ARM: add an "eet" variant of the imx31_phycore board
The "eet" variant of the imx31_phycore board has an OLED display, using a
s6e63d6 display controller on the first SPI interface, using GPIO57 as a
chip-select for it. With this configuration you can display 256 colour BMP
images in 16-bit RGB (RGB565) LCD mode.
Add a driver for the Synchronous Display Controller and the Display
Interface on i.MX31, using IPU for DMA channel setup. So far only
displaying of bitmaps is supported, no text output.
This patch also simplifies some ifdefs in lcd.c, introduces a generic
vidinfo_t, which new drivers are encouraged to use and old drivers to switch
over to.
A driver for the S6E63D6 SPI display controller from Samsung
This is a driver for the S6E63D6 SPI OLED display controller from Samsung.
It only provides access to controller's registers so the client can freely
configure it.
i.MX31: support GPIO as a chip-select in the mxc_spi driver
Some SPI devices have special requirements on chip-select handling.
With this patch we can use a GPIO as a chip-select and strictly follow
the SPI_XFER_BEGIN and SPI_XFER_END flags.
This patch fixes an issue in config space read accessors: we should
fill-in the value even if we fail (e.g. skipping devices), otherwise
CONFIG_PCI_SCAN_SHOW reports bogus values during boot up.

mpc83xx: PCIe: Don't start bus enumeration at 0
Currently we assign first_busno = 0 for the first PCIe hose, but this
scheme won't work if we have ordinary PCI hose already registered (its
first_busno value is 0 too).
The old code worked fine only because we have PCI disabled on
MPC837XEMDS boards in stand-alone mode (see commit 00f7bbae92e3b13f2b3
"mpc83xx: fix PCI scan hang on the standalone MPC837xE-MDS boards").
But on MPC837XERDB boards we have PCI and PCIe, so the bug actually
triggers.
So, to fix the issue, we should use pci_last_busno() + 1 for the
first_busno (i.e. last available busno).
