have you seen my SRAM patch series at https://lkml.org/lkml/2012/9/7/281 "Add device tree support for on-chip SRAM" ?
I think the generic SRAM/genalloc driver (https://lkml.org/lkml/2012/9/7/282) could be useful to map the L3RAM on Davinci. With the gen_pool lookup patch (https://lkml.org/lkml/2012/9/7/284) the uio_pruss driver could then use the gen_pool_find_by_phys() (or of_get_named_gen_pool() for initialization from device tree) to retrieve the struct gen_pool*.
This way you could avoid handing it over via platform data and you could get rid of arch/arm/mach-davinci/{sram.c,include/mach/sram.h} completely.
