1. After wake-up, the system-wide flags register loses its value.
Hence, write the address of secondary startup function to
successfully boot the secondary CPU.
2. Changes SGI1 to SGI0 for secondary CPU boot up

. as you know C210 EVT0 OneNAND DMA has
bug and need to workaround.
platform codes should provide the these function. please see the OMAP
codes. how to handle it.
Thank you,

I'd like the use of the arbitary SGI1 to fade away, to be replaced with

For this one you are avoiding a wakeup IPI and rather
relying on schedule IPI. That just avoiding the issue.
This doesn't seems to be right. Refer below threa

e's little
else we can do than poke both locations and pray.
Is there such a way to identify the SoC revision?

Subject: [PATCH] ARM: exynos4: fix secondary CPU boot on early SoC revisions
It appears that the system-wide flags register that used to be at
0x02025000 on the
address has changed between two SoC revisions? That's
unfortunate, to say the least. I'm most probably using an early revision
of the hardware (EVT0?), as it doesn't even support MCT.
What about the following patch?
