I have an off-topic question though: have you ever managed to boot mx7solo with a mainline kernel?
Yes, it works nicely, just make sure you disable the second USB port:
&usbotg2 { status = "disabled"; };
&usbmisc2 { status = "disabled"; };
&usbphynop2 { status = "disabled"; };
Did as suggested, but it did not help booting warp7 with mainline.
Also applied your "clk: imx: do not sleep if IRQ's are still disabled" patch and this is what I get:

Do you select "CONFIG_ARMV7_PSCI_NR_CPUS 2" from include/configs/mx7_common.h in your mx7s board? Any ideas?
Thanks
