Author: ian Date: Mon Dec 21 18:07:32 2015 New Revision: 292555 URL: https://svnweb.freebsd.org/changeset/base/292555 Log: Implement OF_decode_addr() for arm. Move most of powerpc's implementation into a new function that other platforms can share. This creates a new ofw_reg_to_paddr() function (in a new ofw_subr.c file) that contains most of the existing ppc implementation, mostly unchanged. The ppc code now calls the new MI code from the MD code, then creates a ppc-specific bus_space mapping from the results. The new arm implementation does the same in an arm-specific way. This also moves the declaration of OF_decode_addr() from ofw_machdep.h to openfirm.h, except on sparc64 which uses a different function signature. This will help all FDT platforms to set up early console access using OF_decode_addr().
