      [ARM] pxa: add base support for Marvell's PXA168 processor line · 49cbe786
      Eric Miao authored
      """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 .... """

       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.
