Update dts files of Cubieboard1,2 to use 1GB memory. Add a function to print the contents of the static device mapping table, 2013-12-14T00:16:08Z Ian Lepore ian@FreeBSD.org 2013-12-14T00:16:08Z urn:sha1:fbebfc5bbf87809c00980cd5110125009041430b Call initarm_lastaddr() later in the init sequence, after establishing static device mappings, rather than as the first of the initializations that a platform can hook into. This allows a platform to allocate KVA from the top of the address space downwards for things like static device mapping, and return the final "last usable address" result after that and other early init work is done. Because some platforms were doing work in initarm_lastaddr() that needs to be done early, add a new initarm_early_init() routine and move the early init code to that routine on those platforms. Make PTE_DEVICE a synonym for PTE_NOCACHE on armv4, to make it easier to share the same code on both architectures. Add new helper routines for arm static device mapping. The new code allocates kva space from the top down for the device mappings and builds entries in an internal table which is automatically used later by arm_devmap_bootstrap(). The platform code just calls the new arm_devmap_add_entry() function as many times as it needs to (up to 32 entries allowed; most platforms use 2 or 3 at most). Remove imx local devmap code and use the essentially identical common code that got moved from imx_machdep.c to arm/devmap.c. 2013-12-13T23:56:53Z Ian Lepore ian@FreeBSD.org 2013-12-13T23:56:53Z urn:sha1:08ae16c410797796cb565ea0538e5f8243c0ee2e Begin reducing code duplication in arm pmap.c and pmap-v6.c by factoring out common code related to mapping device memory into a new devmap.c file. Remove the growing duplication of code that used pmap_devmap_find_pa() and then did some math with the returned results to generate a virtual address, and likewise in reverse to get a physical address. Now there are a pair of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that. The bus_space_map() implementations are rewritten in terms of these. Move remaining code and data related to static device mapping into the new devmap.[ch] files. Emphasize the MD nature of these things by using the prefix arm_devmap_ on the function and type names (already a few of these things found their way into MI code, hopefully it will be harder to do by accident in the future).
