bef6d7254e Conditionalize more stuff on TI_AM335X so BEAGLEBONEXM kernel 
builds succeed.

48be462740 am335x: expect the board code to provide a set_mpu_volt() function, 
to change the MPU code voltage. When changing MPU frequency also request
a voltage change. provide frequency/voltage tables for the "blank" revision
and de A revision, based on documents from www.ti.com (this means
it's not possible anymore to request a beaglebone white to run at 1Ghz,
but this was not working anyway).
beagle_machdep.c: callback to the tps65217pmic to change the MPU voltage.

Tested on beaglebone, from 275 to 720Mhz, and on beaglebone black from
300 to 1000Mhz.

111acf9530 Actually, only copy the uboot args if they are within the amount of ram we 
mapped.  If they aren't we'd fault trying to access them.  It's too early
to grab a VA to map them so we just punt for now. XXX

404129e876 more OMAP5 workarounds. 
u-boot doesn't initialize the generic timer on the omap5430 evm properly.
so check to see if it's OK, and if not, initialize omap5 registers properly.
Pass the timer freq via properties to the armgtmr since we can't write the
cnt_frq cp15 register (which can be written in secure mode).

b6c08a30db Set the framebuffer as the default console when no serial port is configured. 
This was tested on a Nokia N900 with the N900 kernel. The BEAGLEBOARD kernel
still builds.
