[PATCH] ARM: exynos4: use the variable for S5P_VA_SYSRAM

[PATCH] ARM: exynos4: use the variable for S5P_VA_SYSRAM

[Kyungmin Park]

From: Kyungmin Park <kyungmin.park@samsung.com>

The CPU1_BOOT_REG and S5P_VA_SYSRAM is used mixed for setup secondary_startup.
Make it consistent statement for setup.

It's also helpful for EVT0 which has another SYSRAM address handling.

	if (soc_is_exynos4210_evt0())
		sysram = ioremap(EXYNOS4210_EVT0_SYSRAM, SZ_4K);
