From: Harald Krapfenbauer Harald.Krapfenbauer@bluetechnix.at
The tinyboards like to run at a little lower voltage than the default, and they prefer to boot over the network. For the latter, extend the common code a little to make this easier.
Also fix the cm-bf527 env sector size while we're in here to reflect the flash that is actually in use.
