According with this discussion [1] the new assemblers need -march=armv7-a+sec on command line or .arch_extension sec inline to enable use of the smc instruction.
In the sakoman's u-boot repository there is branch for the omap4 [2] which uses the smc instruction with the -march=armv7-a, and it will not compile with the latest binutils (2.21)
Just to clarify -- my branch has Aneesh's "armv7: adapt omap4 to the new cache maintenance framework" patch series in it.
So this issue will arise only when Aneesh's patch series is applied.
I have a bsic question: do we really need -march=armv7-a at all in U-Boot? What is it good for?
Best regards,
Wolfgang Denk
