-This add watchdog driver for broadcom 47xx device.
-It uses the ssb subsytem to access embeded watchdog device.
-
-Because the watchdog timeout is very short (about 2s), a soft timer is used
-to increase the watchdog period.
-
-Note : A patch for exporting the ssb_watchdog_timer_set will
-be submitted on next linux-mips merge. Without this patch it can't 
-be build as a module.

@@ -1,183 +0,0 @@
-the current ssb irq setup (in ssb_mipscore_init) have some problem :
-it configure some device on some irq without checking that the irq is not taken by an other device.
-
-For example in my case PCI host is on irq 0 and IPSEC on irq 3.
-The current code :
-- store in dev->irq that IPSEC irq is 3+2
-- do a set_irq 0->3 on PCI host
-
-But now IPSEC irq is not routed anymore to the mips code and dev->irq is wrong. This cause problem described in [1].
-
-This patch try to solve the problem by making set_irq configure the device we want to take the irq on the shared irq0.
-The previous example become :
-- store in dev->irq that IPSEC irq is 3+2
-- do a set_irq 0->3 on PCI host :
-  - irq 3 is already taken by IPSEC. do a set_irq 3->0 on IPSEC
-
-
-I also added some code to print the irq configuration before and after irq setup to allow easier debugging. And I add extra checking in ssb_mips_irq to report device without irq or device with not routed irq.
