Subject: [U-Boot] [PATCH 8/9] video: add a i.MX31 framebuffer driver
	only for bitmaps so far
To: [email-masked]
Cc: [email-masked]
Message-ID: <[email-masked]>
Content-Type: TEXT/PLAIN; charset=US-ASCII

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: Guennadi Liakhovetski <[email-masked]>
Subject: [U-Boot] [PATCH 9/9] ARM: add an "eet" variant of the
	imx31_phycore	board
To: [email-masked]
Cc: [email-masked]
Message-ID: <[email-masked]>
Content-Type: TEXT/PLAIN; charset=US-ASCII

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.
