CONFIG_SYS_HZ fix for ARM902T S3C24X0 Boards
This sets CONFIG_SYS_HZ to 1000 for all boards that use the s3c2400 and
s3c2410 cpu's which fixes various problems such as the timeouts in tftp being
too short.
Tested on an Embest SBC2440-II Board with local u-boot patches as I don't
have any s3c2400 or s3c2410 boards but need this patch applying before I can
submit patches for the SBC2440-II Board. Also, ran MAKEALL for all ARM9 targets
and no new warnings or errors were found.
It was originally submitted on 21/06/2009 but didn't get into the 2009.08
release, and Jean-Pierre made one comment on the original patch (see
http://lists.denx.de/pipermail/u-boot/2009-July/055470.html). I've made two
changes to the original patch:
- it's been re-based to the current release
- I've re-named get_timer_raw() to get_ticks() in response to Jean-Pierre's comment
This affects the sbc2410, smdk2400, smdk2410 and trab boards. I've copied it
directly to the maintainers of all except the sbc2410 which doesn't have an
entry in MAINTAINERS.
