Subject: [U-Boot] [PATCH] Coldfire M5271: Activate u-boot system timer interrupt.
Date: Thu, 26 Mar 2009 15:30:32 -0400 [thread overview]

Subject: [PATCH] Coldfire M5271: Activate u-boot system timer interrupt.
This patch assigns the u-boot system timer interrupt to
interrupt level 3, priority 6. Without this patch the interrupt
will be a level 0, priority 0, which disables it and cause
u-boot functions that relies on the timer (e.g. sleep command)
to never return.
