I tested current master successfully on Hummingboard2 with i.MX6 Solo (SOM rev 1.5):
Thanks for testing.
It seems we need more information from Peter about the regression he reported.
It would be helpful if Peter could run a bisect so that we could understand where the regression is coming from.
Finally got the time to test u-boot 2018.09 on my hummingboard 2 and I can also confirm the boot issue with imx6q (Hummingboard 2 MicroSOM i2eX iMX6D - rev 1.3).
The patch set that introduced this regression was part of another pull request, the one that introduces eMMC booting support (from Jon Nettleton, e.g. 86e5a7fc13 and 19ed6063a5). After doing some more testing it seems that the hang happens when trying to verify if the board has eMMC during runtime (has_emmc -> mmc_get_op_cond(mmc)), which is not the case for this SOM in particular (and probably why it works fine on most rev 1.5-based SOMs, as eMMC is usually available there).
Tested with current u-boot master and the issue is still valid.
Jon, did you have any issue when testing that patch set on SOMs without eMMC support?
I tested U-Boot successfully with SOM rev 1.3 (no eMMC) on Hummingboard2, as shown in my previous message on this thread.
Indeed, you tested with i.MX6Q, only difference is that mine is iMX6D, but both without eMMC.
I see the issue with a .IMX6Q wirth SOM rev 1.5 (TI wifi, no EMMC) on a hummingboard2
What toolchain are you using?
Using GCC 8.2 from latest OpenEmbedded. Will try building with the version you used to see if I get any different behavior.
gcc 8.2.x from Fedora 29
What do you see on the serial console?
It boots up to the point when it tries to find the emmc, and then it basically hangs completely (tested with current master):

Exactly the same as I saw.
