* arm: mvebu: a38x: serdes specification cleanupKevin Smith2015-11-17-52/+48
| | | | | | | | | | | | Instead of allocating space in the driver for the serdes specification table, just allow the board file to set a pointer to it. Also, allow the board to only specify the lanes that are used instead of including unused lanes.

* arm: mvebu: a38x: Remove unsupported topologiesKevin Smith2015-11-17-1315/+0
| | | | | | | | | | | | | | A lot of extra configuration information was left over in the Marvell serdes and DDR3 initialization code for boards that U-boot does not support. Remove this extra config information, and the concept of fixing up board topologies with information loaded from an EEPROM. If this needs to be done, it should be handled in the board file, not in core code.

| * video: mxsfb: introduce lcdif_power_downPeng Fan2015-11-12-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.

However test result shows that with just VGA Disable bit set and a PCIe graphics card connected to one of the PCIe controllers on the E6xx, accessing the VGA legacy space still causes system hang. After a number of attempts, it turns out besides VGA Disable bit, the SDVO (D3:F0) device should be disabled to make it work. To simplify, use the Function Disable register (offset 0xc4) to disable both IGD (D2:F0) and SDVO (D3:F0) devices. Now these two devices will be completely disabled (invisible in the PCI configuration space) unless a system reset is performed.
