06bffc6ea5 rm9200 lowevel_init: don't touch reserved/readonly registers
For some reason the AT91rm9200 lowlevel init writes to a bunch of
reserved or read-only addresses.  All the boards seem to define the
value-to-be-written values as zero ... but they shouldn't actually
be writing *anything* there.

No documented erratum justifies these accesses.  It looks like maybe
some pre-release BDI-2000 setup code has been carried along by cargo
cult programming since at least late 2004 (per GIT history).

Here's a patch disabling what seems to be bogosity.  Tested on a
csb337; there were no behavioral changes.

70ebf31633 AT91: factor out ROUND() macro
A large number of boards (all AT91 based) duplicated the ROUND()
macro in their board specific config files. Add the definition to
include/common.h and clean up the board config files.

d48eb5131d i2c: Remove deprecated individual i2c commands
The following individual I2C commands have been removed: imd, imm, inm,
imw, icrc32, iprobe, iloop, isdram.

The functionality of the individual commands is still available via
the 'i2c' command.

This change only has an impact on those boards which did not have
CONFIG_I2C_CMD_TREE defined.
