[U-Boot] [PATCH] Add feature-removal-schedule.txt

[Peter Tyser <ptyser@xes-inc.com>]

> +What:	Individual I2C commands
> +When:	April 2009
> +Why:	Per the U-Boot README, individual I2C commands such as "imd", "imm",
> +	"imw", etc are deprecated.  The single "i2c" command which is
> +	currently enabled via CONFIG_I2C_CMD_TREE contains the same
> +	functionality as the individual I2C commands.  The individual

Would people prefer there be a period of time where both the individual
i2c commands as well the single "i2c" command are both supported for
boards without CONFIG_I2C_CMD_TREE?  If so, I'd add some deprecation
messages to the individual commands.

Its a little PITA to add a "DEPRECATED" message to all the "old style"
commands as they are also called by the newer "i2c" command, so just
wanted to check before submitting a patch.

Thanks,
Peter
