Platform: AM335x without PMIC
File: arch/arm/mach-omap2/pm33xx.c & sram.c
SuspendToRam has to be enabled for completing all the compilation.
It seems the code does not handle CONFIG_CPU_PM or CONFIG_SUSPEND well in function am33xx_pm_init & am33xx_sram_init.
Actually, I have used SDK7 to the latest 01_00_00_00.
Since there is no PMIC on the target board, the voltage control to PMIC is not required anymore.
I think TI engineers do not consider this kind of application.
The error message should be similar to:

Hi,
As you've noticed those errors appear, because most of the functions in pm33xx.c driver are implemented under the #ifdef CONFIG_SUSPEND & #ifdef CONFIG_CPU_PM conditions & when you disable these two in your defconfig the build will fail.
If you need to disable susped & runtime PM, the correct approach is to use menuconfig and deselect the highlighted options bellow:
Power Management Options
--> [*] Suspend to RAM and standby //deselect these by pressing 'n'
--> -*- Run-time PM core functionality
Best Regards,
Yordan
hmm... I got warnings during initiation. (no power management by deselecting PM_RUNTIME)
