Rework fallback sprom support by providing different sproms for different chips. Also make it optional to use. This likely causes sprom fallback support to break on a few boards. Signed-off-by: Jonas Gorski <jogo@openwrt.org> SVN-Revision: 41942

Subject: [PATCH 01/10] MIPS: BCM63XX: move fallback sprom support into its own
|
|
unit
|
|
|
|
In preparation for enhancing it, move it into its own file. Require a
|
|
mac address to be passed as the argument to always "reserve" the mac
|
|
regardless of the inclusion state of SSB.
