Subject: [PATCH 10/25] usb-a926x: move reset vector to board code
Date: Mon,  1 Jan 2018 17:48:05 +0100	[thread overview]
Message-ID: <20180101164808.32371-2-sam@ravnborg.org> (raw)
In-Reply-To: <20171231083407.GA16645@ravnborg.org>

For all Calao USB boards move reset vector to board code.
Introduce two different lowlevel.c files, one
for each processor.
Include a rename to make filenames similar.
