2010-12-17sh: mach-sdk7786: Handle baseboard NMI source selection.Paul Mundt
The on-board NMI switch is routed through and mangled by the FPGA prior to its delivery to the NMI pin, so add some glue for the various configuration options. The default is to unmask it and enable all input sources. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-15sh: mach-sdk7786: Add support for the FPGA SRAM.Paul Mundt
This ties in the 2KiB of FPGA SRAM in to the generic SRAM pool. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-14sh: pci: Support secondary FPGA-driven PCIe clocks on SDK7786.Paul Mundt
The SDK7786 FPGA has secondary control over the PCIe clocks, specifically relating to the slots and oscillator. This ties the FPGA clocks in to the clock framework and balances the refcounting similar to how the primary on-chip clocks are managed. While the on-chip clocks are per-port, the FPGA clock enable/disable is global for the entire block. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-10-14sh: pci: Support slot 4 routing on SDK7786.Paul Mundt
SDK7786 supports connecting either slot3 or 4 to the same PCIe port by way of FPGA muxing. By default the vertical slot 3 on the baseboard is enabled, so this adds in a command line option for forcibly enabling the slot 4 edge connector. If nothing has been specified on the command line, we fall back to reading the resistor values for card presence to figure out where to route the port to.

2010-04-19sh: mach-sdk7786: pm_power_off support.Paul Mundt
This wires up power-off support for the SDK7786 board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-20sh: mach-sdk7786: Probe system FPGA area mapping.Paul Mundt
This implements dynamic probing for the system FPGA. The system reset controller contains a fixed magic read word in order to identify the FPGA. This just utilizes a simple loop that scans across all of the fixed physical areas (area 0 through area 6) to locate the FPGA. The FPGA also contains register information detailing the area mappings and chip select settings for all of the other blocks, so this needs to be done before we can set up anything else.

2010-01-20sh: mach-sdk7786: Split out FPGA IRQ controller setup.Paul Mundt
This moves out the FPGA IRQ controller setup code to its own file, in preparation for switching off of IRL mode and having it provide its own irq_chip. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-01-20sh: mach-sdk7786: FPGA updates.Paul Mundt
This does a bit of refactoring of the FPGA management code. The primary FPGA initialization is moved out to its own file in preparation for implementing some of the more complex capabilities, a complete set of register definitions is provided, and all of the existing users in the board code are moved over to use the new interface instead of setting up overlapping mappings. This also corrects the FPGA size, which previously was chomped off at the SDIF control register. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
