Matt and Kurmar:
I performed name-cleanup in the driver.
Moreover, I tested this driver with PowerPC405GPr(Sycamore)
in addition to PowerPC440GP(ebony)/MPC8555(MPC8555-CDS).
This driver consist of two patches as follows:
1) Architecture specific part(booke_wdt-arch.patch)
This is the architecture specific part of the driver.
It contains WDT exception handlers
and kernel command line processing
routines.
2) Device driver part(booke_wdt-drv.patch)
This is the core of this WDT
driver.
At first, I post the architecture specific part with this mail.
Please apply.
Regards,

Out of interest how did you test this? If I find some time I will test =20=
it on an e500 system, just havent given much thought on how to test the =20=
watchdog though.

I tested the WDT driver with folowing test programs:
1) API test program which tests ioctl commands.
2) Test program which tests the behavior of the driver when
system hung up due to making interrupt disabled(MSR[EE]=0 case).
This test program is made as a kernel module.
Shall I send these programs off-list?

Matt,Kurmar and Josh:
I performed minor cleanups which Josh pointed out.
It has been fine-tuned that it suits current linux-2.6.11(linus-tree).
（These changes has been performed on architecture specific part.）.
I tested the driver on PowerPC440GP(ebony) again and I confirmed
that the driver work.
At first, I post the architecture specific part with this mail.
Please apply.
Regards,
