[U-Boot] [arm] Where to put files for armv8 ThunderX
I have just been handed the task of cleaning up our U-Boot port to our ThunderX armv8 chip and am wondering where I should put the files specific to our chip.
The people who previously worked on the chip created a subdirectory under u-boot and have things scattered about.
Should I create a subdirectory under arch/arm/cpu/armv8 like arch/arm/cpu/armv8/mach-thunderx or should I create a mach-thunderx directory directly under the cpu directory?
I'm assuming include files should go under arch/arm/include/asm/arch-thunderx.
I very much want to get this stuff pushed upstream so I don't run into the situation we've been stuck with our Octeon MIPS processors. My biggest problem is that a lot of code doesn't work.
I'm still trying to get up to speed with the armv8 U-Boot.

I personally prefer mach-thunderx over cpu/xxx/xxx. This is the newer "directory style" at least for armv7 or earlier platforms. With less directory levels to type.
I'm assuming include files should go under arch/arm/include/asm/arch-thunderx.
Or arch/arm/mach-thunderx/include/asm.

There should be many people on the list being able to assist with armv8 related questions.
Thanks, Stefan

Aaron,
I came across this post while searching for Octeon support.
Are you still working on this project? Are you also working on pushing up support for the Octeon TX? I have been pointed to a github repo for u-boot-81xx for support of the Octeon TX 80xx/81xx and am trying to determine what the state/timeline is for Octeon TX support in mainline u-boot. Unfortunately the git tree is not a fork/clone of mainline u-boot and instead is just a full directory push without history (why would someone even do that?) so it makes it difficult to see the extent of the patches.
Regards,
Tim
