Víctor committed these patches in 4f24435f [1] for
`linux-omap4_2.6.35.3.bb`. I tried to backport these patches to
`linux-omap-psp_2.6.32.bb` but I am not successful. A lot seems to have
changed between Linux 2.6.32 and 2.6.35.

After the adaptations to `arch/arm/mach-omap2/Makefile` I am now getting
the next error message.

        |   LDS     arch/arm/kernel/vmlinux.lds
        | /tmp/ccpCEAjJ.s: Assembler messages:
        | /tmp/ccpCEAjJ.s:306: Error: selected processor does not support ARM mode `smc #0'
        | /tmp/ccpCEAjJ.s:346: Error: selected processor does not support ARM mode `smc #0'

But I do not know how to adapt that. Is there an easier way to configure
these security extensions?


Thanks,

Paul
