- ***** INTRODUCTION ***********
|
|
|
- * On the Blackfin, the interrupt structure allows remmapping of the hardware
|
|
|
- * levels.
|
|
|
- * - I'm going to assume that the H/W level is going to stay at the default
|
|
|
- * settings. If someone wants to go through and abstart this out, feel free
|
|
|
- * to mod the interrupt numbering scheme.
|
|
|
- * - I'm abstracting the interrupts so that uClinux does not know anything
|
|
|
- * about the H/W levels. If you want to change the H/W AND keep the abstracted
|
|
|
- * levels that uClinux sees, you should be able to do most of it here.
|
|
|
- * - I've left the "abstract" numbering sparce in case someone wants to pull the
|
|
|
- * interrupts apart (just the TX/RX for the various devices)
