Status of dma-range issues with BCM2711
Hi,
there has been some attempts to fix the booting issues of newer Raspberry Pi 4 (BCM2711 C0) [1] [2]. Since none of them has been applied yet, i wanted to know the status of this?
Best regards

Endless OS chooses this patch series into downstream u-boot. It boots up Endless OS system on RPi 400 correctly.

okay, let me rephrase my question: why haven't any of these patches been applied upstream? E.g. Arch Linux uses upstream U-Boot and periodically gets bug report about this issue.

Dear all,
Last time Peter tested this patch, he raised the issue of also copying the CMA range of set by the firmware, this task being still outstanding today.
I’m happy to resume refining this patch accordingly, unless it could be shipped without the outstanding task.
For reference https://patchwork.ozlabs.org/project/uboot/patch/20220810123927.2567677-2-an...
(Yes this present patch is a resend when it shouldn’t have been and that’s my bad)
Peter, what’s your opinion?
Regards Antoine

I've now become a co-maintainer and this should now be fixed in master for the 2023.04 release soon, let me know if you see any problems.
