HI All,
I am new to this group. I am working on Freescale P2020
platform running linux 2.6.21. I am looking for debug mechanism/utility,
when a multi threaded application running on linux , appears to be hung (
running in a tight loop,deadlock) while not able to access the board

Previously in order to handle the edge sensitive decrementers,
we choose to set the decrementer to 1 to trigger a decrementer
interrupt when re-enabling interrupts. But with the rework of the
lazy EE, we would replay the decrementer interrupt when re-enabling
interrupts if a decrementer interrupt
We remove the redundant tdi_reset in ehci_setup since there
is already it in ehci_reset.
It was observed that the duplicated tdi_reset was causing
the PHY_CLK_VALID bit unstable.

Because the logic of the comment applies to the else-condition, not the

The firmware should have supplied correct information for the kernel

Otherwise, the kernel will fail back to use solely 4KB page size
