Subject: [U-Boot] [PATCH 2/5] usb: ehci: Use map_physmem in ehci-generic
Date: Wed, 27 Jan 2016 03:14:00 +0100 [thread overview]
Message-ID: <1453860843-5835-2-git-send-email-marex@denx.de> (raw)
In-Reply-To: <1453860843-5835-1-git-send-email-marex@denx.de>
Some architectures, like MIPS, require remapping of the registers.
Add the map_physmem() call to handle it.
