This is stingray (arch/arm64/boot/dts/broadcom/stingray/bcm958742k.dts).
cma is specified on cmdline as "cma=1G". The full boot log was in the
attachment.
Would you mind attaching it again, I was added to the conversation later.
Sure, it is attached. Thanks for taking a look. This is a boot with
"arch/arm64/configs/defconfig" and the previously mentioned dtb.

Well there's your problem - both zones are only nominally 1GB to begin
with, and both have stuff in them before we even get to placing CMA. To
be honest, even without ZONE_DMA that looks pretty tight.
