Difference between white & black script.bin

[Manoj Gudi]

It seems the difference is not just for touch_screen:

Can we truly have a single unified script.bin for all devices?

This whole script.bin thing is a massive hack (on linux-sunxi project's part.) They even had to patch the kernel to explicitly read their non-interoperable sunxi-specific script.bin code. Such hacks have been common in Linux-ARM world. Only recently has there been a successful effort to consolidate Linux across the diversity on ARM. I'm sure everyone would prefer a more portable approach.

Anyway, looking at the diff, I can see three patterns:

1) Differently coded, but semantically same values. e.g., "" vs <empty space>
2) Same keys, different values altogether.
3) Board specific keys.

#1 isn't a problem. As for #s 2 and 3, I propose a system of separating differing key-value pairs into board-specific files, and picking appropriate files at boot-time. Identifying the board can be done by a kernel, or by the bootloader.

Common sense dictates that if we're to have a single flashable image, we have to include a Union of all data required by all boards, in the image.

With union comes pain of intersection.

For ex:
-dram_clk = 408  => white
+dram_clk = 432  => black

I propose a separate namespace of each of devices; and union of all: like

black_dram_clk = 432

white_dram_clk = 408

Q: How will kernel know which namespace variables to load?

A: One variable which separates all the three tablets -> ctp_name

Check quoted content above.

Using ctp_name to identify board would still mean different script.bin for different boards, defeating the whole purpose.

That was impulsive and silly, sorry for the noise.
