[yocto] Is it necessary to specify TARGET_ARM = "arm" ?

[Elvis Dowson]

Hi,
      If in my overo.inc file, I specify the following:

SOC_FAMILY = "omap3"
require conf/machine/include/soc-family.inc

require conf/machine/include/omap3.inc
require conf/machine/include/tune-cortexa8.inc

Is it necessary to specify TARGET_ARCH = "arm"  for the machine configuration?

The machine configurations in the meta-ti repositories don't have them any more.

Best regards,

Elvis Dowson
