allmodconfig is broken by the addition of the -mcpu=cortex-a9
flag for smc.S:
arch/arm/mach-tango/smc.S:1:0: warning: switch -mcpu=cortex-a9 conflicts with -march=armv6k switch

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:
