Thread-topic: SMTC support status in latest git head.
Hi list,

Any body is aware of SMTC support status in latest git sources?. I have tried 
testing SMTC kernel for malta in qemu / OVP without any success ( emulators not 
working for 34k). 

I am trying to bring up SMTC Linux support for an mips34K based soc ( MSP71xx 
family).

While booting , kernel getting hung on calibrate loop delay. I am getting only 
one interrupt from timer. With similar smtc platform support file (  changed to 
map smp_ops structure)  2.6.24-stable branch kernel ( where latest timer 
structure introduced) boots fine.
