dbe6f1eb93 rpi: get rid of BCM2835_BOARD_REV_* macros
There are two numbering schemes for the RPi revision values; old and new
scheme. The values within each scheme overlap. Hence, it doesn't make
sense to have absolute/global names for the revision IDs. Get rid of the
names and just use the raw revision/type values to set up the array of
per-revision data.

This change makes most sense when coupled with the next change. However,
it's split out so that the mechanical cut/paste is separate from the
logic changes for easier review and problem bisection.

85cf0e6299 arm: dts: omap: add reg-shift to serial device tree node
With the commit 'c7b9686d5d48 ("ns16550: unify serial_omap")' all
TI platforms are broken with DM/DT boot as ns16550 driver expects
reg-shift from DT which is not populated for TI platforms.
Earlier it worked as it was hard coded to 2 in serial-omap
driver. So adding the reg-shift to serial nodes for dra7, am4372
and am33xx dtsi files. Tested this patch on am437x-sk-evm,
am437x-gp-evm, am335x-boneblack, dra74x-evm and dra72x-evm.

cd3187d6b2 rockchip: move SYS_MALLOC_SIMPLE to mach-rockchip Kconfig
Commit 1eb0c03c21 added
SPL_SYS_MALLOC_SIMPLE Kconfig option and changed the way it is
evaluated.

Thus, the definitions of CONFIG_SYS_MALLOC_SIMPLE in rk3***_common.h
board configs are now incorrect because CONFIG_SPL_BUILD is enabled so
CONFIG_IS_ENABLED(SYS_MALLOC_SIMPLE) will look for SPL_SYS_MALLOC_SIMPLE
instead of SYS_MALLOC_SIMPLE.

This commit fix this enabling SPL_SYS_MALLOC_SIMPLE with the new Kconfig
option by default in rockchip-mach.

a6b1e25fc6 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).
