Subject: i.MX31: fix SPI driver for shorter than 32 bit

Fix setting the SPI Control register, 8 and 16-bit transfers
and a wrong pointer in the free routine in the mxc_spi driver.

Subject: 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.

Subject: Add 16bpp BMP support

This patch adds 16bpp BMP support to the common lcd code.

Use CONFIG_BMP_16BPP and set LCD_BPP to LCD_COLOR16 to enable the code.

At the moment it's only been tested on the MIMC200 AVR32 board, but extending
this to other platforms should be a simple task !!

Subject: LCD: support 8bpp BMPs on 16bpp displays

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.

Subject: video: add an i.MX31 framebuffer driver

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.

From a2bb7105a79af8f2ffa9f87256fce6c1cbcbd8e1 Mon Sep 17 00:00:00 2001

Subject: 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.
