The addresses are for the twl4030.
The prescalar that converts the function clock to the sampling
clock is hardcoded to 0. The reference manual recommends 7
if the function clock is 96MHz.
Instead of just changing the hardcoded values, the prescalar
is calculated from the value I2C_IP_CLK.
The i2c #defines are in kHz. The speed passed into the
i2c init routine is in Hz. To be consistent, change the
defines to be in Hz.
The timing calculations are based on what is done in the
linux 2.6.30 kernel in drivers/i2c/buses/i2c_omap.c as
apposed to what is done in TRM.
The major variables in the timing caculations are
specified as #defines that can be overriden as required.
The variables and their defaults are
I2C_IP_CLK SYSTEM_CLOCK_96
I2C_INTERNAL_SAMPLING_CLK 19200000
I2C_FASTSPEED_SCLL_TRIM 6
I2C_FASTSPEED_SCLH_TRIM 6
I2C_HIGHSPEED_PHASE_ONE_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM
I2C_HIGHSPEED_PHASE_ONE_SCLH_TRIM I2C_FASTSPEED_SCLH_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLL_TRIM I2C_FASTSPEED_SCLL_TRIM
I2C_HIGHSPEED_PHASE_TWO_SCLH I2C_FASTSPEED_SCLH_TRIM
This was runtime verified on Zoom1, Zoom2, Beagle and Overo.
The 400kHz and 3.4M cases were verifed on test Zoom1,
Zoom2, Beagle and Overo configurations.
Testing for omap2 will be done in a second step as Nishanth
and Jean-Christophe commented.

Loading vxWorks 5.x images resulted just into 3 or 4 lines of output.
With vxWorks 6.x and the new GCC it emits about 30 lines, which is
far too noisy in my opinion.

Commit 70ebf316 factored out the ROUND() macro into include/common.h,
not realizing that the primary use of this macro on AT91 systems was
in start.S where common.h was not included, and could not be included
because it contains a lot of C code which the assembler doesn't
understand.
This patch wraps such code in common.h in a "#ifndef __ASSEMBLY__"
construct, and then adds an include to cpu/arm926ejs/start.S thus
solving the problem.

Many (especially ARM) tool chains seem to come with broken or
otherwise unusable (for the purposes of builing U-Boot) run-time
support libraries `libgcc.a'. By using the "USE_PRIVATE_LIBGCC"
setting we allow to use alternative libraries instead.
"USE_PRIVATE_LIBGCC" can either be set as an environment variable in
the shell, or as a command line argument when running "make", i. e.
$ make USE_PRIVATE_LIBGCC=yes
or
$ USE_PRIVATE_LIBGCC=yes
$ export USE_PRIVATE_LIBGCC
$ make
The value of "USE_PRIVATE_LIBGCC" is the name of the directory which
contains the alternative run-time support library `libgcc.a'. The
special value "yes" selects the directory $(OBJTREE)/lib_$(ARCH) .
Note that not all architectures provide an alternative `libgcc.a' in
their lib_$(ARCH) directories - so far, only ARM does.

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.

This moves some extern declaration from lcd.c to lcd.h, removing
unneeded ifdef around a pair of them. Additionally, since
gunzip_bmp() was declared static in cmd_bmp.c but extern in lcd.c, I
removed the static. The extra "#include <lcd.h>" in cmd_bmp.c is
added to ensure the header is consistent with the source.
This has been compile-tested on both ARM (at91 boards) and PowerPC
(HH405_config, TQM823L_LCD_config, mcc200_config), to test all use
combinations.

This patch adds a generic command for programming I2C bootstrap
eeproms on PPC4xx. An implementation for Canyonlands board is
included.
The command name is intentionally chosen not to be PPC4xx specific.
This way other CPU's/SoC's can implement a similar command under
the same name, perhaps with a different syntax.
Usage on Canyonlands:
=> chip_config
Available configurations (I2C address 0x52):
600-nor - NOR CPU: 600 PLB: 200 OPB: 100 EBC: 100
600-nand - NAND CPU: 600 PLB: 200 OPB: 100 EBC: 100
