2) The s3c2440 user manual provides at full reference

the application processor. If you're willing to re-configure some of
the internal PLLs, then you can achieve baud rates up to 921.6kbps.
So I'm quite sure using the s3c2440 manual you can compute a PCLK
suitable for the non-standard high baudrate of burst_ind, and then
compute PLL parameters for ensuring the s3c2440 PLL generates that
PCLK.

Note that it probably didn't go into mainline according to the comments
of this patch.
Also do higer baudrates require an external clock(I didn't check in
the SC32442B datasheet)? (and I guess the GTA02 has an internal
clock,but I didn't check myself on the schematics).
