build the U-Boot delivered by NXP as a part of their BSP release.

In this case, I suggest you'd rather contact NXP support in order to
address this failure, since it is a vendor BSP you're trying to
upgrade.

In addition, I do not think that all mailing lists you've cross-posted
your question to would be able to help you here:
- linux-mtd list is not really appropriate to solve U-Boot build issues;
- u-boot list is for upstream U-Boot patches and discussions, which is
way past over 2020.04 version (not even considering that you're
building U-Boot from NXP fork);
- oe-core is not a proper list to post questions specific to one SOC vendor;
- meta-freescale 'gatesgarth' branch does not have any U-Boot build
configuration for mx6ull_14x14_evk_nand_config, the only available
build config provided is for sd card;

Having all those points above, I'd suggest you contact NXP support at
first to see if they can solve those build errors for you.

If you would find a solution, you can send a PR to meta-freescale to
address it - this would be much appreciated.
