Bug 1996 - Contribution for West Bridge Astoria Symbian Storage Driver
this storage driver is for the West Bridge Astoria chipset. This device
has a USB, SD and processor port for communication with a baseband processor.
In our port, we connected this device DVK to the Beagleboard through the SPI
interface of the OMAP3. After driver installation, the Symbian OS can see an
external device or D: drive represented by the SD card. In this driver, the USB
interface is not used directly, though this may be the subject of future
contributions. The appropriate way to test the driver is to access the external
volume and do file read and write to it, pretty much the same way you would
test a thumb drive on your PC

/* Summary
Initialize the interrupt manager module
Description
This function is called to initialize the interrupt module. This module enables interrupts
as well as servies West Bridge related interrupts by determining the source of the interrupt and
calling the appropriate handler function.
Notes
If the dmaintr parameter is TRUE, the initialization code initializes the interrupt mask to
have the DMA related interrupt enabled via the general purpose interrupt. However, the interrupt
service function assumes that the DMA interrupt is handled by the HAL layer before the interrupt
module handler function is called.
Returns
* CY_AS_ERROR_SUCCESS - the interrupt module was initialized correctly
* CY_AS_ERROR_ALREADY_RUNNING - the interrupt module was already started
See Also
* CyAsIntrStop
* CyAsServiceInterrupt

/* Summary
Stop the interrupt manager module
Description
This function stops the interrupt module and masks all interrupts from the West Bridge device.
Returns
* CY_AS_ERROR_SUCCESS - the interrupt module was stopped sucessfully
* CY_AS_ERROR_NOT_RUNNING - the interrupt module was not running

/* Summary
The interrupt service routine for West Bridge
Description
When an interrupt is detected, this function is called to service the West Bridge interrupt. It is safe
and efficient for this function to be called when no West Bridge interrupt has occurred. This function
will determine it is not an West Bridge interrupt quickly and return.
