I want to run Linux v5.15 on iMX6UL(iW-RainboW-G18D) by 5.15-honister

I decided that there was no suitable one for MACHINE, so I chose "imx6ulevk".
The reason is that v4.1.15 BSP had imx6-iwg18.conf, but it does not exist in 5.15-honister.

Also, I wanted to specify "nand" for UBOOT_CONFIG, but there is no definition in imx6ulevk.conf, so I chose "emmc".

I was able to create the following files. But when I tried to flush u-bbot with uuu it got stuck.
-> u-boot-emmc-2021.04-r0.imx

Looking at the output of 512MB in the DRAM item, it seems that the difference in specifications from the i.MX6UltraLite Evaluation Kit is having an effect.

Please help me get Linux v5.15 running successfully.
If it's impossible, say it's impossible.

Best regard.
