region --> variable blocks
partition --> fixed blocks

malloc is implemented as a region

I don't know how much memory you have on your board or what type of
alignment
requirements but I would tend to handle this in the linker script.  If
you
go with malloc you will have to handle the alignment yourself.  If you
go
with partition, you will have to find the memory yourself (malloc or
linker 
script) to only allocate a few blocks.
