Patch 7d30e8b38 (ARM: EXYNOS4: Add EXYNOS4 CPU initialization support) renamed the s5pv310 to exynos4, and also changed the value of EXYNOS4_PA_SYSRAM, which is used to release the secondary CPU from spinning in BL0. As a result, CPU1 can't be brought up anymore. This patch simply reverts EXYNOS4_PA_SYSRAM to its original value, which results in a working CPU1. Tested on an SMDK-v310.

Hi Marc, Hmm...the value, 0x02020000 is correct on Exynos4210 now. So can't apply this but I know, you're right on old version of Exynos4210...let's think again about this. Maybe I missed its commit for changing when I submitted it...
