- If you are compiling a kernel for a NetWinder or EBSA-285, you will
- be able to select which LEDs are active using the options below. If
- you are compiling a kernel for the EBSA-110 or the LART however, the
- red LED will simply flash regularly to indicate that the system is
- still functional. It is safe to say Y here if you have a CATS

- If you say Y here, one of the system LEDs (the green one on the
- NetWinder, the amber one on the EBSA285, or the red one on the LART)
- will flash regularly to indicate that the system is still
- operational. This is mainly useful to kernel hackers who are

- The LART uses the same LED for both Timer LED and CPU usage LED
- functions. You may choose to use both, but the Timer LED function
- will overrule the CPU usage LED.

- * Interrupt Handler for L3 error detection.
- * 1) Identify the L3 clockdomain partition to which the error belongs to.
- * 2) Identify the slave where the error information is logged
- * 3) Print the logged information.
- * 4) Add dump stack to provide kernel trace.
- *
- * Two Types of errors :
- * 1) Custom errors in L3 :
- * Target like DMM/FW/EMIF generates SRESP=ERR error
- * 2) Standard L3 error:
- * - Unsupported CMD.
- * L3 tries to access target while it is idle
- * - OCP disconnect.
- * - Address hole error:
- * If DSS/ISS/FDIF/USBHOSTFS access a target where they
- * do not have connectivity, the error is logged in
- * their default target which is DMM2.
- *
- * On High Secure devices, firewall errors are possible and those
- * can be trapped as well. But the trapping is implemented as part
- * secure software and hence need not be implemented here.
