<asm-generic/div64.h> isn't meant for direct usage as <asm/div64.h> may
override this on a per-architecture basis. We don't do that currently,
but in the future we might. Include the <linux/math64.h> instead.
No functional change.

From: Ahmad Fatoum @ 2021-02-16 18:57 UTC (permalink / raw)
To: barebox; +Cc: Ahmad Fatoum
barebox implements do_div() as soft division unconditionally, even on
64-bit platforms that could use hardware 64-bit division directly.
Import the whole Linux asm-generic/div64.h header to avoid this.
This also has potential positive effect on 32-bit platforms:
64-bit division with constant divisors can now be optimized into
multiplications and shifts at compile time.

To: barebox; +Cc: Ahmad Fatoum
f933da28cf3f ("include: <linux/math64.h>: sync with upstream") imported
the div64 code from Linux, which also defines __div64_32 as a weak
symbol. __div64_32 was defined before in a separate file though and used
from do_div. Remove this duplication.
No functional change.
