Build mfgtool firmware uboot

Hi community,

I'm working on the i.MX6 sabresd Quad platform with no PMIC.

While I try to burn image with mfgtool and I received log that show no pmic detected.

So I assumed that I need to build new uboot and kernel for mfgtool.

I had set the environment for Yocto project and try to build uboot image and kernel image with "bitbake linux-imx-mfgtool" and "bitbake u-boot-mfgtool" .

But I do not know where can I modify uboot code to avoid detecting pmic.

Question:

Is there any document show how to build customize uboot and kernel for mkfgtool firmware?
Is u-boot folder shared with both mfgtool firmware and image of my board?

Using Yocto Project and bibake mfgtool-linux-imx for kernel firmware and bitbake u-boot-mfgtool for uboot firmware.

Does this provide me a single image wich include uboot, kernel and fs in a xxx.imx format that i could download it direktly via the imx_usb_loader?

I'm not really sure that it could do that.

But what I mentioned just can build kernel driver image and uboot image separately.
