BoardId and HWKey are used to identify the HW class of a given board.
The correct values are stored in the inventory eeprom. During creation
time of a boot package the boardId and HWkey for the SW is stored in
the default environment and burned into the flash. During boottime
the values in the inventory and in the environment are compared to
avoid starting of a SW which is not authorized for this board.
Some bootpackages are allowed to run on a set of different boardId
hwKey. In this case the environment variable boardIdListHex was added
to the default environment. In this case the command iterates over the
pair values and compares them with the values read from the inventory
eeprom.
The syntax of such a boardIdListHex value is e.g.: 158_1 159_1 159_2

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.

- 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.

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?
