[U-Boot] Watchdog support for ppc4xx

Hi,

I have a question about watchdog support for PPC_4xx. When I define CONFIG_WATCHDOG in canyonlands.h, I get an error when building cpu_init.c. The error code reads:

{standard input}: Assembler messages:

{standard input}:133: Error: unsupported relocation against tcr

{standard input}:141: Error: unsupported relocation against tcr

{standard input}:146: Error: unsupported relocation against tsr

{standard input}:154: Error: unsupported relocation against tsr

make[1]: *** [cpu_init.o] Error 1

Shouldn't this work? Also I would like to determine in u-boot if a reset was caused by the watchdog timer using the TSR WRS field. If it was reset by the watchdog we will boot into a failsafe partition to protect against system update errors.

Has anyone done something like this?

Thanks
