linux-toradex.git/arch/sparc/kernel/leon_pmc.c, branch v3.2.46 Linux kernel for Apalis and Colibri modules SPARC/LEON: power down instruction different of different LEONs 2011-03-17T01:19:04+00:00 Daniel Hellstrom daniel@gaisler.com 2011-01-27T01:26:58+00:00 7279b82cb1975ba4e337a549757f17418cfdffad The way a LEON is powered down is implemented differently depending on CHIP type. The AMBA Plug&Play system ID tells revision of GRLIB and CHIP. This is for example needed by the GR-LEON4-ITX board and the UT699. Previously the power down support for LEON was limited to SMP, now both SMP and UP systems use the instruction.

and CHIP.
