[coreboot-gerrit] [XS] Change in coreboot[main]: sandybridge,haswell,broadwell: Use DIV_ROUND_CLOSEST macro

[Angel Pons (Code Review)]

Attention is currently required from: Angel Pons.

Hello Arthur Heymans, Nico Huber, Patrick Rudolph, build bot (Jenkins),

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/52651?usp=email

to look at the new patch set (#4).

sandybridge,haswell,broadwell: Use DIV_ROUND_CLOSEST macro

Integer division in C truncates toward zero. When the dividend and the
divisor are positive, one can add half of the divisor to the dividend to
round the division result towards the closest integer. We already have a
macro in commonlib to do just that, so put it to good use.

Tested with BUILD_TIMELESS=1, coreboot images for the Asus P8Z77-V LX2
and the Asrock B85M Pro4 do not change.
