Software Configuration:
=======================
to run and CONFIG_SYS_I2C_SLAVE to be the address of this node (ie
the CPU's i2c node address).
- Now, the u-boot i2c code for the mpc8xx (cpu/mpc8xx/i2c.c)
- sets the CPU up as a master node and so its address should
- therefore be cleared to 0 (See, eg, MPC823e User's Manual
- p.16-473). So, set CONFIG_SYS_I2C_SLAVE to 0.

CONFIG_SYS_I2C_INIT_MPC5XXX
custom i2c_init_board() routine in boards/xxx/board.c
is run early in the boot sequence.
+ CONFIG_SYS_I2C_BOARD_LATE_INIT
+
+ An alternative to CONFIG_SYS_I2C_INIT_BOARD. If this option is
+ defined a custom i2c_board_late_init() routine in
+ boards/xxx/board.c is run AFTER the operations in i2c_init()
+ is completed. This callpoint can be used to unreset i2c bus
+ using CPU i2c controller register accesses for CPUs whose i2c
+ controller provide such a method. It is called at the end of
+ i2c_init() to allow i2c_init operations to setup the i2c bus
+ controller on the CPU (e.g. setting bus speed & slave address).
+
CONFIG_I2CFAST (PPC405GP|PPC405EP only)
This option enables configuration of bi_iic_fast[] flags

- CONFIG_PCI_DISABLE_PCIE:
Disable PCI-Express on systems where it is supported but not
(no, we don't intend to provide a full virtual machine interface to
Linux :-).
-But now you can ignore ALL boot loader code (in arch/ppc/mbxboot).
