6a372e940d arm920t/at91: use new clock.c features
This patch enables the new clock features from arm920t/at91/clock.c. This
is an required step to get at91rm9200_usart replaced by atmel_usart driver.

a429db7e3c arm920t/at91/timer: replace bss variables by gd
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc
bss values in arm920t/at91/timer driver.
The usage of bss values in driver before initialisation of bss is
forbidden. In that special case some data in .rel.dyn gets corrupted by
the arm920t/at91/timer driver.

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

99fa97e955 at91rm9200ek: convert to at91
This patch removes some functionality from at91rm9200ek board but the
remaining functionality does now work with newer at91 code and
arm-relocation.

Currently missing features are:
 - dataflash booting (due to missing HW for testing)
 - MMC/SD-Card
 - first stage bootloader support is completely removed (not needed for
   NOR)

Cause this board was (some days ago) reference for all at91rm9200 based
boards this should be a good starting point to convert all remaining
at91rm9200 borads to at91 code. Aside from that this is a good base to
get some drivers between at91sam/at91rm/avr32 merged.

425de62d40 add new CONFIG_AT91_LEGACY
* add's the new temporary CONFIG_AT91_LEGACY to all board configs
 This will need for backward compatiblity, while change the SoC access
 to c structures. If CONFIG_AT91_LEGACY is defined, the deprecated
 SoC is used.

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.

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.
