b74064a0e2 OMAP3: Avoid re-write to PRM_CLKSRC_CTRL
In function get_osc_clk_speed(), do not change/ update
the divider for SYS_CLK as it can has cascading effect
on the other derived clocks.

Sudden change in divider value can lead to inconsistent
behavior in the system - often leading to crashes.

The problem was found when working with OMAP3EVM using
DM3730 processor card.

The patch has been tested with OMAP3530 on OMAP3EVM as
well

Add a disable sub-command to the cpu command that allows for disabling

33c8c66423 ppc4xx: Allow setting a single SPD EEPROM address for DDR2 DIMMs
On platforms where SPD EEPROM and another EEPROM have adjacent
I2C addresses SPD_EEPROM_ADDRESS should be defined as a single
element array, otherwise DDR2 setup code would fail with the
following error:

ERROR: Unknown DIMM detected in slot 1

However, fixing SPD_EEPROM_ADDRESS would result in another
error:

ERROR: DIMM's DDR1 and DDR2 type can not be mixed.

This happens because initdram() routine does not explicitly
initialize dimm_populated array. This patch fixes the problem.

7693640acd mpc83xx: spd_sdram.c: Disable memory controller before initializing
The memory controller could already be enabled, when spd_sdram() is
called. This could be the case for example, when the SDRAM is initialized
by the JTAG debugger.

The "sync" after the register access via the accessor function is
still needed, because the macro uses the sync before the real write
is done. So until not all accesses are converted to using accessor
functions, this sync still needs to be made "manually" here.
