From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stefan Roese Date: Fri, 10 Mar 2017 14:50:06 +0100 Subject: [U-Boot] [PATCH 3/3] arm: bootm: Add dm_remove_devices_flags() call to announce_and_cleanup() In-Reply-To: <20170310135006.14673-1-sr@denx.de> References: <20170310135006.14673-1-sr@denx.de> Message-ID: <20170310135006.14673-3-sr@denx.de> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This patch adds a call to dm_remove_devices_flags() to announce_and_cleanup() so that drivers that have one of the removal flags set (e.g. DM_FLAG_ACTIVE_DMA_REMOVE) in their driver struct, may do some last-stage cleanup before the OS is started.
