picoXcell is a family of femtocell devices with an ARM application processor and picoArray DSP processor array. This patch adds support for picoXcell boards to be booted using the device tree registering the VIC's, UART's and timers. v2: - cleanup empty mach headers - convert to of_platform_populate() - simplify uncompress.h - split vic node into 2 devices - add missing __initconst attributes Signed-off-by: Jamie Iles <jamie@jamieiles.com> --- .../devicetree/bindings/arm/picoxcell.txt | 23 ++++ arch/arm/Kconfig | 18 +++ arch/arm/Makefile | 1 + arch/arm/mach-picoxcell/Makefile | 3 + arch/arm/mach-picoxcell/Makefile.boot | 1 + arch/arm/mach-picoxcell/common.c | 55 ++++++++ arch/arm/mach-picoxcell/common.h | 18 +++ arch/arm/mach-picoxcell/include/mach/debug-macro.S | 35 +++++ arch/arm/mach-picoxcell/include/mach/entry-macro.S | 19 +++ arch/arm/mach-picoxcell/include/mach/gpio.h | 1 + arch/arm/mach-picoxcell/include/mach/hardware.h | 21 +++ arch/arm/mach-picoxcell/include/mach/io.h | 29 +++++ arch/arm/mach-picoxcell/include/mach/irqs.h | 25 ++++ arch/arm/mach-picoxcell/include/mach/map.h | 25 ++++ arch/arm/mach-picoxcell/include/mach/memory.h | 1 + .../mach-picoxcell/include/mach/picoxcell_soc.h | 25 ++++ arch/arm/mach-picoxcell/include/mach/system.h | 31 +++++ arch/arm/mach-picoxcell/include/mach/timex.h | 25 ++++ arch/arm/mach-picoxcell/include/mach/uncompress.h | 21 +++ arch/arm/mach-picoxcell/include/mach/vmalloc.h | 18 +++ arch/arm/mach-picoxcell/io.c | 56 ++++++++ arch/arm/mach-picoxcell/time.c | 132 ++++++++++++++++++++ 22 files changed, 583 insertions(+), 0 deletions(-) create mode 100644 Documentation/devicetree/bindings/arm/picoxcell.txt create mode 100644 arch/arm/mach-picoxcell/Makefile create mode 100644 arch/arm/mach-picoxcell/Makefile.boot create mode 100644 arch/arm/mach-picoxcell/common.c create mode 100644 arch/arm/mach-picoxcell/common.h create mode 100644 arch/arm/mach-picoxcell/include/mach/debug-macro.S create mode 100644 arch/arm/mach-picoxcell/include/mach/entry-macro.S create mode 100644 arch/arm/mach-picoxcell/include/mach/gpio.h create mode 100644 arch/arm/mach-picoxcell/include/mach/hardware.h create mode 100644 arch/arm/mach-picoxcell/include/mach/io.h create mode 100644 arch/arm/mach-picoxcell/include/mach/irqs.h create mode 100644 arch/arm/mach-picoxcell/include/mach/map.h create mode 100644 arch/arm/mach-picoxcell/include/mach/memory.h create mode 100644 arch/arm/mach-picoxcell/include/mach/picoxcell_soc.h create mode 100644 arch/arm/mach-picoxcell/include/mach/system.h create mode 100644 arch/arm/mach-picoxcell/include/mach/timex.h create mode 100644 arch/arm/mach-picoxcell/include/mach/uncompress.h create mode 100644 arch/arm/mach-picoxcell/include/mach/vmalloc.h create mode 100644 arch/arm/mach-picoxcell/io.c create mode 100644 arch/arm/mach-picoxcell/time.c
