As I said above, that's not the problem, the problem is merging it into
the rest of my tree.
Having done most of that merge, I'm now tripping up on:
arch/arm/mach-dove/common.c: In function 'dove_wdt_init':
arch/arm/mach-dove/common.c:538:2: error: implicit declaration of function 'orion_wdt_init' [-Werror=implicit-function-declaration]
which I guess is because you've deleted the legacy orion watchdog stuff.
So I'm going to have to revert that. That then gives me:
arch/arm/mach-dove/clock.c:19:21: fatal error: mach/pm.h: No such file or directory
arch/arm/mach-dove/clock.c:20:27: fatal error: mach/hardware.h: No such file or directory
The first is easy to solve, and the second by replacing it with dove.h.
The next problem is this:
arch/arm/plat-orion/common.c:25:30: fatal error: mach/bridge-regs.h: No such file or directory
which is impossible to solve, because plat-orion/common.c wants
I also have arch/arm/mach-dove/include/mach/sdhci.h to pass the GPIO
for card detection to the SDHCI driver, which is going to break unless
it's moved to include/linux/platform-data.
Everything else seems mostly happy, but I've no way to tell whether
what would be the resulting kernel would work as it's impossible to
know without fixing the wreckage above.
I'm sure I don't have to repeat my position over what I'm going to do if
these petty mainline changes which are totally unnecessary break the only
setup I have which works. Making mach-dove multi-platform is a "wouldn't
it be nice if", it's not an absolute necessity.

according to speedtest.net.
