Attached: 1 video I present the latest in U-Boot Qualcomm development. This is a pre-production Fairphone 5 running U-Boot as a full replacement to Qualcomms proprietary EDK2 stack it has working drivers for the DSI interface, display controller, panel, and a bunch more pesky prerequisites :D This means unlike in the typical case on a phone where the display has already been configured for us by edk2, we have to turn on all the regulators, configure all the clocks and phys, program the display controller and basically do everything ourselves. This is the first command mode panel I have working and being a whole different soc to my initial bringup it proves that the drivers are flexible enough to enable broad support. i hope to eventually land these drivers upstream, starting with the common clock framework port.

Thought about pinging you, but this might make it tough on FP6: https://mastodon.nl/@nicorikken/117202164878007162

I see, but sadly not the same then still using the qualcomm bootloader, but that bootloads U-boot then.

If we could fully replace the qualcomm bootloader we won't get that annoying "the bootloader is unlocked" message on startup.

Running looks like a strong word, based entirely on the thumbnail ;-) I'm not doubting the accuracy of the headline, obviously they're getting this information off the built-in serial port with a VT-100 terminal connected to it.

Halfway through it switches to the phone's own screen, but yeah, looks like it's still receiving commands externally.
