* x86: ns16550: Rework driver to allow for x86 I/O spaceMichel Stam2014-04-093-3/+5
| | | | | | | | | | | | The current implementation fakes a memory-mapped I/O device at 0x3f8 and 0x2f8, then uses platform read/write functions to do the actual reading and writing. These platform functions only exist for the x86 platform; better to move the I/O routines into the driver and have the driver request I/O ports using request_ioport_region.

| | | | | | | | | | The eTSEC 2.0 devices found on the 85xx family of SoCs support stashing buffer descriptors in the L2 cache. This updates the device tree fixup for these devices to ensure that the stashing related properties used by Linux are initialised correctly.

* ppc: add Freescale P1022DS board supportRenaud Barbier2014-03-1915-4/+575
| | | | | | | | | | | | | | | | | | | | | | | Add support for the Freescale P1022DS. Driver support is limited to: - I2C - Ethernet - Serial - NOR flash - PIXIS FPGA System clock configuration is read from the FPGA but has only been tested using a 133MHz system clock and 100MHz DDR clock. Boot arguments are defined in the environment to boot over NFS with a console configured at 115200 bauds. Enabling branch prediction is moved from board support to the platform support for all boards as it is a CPU feature. Some the code is from U-Boot version git-be937b5.

| | | | | | | | | | | | | | | | Add DDR3 support into the MPC8xxx DDR driver. To avoid confusion, the function set_ddr_sdram_mode is renamed set_ddr2_sdram_mode. Checking for errors is simplified in the DDR2 DIMM parameters computation to be consistent with DDR3. This code is derived from the files found in directory drivers/ddr/fsl from U-Boot version git-be937b5.

Moved ffs64 definition to the mpc85xx header files because the function requires the inclusion of linux/log2.h which also includes asm/bitops.h.
