Re: [U-Boot] [U-Boot, 09/10] arm: am437x: cm-t43: set MPU and CORE voltages on boot

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.

Applied to u-boot/master, thanks!
