Generic udelay() with watchdog support

2009-12-05T00:08:53+00:00

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.

This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

Add AVR32 LCD support

2009-07-26T11:12:02+00:00

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: Make cacheflush cpu-dependent

2009-02-23T09:34:23+00:00

The AT32UC3A series of processors doesn't contain any cache, and issuing
cache control instructions on those will cause an exception. This commit
makes cacheflush.h arch-dependent in preparation for the AT32UC3A-support.

avr32: Add support for "GPIO" port mux

2008-09-01T12:38:46+00:00

The "GPIO" port mux is used on AVR32 UC3 parts as well as AT32AP7200 and
all later AVR32 chips. This patch adds a driver for it, implementing the
same API as the existing portmux-pio driver but with more functionality.

avr32: Use board_postclk_init instead of gclk_init

2008-09-01T12:21:34+00:00

Replace the avr32-specific gclk_init() board hook with the standard
board_postclk_init() hook which is supposed to run at the same point
during initialization.

Provide a dummy weak alias for boards not implementing this hook. The
cost of this is:
  - 2 bytes for the dummy function (retal 0)
  - 2 bytes for each unnecessary function call (short rcall)

which is a pretty small price to pay for avoiding lots of #ifdef
clutter. In this particular case, all boards probably end up slightly
smaller because we avoid the conditional checking if the gclk_init
symbol is NULL.

avr32: Add gclk helper functions

2008-09-01T12:21:34+00:00

Add two helper functions for configuring and enabling generic clocks:
  - gclk_enable_output: Enables output on a GCLKx pin
  - gclk_set_rate: Configures a gclk to run at a specific rate

This should eliminate any reason to go mucking about with PM registers
from board code.

avr32: refactor the portmux/gpio code

2008-09-01T12:20:41+00:00

  - 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.
