* avr32: Add gclk helper functionsHaavard Skinnemoen2008-09-01-0/+25
| | | | | | | | | | | Add two helper functions for configuring and enabling generic clocks: - gclk_enable_output: Enables output on a GCLKx pin - gclk_set_rate: Configures a gclk to run at a specific rate This should eliminate any reason to go mucking about with PM registers from board code.

* avr32: refactor the portmux/gpio codeHaavard Skinnemoen2008-09-01-317/+298
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Separate the portmux configuration functionality from the GPIO pin control API. - Separate the controller-specific code from the chip-specific code. - Allow "ganged" port configuration (multiple pins at once). - Add more flexibility to the "canned" peripheral select functions: - Allow using more than 23 address bits, more chip selects, as well as NAND- and CF-specific pins. - Make the MACB SPEED pin optional, and choose between MII/RMII using a parameter instead of an #ifdef. - Make it possible to use other MMC slots than slot 0, and support different MMC/SDCard data bus widths. - Use more reasonable pull-up defaults; floating pins may consume a lot of power. - Get rid of some custom portmux code from the mimc200 board code. The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.

| * USB: Add support for OHCI controller on S3C6400Guennadi Liakhovetski2008-08-31-0/+46
| | | | | | | | | | | | | | | | Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could try to enable the MMU, but map addresses 1-to-1, and disable data cache, then it should work too and we could still profit from instruction cache.

| * ARM DaVinci: Changing function names for EMAC driverSandeep Paulraj2008-08-31-79/+79
| | | | | | | | | | | | | | | | | | | | DM644x is just one of a series of DaVinci chips that use the EMAC driver. By replacing all the function names that start with dm644x_* to davinci_* we make these function more portable. I have tested this change on my EVM. DM6467 is another DaVinci SOC which uses the EMAC driver and i will be sending patches that add DaVinci DM6467 support to the list soon. Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>

* FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala2008-08-27-2/+2432
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.

It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.
