Yahuen, let me know if you've any objection to this going upstrea. Forgot to add --compose to send-email, so here's what should have gone into the first email of this series: S3C2416 support, mainly just processor core and a few peripheral setup patches. Also has basic support for the S3C2450 which is very similar SoC which will be updated later in the series. Currently based on the s3c24xx gpio series.
