    ARM: SPEAr3xx: Add device-tree support to SPEAr3xx architecture · c5fa4fdc
    Viresh Kumar authored
    This patch adds a generic target for SPEAr3xx machines that can be configured
    via the device-tree. Currently the following devices are supported via the
    devicetree:
    
    - VIC interrupts
    - PL011 UART
    - PL061 GPIO
    - PL110 CLCD
    - SP805 WDT
    - Synopsys DW I2C
    - Synopsys DW ethernet
    - ST FSMC-NAND
    - ST SPEAR-SMI
    - ST SPEAR-KEYBOARD
    - ST SPEAR-RTC
    - ARASAN SDHCI-SPEAR
    - SPEAR-EHCI
    - SPEAR-OHCI
    
    Other peripheral devices will follow in later patches.
    
    This also removes IO_ADDRESS macro and creates 16 MB static mappings instead of
    4K for individual peripherals. This is done to have efficient TLB lookup for any
    I/O windows that are located closely together. ioremap() on this range will
    return this mapping only instead of creating another.
