New Revision: 256576
URL: http://svnweb.freebsd.org/changeset/base/256576
Log:
Initial commit of AR9340 switch SoC support.
This is just the chip initialisation code (for now.)
It's not linked into the main build as it requires a bunch of other code
to be tidied up and committed. But it indeed does function as advertised.
Tested:
* AR9344 SoC
Added:
head/sys/dev/etherswitch/arswitch/arswitch_9340.c (contents, props changed)
head/sys/dev/etherswitch/arswitch/arswitch_9340.h (contents, props changed)
Added: head/sys/dev/etherswitch/arswitch/arswitch_9340.c
