Re: Fwd: Gumstix Verdex not booting with NetBSD 7.0 and newer

Hi Nick,

thanks for the helping hand.

I will give it a try tomorrow. I'm further down the road after building 
several old "-current" since NetBSD 6. Gumstix seems to be the only 
Xscale-board which uses the arm32_kernel_vm_init() atm. So poking around 
without starting to read the complete Intel Xscale documentation is a 
bit difficult. But after the kernel hangs on clearing dcache I'm pretty 
sure an issue is the removed xscale_cache_clean_addr. I'm not sure were 
to add the line again for a proper patch, but my hasty modifed kernel is 
now booting further. Sadly still panics later, but progress is good ;-)
To my understanding the cache clean address is elemental for Xscale ARMs 
maybe would be a good idea to KASSERT in a nice shared place if not set?
