/* Stack for the OS image.  Default in ldscript.common is 8488, but the AT91 only
 * has 64K of SRAM and the stack is carved out of the same pool as BigBuf:
 *   BigBuf = _stack_start - __bss_end__,  _stack_start = sram_end - stacksize - commonarea
 * so every byte here is a byte BigBuf does not get.  Worst-case stack measured
 * across all 41 standalone modes (-fstack-usage + call graph, VLA bounds added
 * in) is 5408 bytes, so 7168 keeps ~1.7 kB of headroom and hands 1320 bytes back
 * to BigBuf.  Re-measure before lowering this further - overflow grows silently
 * down into the top of BigBuf, where BigBuf_malloc() hands out chunks.
 * Not set for AT32/PM5, which has 512K of SRAM and no such pressure.
