* Add AVR32 LCD supportMark Jackson2009-07-26-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the AVR32 LCD controller. This patch is based off the latest u-boot-video. A quick summary of what's going on:- Enable LCDC pixel clock Enable LCDC port pins Add framebuffer pointer to global_data struct Allocate framebuffer To use the new code, update your board config to include something like this:- #define CONFIG_LCD 1 #if defined(CONFIG_LCD) #define CONFIG_CMD_BMP #define CONFIG_ATMEL_LCD 1 #define LCD_BPP LCD_COLOR16 #define CONFIG_BMP_16BPP 1 #define CONFIG_FB_ADDR 0x10600000 #define CONFIG_WHITE_ON_BLACK 1 #define CONFIG_VIDEO_BMP_GZIP 1 #define CONFIG_SYS_VIDEO_LOGO_MAX_SIZE 262144 #define CONFIG_ATMEL_LCD_BGR555 1 #define CONFIG_SYS_CONSOLE_IS_IN_ENV 1 #define CONFIG_SPLASH_SCREEN 1 #endif The standard U-Boot BMP and Splash-screen features should just work.

* avr32: refactor the portmux/gpio codeHaavard Skinnemoen2008-09-01-0/+89
- Separate the portmux configuration functionality from the GPIO pin control API. - Separate the controller-specific code from the chip-specific code. - Allow "ganged" port configuration (multiple pins at once). - Add more flexibility to the "canned" peripheral select functions: - Allow using more than 23 address bits, more chip selects, as well as NAND- and CF-specific pins. - Make the MACB SPEED pin optional, and choose between MII/RMII using a parameter instead of an #ifdef. - Make it possible to use other MMC slots than slot 0, and support different MMC/SDCard data bus widths. - Use more reasonable pull-up defaults; floating pins may consume a lot of power. - Get rid of some custom portmux code from the mimc200 board code. The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.
