  • 40c6d8aee   ARM: 7022/1: allow to detect conflicting zreladdrs ... Browse Code »

    Boards used to specify zreladdr in their Makefile.boot with
    zreladdr-y := x, so conflicting zreladdrs were silently overwritten.
    This patch changes this to zreladdr-y += x, so that we end
    up with multiple words in zreladdr in such a case. We can
    detect this later and complain if necessary.

  • 49cbe7863   [ARM] pxa: add base support for Marvell's PXA168 processor line ... Browse Code »

    """The Marvell® PXA168 processor is the first in a family of application
    processors targeted at mass market opportunities in computing and consumer
    devices. It balances high computing and multimedia performance with low
    power consumption to support extended battery life, and includes a wealth
    of integrated peripherals to reduce overall BOM cost .... """

    See http://www.marvell.com/featured/pxa168.jsp for more information.

    1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core,
    there are many enhancements like instructions for flushing the
    whole D-cache, and so on

    2. Clock reuses Russell's common clkdev, and added the basic support
    for UART1/2.

    3. Devices are a bit different from the 'mach-pxa' way, the platform
    devices are now dynamically allocated only when necessary (i.e.
    when pxa_register_device() is called). Description for each device
    are stored in an array of 'struct pxa_device_desc'. Now that:

    a. this array of device description is marked with __initdata and
    can be freed up system is fully up

    b. which means board code has to add all needed devices early in
    his initializing function

    c. platform specific data can now be marked as __initdata since
    they are allocated and copied by platform_device_add_data()

    4. only the basic UART1/2/3 are added, more devices will come later.
