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.

regards
Philipp
