[ELDK] NEW ELDK4.2 for arm warning message?

[udmd-eric wann]

Dear Sir:

        We are trying to use new ELDK tool-chain to compile u-boot.
      Our CPU is arm926ejs based processor.
      To build u-boot is fine, however, we always get the warning message
        "warning: target CPU does not support interworking".
      If we use ourself toolchain, we will not see the warning message.

        We google the warning message, and find
      http://www.nabble.com/-PATCH--Remove-warning:-target-CPU-does-not-support-interworking-in-ARMv6-to9488637.html

      Could we safe ignore the warning message?

      Thanks for any help.

      Best Regards

      Eric Wann
