09d318a8bb fsl_i2c: Use timebase timer functions instead of get_timer()
The current implementation of get_timer() is only really useful after we
have relocated u-boot to memory.  The i2c code is used before that as part
of the SPD DDR setup.

We actually have a bug when using the get_timer() code before relocation
because the .bss hasn't been setup and thus we could be reading/writing
a random location (probably in flash).

e4dafff86f fsl-i2c: fix writes to data segment before relocation
Prevent i2c_init() in fsl_i2c.c from writing to the data segment before
relocation.  Commit d8c82db4 added the ability for i2c_init() to program the
I2C bus speed and save the value in i2c_bus_speed[], which is a global
variable.  It is an error to write to the data segment before relocation,
which is what i2c_init() does when it stores the bus speed in i2c_bus_speed[].

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

d8c82db482 Add support for setting the I2C bus speed in fsl_i2c.c
Add support to the Freescale I2C driver (fsl_i2c.c) for setting and querying
the I2C bus speed.  Current 8[356]xx boards define the CFG_I2C_SPEED macro,
but fsl_i2c.c ignores it and uses conservative value when programming the
I2C bus speed.
