In downstream, this removed region is marked as removed-dma-pool compatible, https://github.com/MiCode/Xiaomi_Kernel_OpenSource/commit/b982b6dc77ac34c184abe83dd293ac08fc607ba3, a carved out memory region not exposed to the kernel. I honestly didn't know what to name this region, so I kept it as it was. I can't boot past the bootloader if I don't mark this region as reserved. > > That said, this overlaps at least &rmtfs_mem, &qseecom_mem and > &camera_mem, so I would expect that you have a few warnings about this > early in the log? Please shuffle things around to avoid this. Sorry, I do know that it definitely overlaps with upstream &rmtfs_mem, but I ignored that because plan was to just boot to shell with this base dts. I was planning to submit a follow-up patch with downstream reserved memory mappings, which do not coincide with the upstream sdm845.dtsi mem regions you mentioned above, along with relevant wifi/adsp/cdsp nodes. But let me take this opportunity to submit them in the next version of this base dts. > > > + no-map; > > + reg = <0 0x88f00000 0 0x1A00000>; > > Please lowercase the 'A' Ack.
