[PATCH v2 0/6] ARM: dts: Enable ramoops for Rainier and Tacoma

Hi,

We're looking to improve our crash data capture for the BMC on some IBM
platforms. This small series enables ramoops for Rainier and Tacoma.

v2 fixes an address overlap bug for Tacoma in v1, which was caused by a node vs
reg mismatch of one of the other reserved memory regions. v2 contains a several
cosmetic cleanups for both the Tacoma and Rainier reserved memory regions
before enabling ramoops in the final two patches. The geometry of the rings has
changed from v1; the slot sizes have been doubled, reducing the captured crash
count from 32 to 16 (32 seemed like overkill and we could trade that for more
space in each slot).

v1 can be found here:

Please review.

Andrew
