Here are some macros to initialize the VIC:

#define paste(front, back)  front ## back

#define VIC_VECT_ADDR(slot, isr)     paste(VICVectAddr, slot) = 
(unsigned long) isr

#define VIC_VECT_CNTL(slot, channel) paste(VICVectCntl, slot) = 0x20 
| channel

#define VIC_INT_ENABLE(channel)      VICIntEnable = 0x00000001 << 
channel

// Slot definitions (lower number is higher priority)
#define VIC_SLOT_UART0               0
#define VIC_SLOT_UART1               1

// Channel definitions
#define VIC_CHANNEL_UART0            6
#define VIC_CHANNEL_UART1            7

Here is an example of how to use the macros:

VIC_VECT_ADDR(VIC_SLOT_UART0, Uart0Interrupt);
VIC_VECT_CNTL(VIC_SLOT_UART0, VIC_CHANNEL_UART0);
VIC_INT_ENABLE(VIC_CHANNEL_UART0);

This way you can keep your interrupt priorites in a separate file and 
change them transparently for different applications.
