HI, I think on the imx8mq platform we have a problem with the introduction of the clock driver. I tried to debug the problem that the pitx-imx8m board was not able to start for some time. I was wondering why the pitx-im8m doesn't work anymore although the imx8mq_evk is running. So I switched to the imx8mq_evk for counter testing. As I already figured out in [1] also the imx8mq_evk is not able to start properly. On the EVK I enabled the DEBUG_UART and see the outputs below. I suspect all imx8mq boards have this problem.

Seems SPL_DM_CLK consumes the malloc space, so you meet such error. Regards Peng
