xapp902 with 2.6.17 -- uartlite & ramdisk problems

[robert corley <rdcorle@yahoo.com>]

All;=0A=0AAs the below shows, the ramdisk problem has been circumvented by =
use of the cmdline option ramdisk_size=3D4660000.=0A=0AStill experience ter=
ribly slow uart.  Can anyone quickly point me to the appropriate interrupt =
components for the uartlite et al?=0A=0ASome other questions:=0A=0A1.   Are=
 interrupts obtained via the platform_get_resource() call?=0A2.   Are alloc=
ated interrupts issued starting at 0?=0A3.    Is there a correlation betwee=
n the xparameters_ml403.h entries below and the interrupt issued in 1, abov=
