[U-Boot] Regression: bootz command fails in v2013.07-rc2

[U-Boot] Regression: bootz command fails in v2013.07-rc2

[Tetsuyuki Kobayashi]

Hello,

I found bootz command causes 'undefined instruction' exception
on KZM-A9-GT board (armv7) in v2013.07-rc2.

KZM-A9-GT# tftp zImage.kzm9g.v310; bootz

At v2013.07-rc1, it was good.
I tried 'git bisect' and got this result.

$ git bisect good

    Refactor the bootm command to reduce code duplication
    
Please take a look.

Thanks for letting me know - also there is another thread about this.

I will post some v2 patches soon, perhaps you can try to test and report
back.
