2016-04-11arc: Add virt_to_phys() stubAlexey Brodkin
Commit cf7c93cdd755 "usb: ehci: Implement V2P mapping" introduced usage of virt_to_phys() in ehci-hcd. Since there was no implementation of virt_to_phys() for ARC compilation of the ehci-generic driver failed. This change adds virt_to_phys() stub for ARC so now USB driver for AXS101 board could be built again.

2015-11-18arc: add stubs for map_physmem() and unmap_physmem()Alexey Brodkin
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>
2014-02-07arc: add architecture header filesAlexey Brodkin
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".
