I thought there were people who were using video in U-Boot, but maybe I am wrong.
There are no video drivers for MX8M in U-Boot, it's all USB and maybe sometimes in the future PCIe.
Oh good.
I'll try to test it on an imx8mq when I get some time.
The entire stack of patches is at:
https://source.denx.de/u-boot/custodians/u-boot-usb/-/commits/imx-8mp
For the series:
Tested-By: Tim Harvey tharvey@gateworks.com #imx8mp-venice-defconfig
This was tested on an IMX8MP board that I'm bringing up (imx8mp-venice-defconfig) but have not yet submitted.
Nice. If you want to add TB for any other patches you tested, that would be welcome. I think there are a few more involved.
I tried to build the imx8mq last night, but I ran into issues. I never built an imx8mq bootloader before, so I think I'm missing something. I'll try to get to it again this week. Sorry for the delays.
