Re: [U-Boot] SPL (Secondary Program Loader) on iMX6SL

It was posted a few days ago and the general agreement is that spl should be used instead. For spl example on mx6, you can look at gw_ventana, cm_fx6 and novena boards as references.

Hi Fabio, Thanks for the info. I will try to send some patch or file for iMX6 SabreSD and for iMX6SL-evk later today.

I will start working on spl for mx6 and your patch would be very helpful. Then, I ported it again on iMX6SL-evk, unfortunately, I did not get any data on my serial port window. I played with some different values for CCM_CCGR0 - CCM_CCGR6 and still not getting data. I am not sure exactly what are the big difference between the ROM code of the two chips and why it didn't work. Does anyone could tell me what may be the possible problem?. Please post a patch adding spl support for mx6sl evk (marked as RFC), so that we can try to spot some potential issues. Please add on Cc some of the folks that have previously worked with mx6 spl, so that they could help reviewing it.
