
