Dear Robin,

Our target doesn't have a 32 KHz crystal, and the WDT (DENX) works OK.
Out target MPC855T uses only a 50MHz oscillator. The u-boot and Linux
configuration is the same as the TQM8xx, we just added:
#define CONFIG_8XX_GCLK_FREQ 50000000 in the u-boot configuration.
All our applications register with the WDT and it works OK.
Best regards,
Eli Brin
