/* DSP RAM regions (all of them) are mapped twice on the DSP: once in
* a 512MB region from 0x80000000-0x9fffffff and again from
* 0xa0000000-0xbfffffff. The first mapping is set up to bypass the
* L1 cache, so it must be used when multiprocessor coherence is
* desired, where the latter mapping is best used for processor-local
* data (e.g. stacks) or shared data that is managed with explicit
* cache flush/invalidate operations.
*
* These macros will set up a segment start address correctly,
* including alignment to a cache line. Be sure to also emit the
* section to ">ram :ram_phdr" or ">ucram :ucram_phdr" as
* appropriate. (Forgetting the correct PHDR will actually work, as
* the output tooling ignores it, but it will cause the linker to emit
* 512MB of unused data into the output file!)
*
* (Note clumsy syntax because XCC doesn't understand the "~" operator)
