common, itest: pass u-boot env variables to itest.s
compare two U-Boot Environment variables with itest.s, example: => print tmp ver tmp=U-Boot 2013.10-g75e ver=U-Boot 2013.10-g75eb4bc (Jan 21 2014 - 10:35:39)MPC83XX => print check_ub_ver check_ub_ver=if itest.s \${tmp} == \${ver}; then echo equal; else echo diff ;fi => run check_ub_ver diff => setenv tmp U-Boot 2013.10-g75eb4bc (Jan 21 2014 - 10:35:39)MPC83XX => print tmp ver tmp=U-Boot 2013.10-g75eb4bc (Jan 21 2014 - 10:35:39)MPC83XX ver=U-Boot 2013.10-g75eb4bc (Jan 21 2014 - 10:35:39)MPC83XX => run check_ub_ver equal Signed-off-by: Heiko Schocher <hs@denx.de>
