Modify RCW on LS1021A-iot

I am hoping to find some guidance on how to modify the RCW for my 1021a-iot system.  I want to enable some GPIO for testing purposes.  I just need some help on how to program the value not the values themselves.    I do not have code warrior and hence no QCVS which is the only mention of how to do this I have found.

I am currently using the SD card as boot location if that makes any difference on the procedure.

 

Can I change the defaults inthe u-boot  and have the new RCW automatically built by bitbake.

As simply as ...

bitbake -c cleansstate u-boot-ls1

bitbake -c patch u-boot-ls1

bitbake u-boot-ls1

 

Documents I have found  so far don't seem to address this.  I am pretty new still at yocto and patching etc.. 

 

Thank You
