[IA64-SGI] Altix patch to tiocx, add subsys_initcall
This patch fixes an ordering issue between the init code for the tiocx bus driver and tiocx-related device drivers. Also adds a new brick to the list of known FPGA bricks. Signed-off-by: Bruce Losure <blosure@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
