* of: consolidate definition of early_init_dt_alloc_memory_arch()Grant Likely2013-08-28
| | | | | | | Most architectures use the same implementation. Collapse the common ones into a single weak function that can be overridden. Signed-off-by: Grant Likely <grant.likely@linaro.org>
* ARC: make a copy of flat DTVineet Gupta2013-02-26
| | | | | | | | | | The flat DT (currently embedded in vmlinux) is in .init section. The unflattened/binary tree doesn't copy strings through and references them from orig flat DT - which could cause catestrohpy if of_* APIs are called post init, say from a driver which is a loadable module.

* ARC: [Review] Multi-platform image #2: Board callback InfrastructureVineet Gupta2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The orig platform code orgnaization was singleton design pattern - only one platform (and board thereof) would build at a time. Thus any platform/board specific code (e.g. irq init, early init ...) expected by ARC common code was exported as well defined set of APIs, with only ONE instance building ever. Now with multiple-platform build requirement, that design of code no longer holds - multiple board specific calls need to build at the same time - so ARC common code can't use the API approach, it needs a callback based design where each board registers it's specific set of functions, and at runtime, depending on board detection, the callbacks are used from the registry. This commit adds all the infrastructure, where board specific callbacks are specified as a "maThine description". All the hooks are placed in right spots, no board callbacks registered yet (with MACHINE_STARt/END constructs) so the hooks will not run. Next commit will actually convert the platform to this infrastructure. Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Arnd Bergmann <arnd@arndb.de> Acked-by: Arnd Bergmann <arnd@arndb.de>

* ARC: [DeviceTree] Basic supportVineet Gupta2013-02-15
This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".
