The current kernel is not very well tuned for OMAP 2420 since it

Userspace was the

An update to the slow boot: current from Aug 5th 2008 boots in 23
seconds. Changes since then have slowed the kernel considerably
on OMAP
2420.
Just as a datapoint, this isn't generic to all the evbarm targets;
my PXA250
boots an INSTALL kernel (gzip'ed, with ramdisk) from WinCE in
35-40 sec, and
from the point of the 2nd-stage loader handing control to the
kernel it's ~ 5
sec to sysinst running.
