ARM: tango4: Initial platform support Support Sigma Designs ARM-based (specifically, Cortex-A9 MPCore r3p0) Tango4 "Secure Media Processor" platforms: smp8756, smp8758, smp8759 (8756 is single-core, the latter are dual-core). Note: 8758 vs 8759: same chip, different package. Support for older MIPS-based platforms can be found elsewhere: https://github.com/mansr/linux-tangox Signed-off-by: Marc Gonzalez <marc_gonzalez@sigmadesigns.com> Reviewed-by: Kevin Hilman <khilman@linaro.org> Signed-off-by: Olof Johansson <olof@lixom.net> 2015-12-15 09:41:13 +00:00			`extern int tango_smc(unsigned int val, unsigned int service);`
