Hello:

Just wanted to let folks know that we added support for the new nrf52 DK. The 
BSP is in hw/bsp/nrf52dk. If you have exisiting targets using either the 
nrf51dk or nrf52pdk it should be easy to copy them and replace the bsp with the 
nrf52dk:

newt target copy my_old_nrf52pdk_target my_new_nrf52dk_target
newt target set my_new_nrf52dk_target bsp=hw/bsp/nrf52dk

Aside from fixing a number of errata, one of the big fixes was that now it is 
possible to address all of the RAM as data ram. The nrf52 chips on the Preview 
Development kits could only access 32K of the 64K as data ram; the other 32K 
was code ram. This was not a big deal unless you want to DMA from memory; you 
can only use data ram.

Anyway, please give it a spin. If there are any issues please let me know.

Enjoy!
