2016-02-24arm: am437x: cm-t43: set MPU and CORE voltages on bootNikita Kiryanov
During boot, U-Boot raises the CPU frequency but the CORE and MPU regulators are not updated. This is not a problem in cold boot since the default values that the pmic outputs are correct, but if Linux were to switch the module to a low power OPP, the new voltage values will be retained after a reboot and the module will likely hang once U-Boot raises the CPU frequency back up. Set both CORE and MPU regulators to to 1.1V on boot.

2016-02-24arm: am437x: cm-t43: get rid of enable_vtt_regulator()Nikita Kiryanov
CM-T43 does not have a vtt regulator. Remove the function that's supposed to enable it.

2016-02-24arm: am437x: cm-t43: set tps fseal bitNikita Kiryanov
Set TPS65218 FSEAL bit to 1 so that RTC could be powered using on-board 3V battery. This is necessary so that time and date will survive reboots and power offs.

2016-02-24arm: am437x: cm-t43: split board fileNikita Kiryanov
Simplify the board file by splitting it to spl portion and u-boot portion. Some unnecessary includes were identified and removed. No functional changes.
