calebccff Tartarus what the driver does is use the lmb api's to get va's in a top-down manner. this can be replaced by a simple logic. for the current logic used in the driver, we don't need to do anything more complicated
<sng>
calebccff we do have the concept of having a different lmb instance for running tests. but i don't want to have other consumers of that logic as far as possible. don't want to set any precedent here. especially given what is expected by the apple iommu driver can be achieved by a very simple static function.

building uboot with clang: should it just work?

It Depends(tm)
<Tartarus>
A regular part of my test cycle, for 32 and 64bit, is Pi with (currently) clang-16
<Tartarus>
But I also regularly don't test say beagleplay because we need some Kbuild changes to be backported so that the r5 side of the world can be built
<Tartarus>
I used to test some other aarch64 platforms and they did work, arm32 is where I had other problems last time I tried
<Tartarus>
That also means, however, setting CROSS_COMPILE and letting that be used to figure out target flags, so I for example do export CROSS_COMPILE=/opt/gcc-13.2.0-nolibc/aarch64-linux/bin/aarch64-linux- then make CC=clang-16 HOSTCC=clang-16 rpi_3_defconfig all
<Tartarus>
Using clang for as/ld/etc is to varying degrees maybe possible? last I tried I believe we missed a few things to have the linker work, at least for also LTO

Sigh... test/cmd/mem.c assumes usable memory starts at zero, so is fine on Pi, blows up on the first platform I try where that's not true (a TI one)
<Tartarus>
I think I can make this work..
