The difference between this platform and the already existing P2020RDB is mainly with respect to DDR. The P2020RDB-PC has a DDR3 memory. The P2020RDB-PC also has a CPLD device connected to local bus. The main differences from the P102x RDB-PC is 64-bit DDR and SYSCLK of 100Mhz.

Back in the FSL bsp it was set to 50Mhz and working. However the driver divided the SoC freq. only by 2. According to the TRM the platform clock (which the manual refers in its formula) is the system clock divided by two. So in the end it has to divide by 4 and this is what the fsl-spi driver in tree is doing. Since then the flash is not wokring I guess. After chaning the freq from 50Mhz to 40Mhz like others do then I can access the flash.

When the DIU is enabled, the bulk of the local bus is disabled, preventing access to memory-mapped devices like NOR flash and the pixis FPGA. Therefore, if the DIU is going to be enabled, then memory-mapped devices on the localbus, like NOR flash, need to be disabled. This also means that the localbus is not a 'simple-bus' any more, so remove that string from the compatible node.

Switching between the DVI and LVDS monitor ports is handled by the pixis, so that switching needs to be done via indirect mode. This has the side-effect of no longer requiring U-Boot to enable the DIU. Now Linux can enable the DIU all by itself.

The bootloader sets the PCI bridge to open a window from 0x0000 to 0x1fff on the PCI I/O space. But the kernel can't set the I/O resource. In the routine pci_read_bridge_io(), if the base which is read from PCI_IO_BASE is equal to zero, the routine don't set the I/O resource of the child bus. To allow the legacy I/O space on the VIA southbridge to be accessed, use the fixup to fix the PCI I/O space of the PCI bridge.
