/*
* The "dram_stack" field of the RCP task structure is set to this address.
* It is placed in its own .c, and thus its own .o, since the linker aligns
* individual relocatables to data cache line size (16 byte) boundaries.
*
* This avoids the problem where the dram_stack data is accidentally
* scribbled over during a writeback for data sharing the same line.
