Somebody in the thread at some point said:

to lcm?

| Ah, I think I see what you mean. I could convert the LCD data lines,
| VD0..23 into gpio and then I would have enough pins. Ah, yes, this
| will work. I had forgotten that S3C2410's VD lines are multifunction.

The LCD bus is coming out of the Glamo, not the CPU on GTA02.

There's other confusion in what you wrote, s3c2410 is GTA01 CPU, s3c2442
is GTA02 and s3c6410 will be GTA03.  GTA02 alone has the Glamo running
the LCM.

There is a command / bypass capability inGLamo LCD controller to send
commands to smart LCD, maybe it can match the needs of the E-ink
controller since it's a common async memory bus kind of deal then.
