Kukjin,

What about the legacy board files? I don't see them removed (nor converted to
DT) here, so this is not a full removal.

Also, the argument to keep exynos4_defconfig was that it needed to enable non-DT boards. I think we might as well just remove the defconfig and make sure
all the needed options are enabled in exynos_defconfig -- they should coexist
just fine.

I'll hold off pulling until the defconfig situation has been resolved, but please follow up on the board file piece too.

After exynos has been converted to DT-only booting by removing most a lot of the ATAGS code, I had a closer look of what is left. It turns out that a number of unused files are left in the tree that can be removed along with about another quarter of the remaining code in mach-exynos.

Specifically this includes:

* all board files
* all setup-*.c files
* dev-audio.c and dev-uart.c
* all code testing for of_have_populated_dt
* the eint_irqchip
* almost all the mach/irqs.h constants (the remaining ones are likely bugs)
* Most physical address constants. The remaining ones are either bugs or used for the iotable. Both can probably get removed in the long run.
* regs-usb-phy.h, which was already unused before
* A lot of code in plat-samsung/ can be made conditional on CONFIG_ATAGS, in particular now unused device definitions.

Hi Kukjin,

Could you check the validity of this patch please?

I think we should apply it on top of your series. I've generated the patch using 'git format-patch -D' for brevity, so be careful to actually delete the unused files if you want to apply it to a local branch on your side.

Great. This is the piece that I wanted to see in the non-DT-removal branch before I pulled it.

Yeah, I think so. But as Arnd suggested, I'm looking at Tomasz's patches and it will be sorted out in this weekend.
