ARM: S3C24XX: move s3c24xx_init_irq to s3c2410_init_irq
From: Heiko Stuebner <heiko@...> Date: Thu, 21 Feb 2013 02:02:03 +0100
Commit-Message
The s3c24xx_init_irq function that was the base for all irq inits is now only used to initialize the real s3c2410 irqs. Therefore rename it and also move its declaration from plat/cpu.h to common.h The eint declaration is used by the vast majority of the SoCs and gets therefore placed outside any ifdefs.
