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

42 | * Adding an interrupt service routine for a source with this bit | ||
43 | * set indicates a special machine specific interrupt source. | ||
44 | * The machine specific files define these sources. | ||
45 | * | ||
46 | * The IRQ_MACHSPEC bit is now gone - the only thing it did was to | ||
47 | * introduce unnecessary overhead. | ||
48 | * | ||
49 | * All interrupt handling is actually machine specific so it is better | ||
50 | * to use function pointers, as used by the Sparc port, and select the | ||
51 | * interrupt handling functions when initializing the kernel. This way | ||
52 | * we save some unnecessary overhead at run-time. | ||
