ARM: mxs: fix VDDD brownout setting

At the moment, the desired brownout is at 1.0V. However,
this setting cannot be realized by hardware since we have
only 3 bits to represent the voltage difference from the
target value.

Target value is 1500 mV, brownout target is 1000 mV,
voltage steps are 25 mV.

Register content calculation:
  (1500 [mV] - 1000 [mV]) / 25 [mV] = 20 (decimal) = 0x14

  Register takes only 3 bits, that is 0x4.

But 0x4 * 25 [mV] = 100 [mV], that means that actual
brownout level is 1500 [mV] - 100 [mV] = 1.4 V.

Minimum possible BO level is
  1500 [mV] - 0x7 * 25 [mV] = 1315 [mV].

So lets use this value as desired BO value (which is
also the same as FSL bootlets use).

8 years agodm: timer: Avoid using timer before it is ready

dm: timer: Avoid using timer before it is ready

At present bootstage will try to read the timer very early after relocation.
When driver model is used to provide the timer, we cannot read it until
driver model is ready. Correct this by adding a separate stage for the
post-relocation bootstage init.

This fixes booting on chromebook_link.
