[ARM] 3960/1: AT91: Final SAM9 intergration patches.
This patch includes a number of small changes for integrating the AT91SAM9261 and AT91SAM0260 support. * Can only select support for one AT91 processor at a time. * Remove most of the remaining static memory mapping for the AT91RM9200. * Reserve 1Mb of memory below the IO for mapping the internal SRAM and any custom board-specific devices (ie, FPGA). * The SAM9260 has more serial ports, so increase the maximum to 7. * Define the standard chipselect addresses, and define other addresses relative to those. * CLOCK_TICK_RATE is different on the SAM926x's.
