V2: accepted comments I got on V1; rewritten the driver to be generic;
made it tristate instead of boolean. Rebased on new next.
This patch set introduces use of AMBA devices under a PCI bridge.
The device table in the driver include all the devices that we'll be
able to run using AMBA drivers.
To compile AMBA under x86, though I need <asm/sizes.h>,
which is moved to <linux/sizes.h> as suggested earlier.
I'm hereby volunteering to handle the moving of the various users
of <asm/sizes.h> to <linux/sizes.h>; this set only moves the ARM core
files and the ones that I need under x86.
The whole patch set is sent to the same set of recipients:
all relevant lists, Russell King (for arm), Greg-KH (for uart) and
Arnd Bergmann (for generic include).
With this set in place (plus a clok API not included here) I have
4 serial ports working.

This looks good to me.
Acked-by: Linus Walleij <linus.walleij@linaro.org>
I think this patch set could go through Arnd as arch maintainer?
It's fun with these cross-arch things. You'll need an ACK from
Russell first.
Yours,

I don't think it has much to do with code I maintain. Russell
as the Primecell maintainer is the right person to take it through
his tree.

Russell, is there some action I shall take? I suspect your email-based
patch system is over by now, or should I send patches in there?
thanks
