Hello,
Since I've been supporting a u-boot for the Renesas RZ/A1 SoC for a while now, I thought I'd start upstreaming the drivers/patches I've
acquired
over the years.
But, where should the core files and Kconfig go?
The RZ/A1 series has a Cortex-A9.
At first, I had made a directory under arch/arm/cpu/armv7/
But, now I see things are moving under arch/arm/mach-xxxx.
There is a arch/arm/mach-rmobile directory that has the Renesas R-Car devices. But while the RZ/A1 uses some of the same HW IP blocks, for the most part it's a different product line.
So, Where should I put my RZ/A1 (and future RZ/A devices, or future RZ/N devices)?
- Keep all Renesas parts together like we do in the kernel (arm/mach-
shmobile)?
u-boot/arch/arm/mach-rmobile
I would vote for renaming and matching the kernel here and using mach-shmobile. Thanks!
Ugh! That shmobile name is going to haunt us forever (even though we don't even make SH-Mobile parts anymore....and they are all ARM cores now, not SH).
I will say that upstream in the kernel, most everything else has been renamed to "renesas" (ie, ARCH_RENESAS, )...except that directory name. I asked if/when they would rename it, but at the moment, there is not plan as not to break anything.
Maybe we can compromise on everything in mach-renesas??
OK, I can go with mach-renesas, thanks again!
