c60dc8527d mpc512x: Fix problem with I2C access before relocation
This is needed for the upcoming esd MECP5123 board port which uses
I2C EEPROM for environment storage.

3b74e7ec58 MPC512x: remove include/mpc512x.h
Move needed definitions (register descriptions etc.) from
include/mpc512x.h  into  include/asm-ppc/immap_512x.h.

Instead of using a #define'd register offset, use a function that
provides the PATA controller's base address.

All the rest of include/mpc512x.h are register offset definitions
which can be eliminated by proper use of C structures.

There are only a few register offsets remaining that are needed in
cpu/mpc512x/start.S; for these we provide cpu/mpc512x/asm-offsets.h
which is intended as a temporary workaround only. In a later patch
this file will be removed, too, and then auto-generated from the
respective C structs.

843efb1192 MPC512x: use I/O accessors instead of pointer accesses
This commit changes the MPC512x code to use I/O accessor calls (i.e.
out_*() and in_*()) instead of using deprecated pointer accesses.

655b34a78a i2c: Create common default i2c_[set|get]_bus_speed() functions
New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.

Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE.  This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.

ecf5f077c8 i2c: merge all i2c_reg_read() and i2c_reg_write() into inline functions
All implementations of the functions i2c_reg_read() and
i2c_reg_write() are identical. We can save space and simplify the
code by converting these functions into inlines and putting them in
i2c.h.
