Hi,
I answer your questions in detail.

Hi,
Wow, fast move, but need to more explanation.
what's the exact meaning of exynos4210?
Exynos4 is prefix and remaining are variants?
Quoted 7 lines
Exynos4210 means below.
1st digit means ARM core version. In this case, 4 means Cortex A9. (If we release cortex A15, it will be Exynos5xxx)
2nd digit means number of core. ?2 mean dual core.
3rd digit means application category(LSI internal category). 4th digit means design rule (generation or shrink version)
Nice, I want these rules.

Now you changed all s5pv310 to exynos4. if new exynos4xxx chip are comes then how to handle this one?
e.g., exynos4220 or later.
it's also conflict with mach-exynos4. do you handle all exynos4 series at this mach directory?
historically there's no rules of the base RAM address at least samsung chips.
Quoted 4 lines
Yes, we will handle all exynos4 series at mach-exynos4 directory. In the past, there is no rule.
But now, we are making consistent rules with AP design team. So, new version of exynos4 series will have same base RAM address.

Quoted 6 lines

Okay, no problem with base ram address,
Another one is how do you handle the GPIOs?
Now it's also changed as EXYNOS4_GPXX, I think it's difficult to use the same banks as exynos4210 has if new chips are introduced. maybe IRQ also has similar issue.

We already had reviewed your concern before. S5P6450 and S5P6440 is basically same processor. But GPIO, IRQ and some peripheral is little different. We can handle that by checking each processors chipid.

Please check the below patch.

Now these patches assumes all exynos4 has same gpios, irqs and so on.
How do you think about it?
Thank you,
