+ * 1) We handle one interrupt and return, sitting in a loop and moving across

+ *
+ * 2) We need not check against bits in the status register IRQ mask, that
+ *    would make this routine slow as hell.
+ *
+ * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
+ *    between like BSD spl() brain-damage.
+ *
+ * Furthermore, the IRQs on the MIPS board look basically (barring software
+ * IRQs which we don't use at all and all external interrupt sources are
+ * combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
+ *
+ *	MIPS IRQ	Source
+ *      --------        ------
+ *             0	Software (ignored)
+ *             1        Software (ignored)

+ *             7        R4k timer (what we use)
+ *
+ * Note: On the SEAD board thing are a little bit different.
+ *       Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
+ *       wired to UART1.
+ *
+ * We handle the IRQ according to _our_ priority which is:
+ *
+ * Highest ----     R4k Timer
+ * Lowest  ----     Combined hardware interrupt
+ *
+ * then we just return, if multiple IRQs are pending then we will just take

+ * FILE PURPOSE:    TNETD73xx Common Header File
+ ******************************************************************************
+ * FILE NAME:       tnetd73xx.h
+ *
+ * DESCRIPTION:     shared typedef's, constants and API for TNETD73xx
+ *
+ * REVISION HISTORY:
+ * 27 Nov 02 - PSP TII  
+ *
+ * (C) Copyright 2002, Texas Instruments, Inc
+ *******************************************************************************/
+
+/*
+ *
+ *
+ *   These are const, typedef, and api definitions for tnetd73xx.
+ *
+ *   NOTES:
+ *   1. This file may be included into both C and Assembly files.
+ *       - for .s files, please do #define _ASMLANGUAGE in your ASM file to
+ *           avoid C data types (typedefs) below;
+ *       - for .c files, you don't have to do anything special.
+ *
+ *   2. This file has a number of sections for each SOC subsystem. When adding
+ *       a new constant, find the subsystem you are working on and follow the
+ *       name pattern. If you are adding another typedef for your interface, please,
+ *       place it with other typedefs and function prototypes.
+ *
+ *   3. Please, DO NOT add any macros or types that are local to a subsystem to avoid
+ *       cluttering. Include such items directly into the module's .c file or have a
+ *       local .h file to pass data between smaller modules. This file defines only
+ *       shared items.
