This patch adds support for the MPC8247 based board mgcoge3ne.
Additionaly mgcoge2ne board supprot was removed, because due
to the mgcoge3ne, this board is obsolete and not longer
maintained.
The board is similar to mgcoge. The difference is that
a NUMONYX flash is used and a different SDRAM (256MB).
Also introduce CONFIG_KM_82XX to collect ppc82xx common
settings and remove staticness from the common set_pin function.

Introduce a struct for the BFTICU FPGA to increase the readability of
the code. And the define CONFIG_SYS_BFTICU_BASE was removed because
the CONFIG_SYS_FPGA_BASE is already the base value for BFTICU registers.

The hdlc implementation for mgcoge was initially developed,
but later on not used. Remove the C files, the references
in mgcoge.c and the Makefile to decrease maintenance effort.

This patch adds last_stage_init to all keymile boards. And
in the last stage init some environment variables for u-boot

Normaly the PIGGY_MAC_ADRESS can be read directly from the
IVM on keymile boards. On mgcoge3 it differs. Because there
are two piggy boards deployed the second MAC adress must be
calculated with the IVM mac adress and an offset. This patch
allows to set such a offset in the board config.

This patch fix the i2c deblocking facility with the i2c HW-Controller.
The required delays for byte reading, the enhanced criteria for stop
the dummy read and required 5 start/stop sequences are added.
Add i2c deblocking before ivm eeprom read.
Improve i2c deblocking sequence by respecting stop hold time.
Cleaned function for deblocking. Have now one function i2c_make_abort()
available for bitbang, mpc82xx and mpc83xx harware controller.

For the kmsupx5 a new header file was introduced km8321-common.h.
Now the common stuff from tuxa1, tuda1 and suvd3 was removed and
the new header file included.
The defines CONFIG_SYS_PIGGY_BASE and CONFIG_SYS_PIGGY_SIZE are
confusing. Because they actually describe the KMBEC FPGA values.
The KMBEC FPGA can be PRIO on kmeter1 or upio on mgcoge. Therefore
all the defines were renamed.
remove unneeded variable CONFIG_KM_DEF_NETDEV, as it is
already declared in keymile-common.h

The mgcoge2 board from keymile deploys two different processors.
An ARM based Kirkwood for the "unit" part of the SW and a PPC for
the "ne" part of the SW. Therefore in Linux and U-Boot the names
for the board are mgcoge2un and mgcoge2ne. This patch adds the
mgcoge2ne part of the board. The ppc part of mgboge2 is quite
similar to mgcoge, therefore a generic header km82xx-common.h
was introduced to collect all similiarities. Currently the only
difference is that mgcoge2ne has a 64 MB numonyx NOR flash with
a single die. The mgcoge has a dual die flash 2*32MB from spansion.

- 64MB Flash
- 128 MB DDR2 RAM

This board is similiar to the kmeter1 (8360) board,
so common config options are extracted into the

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

Add support for the ARM part of the mgcoge2, named suen3.
This board is based on the Marvell Kirkwood (88F6281) SoC.
As there come more board variants, common config options
are collected in include/configs/km_arm.h. Also, this board
use common code for all keymile boards, which is stored in
board/keymile/common/common.c

This patch adds the possibility to call a board specific
i2c bus reset routine for the fsl_i2c bus driver, and adds
this option for the keymile kmeter1 board.
The deblock sequence for this board is implemented and
tested in the following way:
CR = 0x20 (release SDA and SCL pin)
CR = 0xa0 (start read)
dummy read
dummy read
if 2. dummy read == 0x00
3. dummy read
CR = 0x80 (SDA and SCL now 1 SR = 0x86)
CR = 0x00 (Modul reset SR=0x81)
CR = 0x80 (SDA and SCL = 1, SR = 0x81)

- CONFIG_SYS_MAX_I2C_BUS changed to 1
We use only one I2C hardwarecontroller on this boards, so
change the CONFIG_SYS_MAX_I2C_BUS to 1.
- common: dont print errormsg if second IVM Block lacks.
- 82xx, mgcoge: fix double mtdpart entry in environment
- 82xx, mgcoge: activate on second Flash the second bank.
- common: CONFIG_ENV_SIZE 0x4000 for all keymile boards
- common: Change malloc size to 1MByte for all Keymile boards
We need a bigger malloc area for the environment support (128k)
on some Keymile boards (kmeter1) and the upcoming UBI support.
Change it to 1MB for all Keymile boards to be on the save side.
Also define CONFIG_SYS_64BIT_VSPRINTF which is needed for
UBI/UBIFS support.
- Add UBI support to all Keymile boards
- change manner of writing "/localbus/ranges" node
instead of writting the complete "/localbus/ranges" node
before booting Linux, only update the ranges entries
which gets dynamical detected (size of flashes).
This is needed, because keymile adds in the DTS
"/localbus/ranges" node entries, which u-boot must
not overwrite/delete.
- kmeter, mgcoge: define 2 seperate regions needed for the Intel P30 chips
The Intel P30 chip has 2 non-identical chips on
one die, so we need to define 2 seperate regions
that are scanned by physmap_of independantly.
- kmeter1: Add MTD concat support to Keymile boards
- 82xx, mgcoge: add "unlock=yes" to default environment
- added CONFIG_MTD_DEVICE to get in sync with mainline code

Many of the help messages were not really helpful; for example, many
commands that take no arguments would not print a correct synopsis
line, but "No additional help available." which is not exactly wrong,
but not helpful either.
Commit ``Make "usage" messages more helpful.'' changed this
partially. But it also became clear that lots of "Usage" and "Help"
messages (fields "usage" and "help" in struct cmd_tbl_s respective)
were actually redundant.
This patch cleans this up - for example:
Before:
=> help dtt
dtt - Digital Thermometer and Thermostat
Usage:
dtt - Read temperature from digital thermometer and thermostat.
After:
=> help dtt
dtt - Read temperature from Digital Thermometer and Thermostat
Usage:
dtt

As documented in doc/I2C_Edge_Conditions, adding a
board specific deblocking mechanism via CFG_I2C_INIT_BOARD
for the mgcoge and mgsuvd board.
This code was originally written by Keymile in association
with Anatech and Atmel in 1998. The Code toggels the SCL
until the SCA line goes to HIGH (max. 16 times).
And after this, a start condition is sent.
This is another approach to deblock the I2C Bus. The
soft I2C driver actually sends 9 clocks with SDA High,
and then a stop at the end, to deblock the I2C Bus.
Maybe we should use the approach from Keymile as
the new standard?
