* arc: add stubs for map_physmem() and unmap_physmem()Alexey Brodkin2015-11-181-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now there was no need in those stubs. But since following commit compilation of U-Boot on ARC is broken: ------------------------>8---------------------- commit 7861204c9af7fec1ea9b41541c272516235a6c93 Author: Stephen Warren <swarren@wwwdotorg.org> Date: Sat Oct 3 13:56:46 2015 -0600 itest: make memory access work under sandbox itest accesses memory, and hence must map/unmap it. Without doing so, it accesses invalid addresses and crashes. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Reviewed-by: Simon Glass <sjg@chromium.org> ------------------------>8---------------------- That's because CMD_ITEST is enabled by default in common/Kconfig and now map_physmem()/unmap_physmem() is used there. So this patch adds missing stubs for ARC. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Reviewed-by: Simon Glass <sjg@chromium.org> Cc: Stephen Warren <swarren@wwwdotorg.org>
* arc: add architecture header filesAlexey Brodkin2014-02-071-0/+218
These are header files used by ARC700 architecture. Also note that "arch-arc700/hardware.h" is only required for compilation of "designware_i2c" driver which refers to "asm/arch/hardware.h". It would be good to fix mentioned driver sometime soon but it will cause changes in ARM board configs that use "designware_i2c".
