> Suspend resume for AM33xx as of right now uses this function. This patch [1] uses this function to push the low-level suspend code to sram, it was added here to be consistent with other platforms that utilize the same type of functionality (omap34xx).

Right, but if you look at patch 2/2 in the series, that basically moves all OMAP DT only platforms from using legacy
OMAP private apis to push code/manage sram to using the generic gen_pool apis to manage sram.
Can you look at how you can use gen_pool for am33xx instead of the way omap3 does it, since we want to completely
get rid of the internal sram management apis (or atleast have them only for legacy non-DT OMAP platforms).
