* 3.10a srt 04/18/13 Implemented ARM Erratas. Please refer to file
|
||||
* 'xil_errata.h' for errata description
|
||||
* 4.2 pkp 06/19/14 Enabled asynchronous abort exception
|
||||
* 5.0 pkp 16/15/14 Modified initialization code to enable scu after
|
||||
* MMU is enabled
|

|

* @details
|
||||
*
|
||||
* The timer driver supports the Cortex A9 private timer.
|
||||
*
|
||||
* The timer driver supports the following features:
|
||||
* - Normal mode and Auto reload mode
|
||||
* - Interrupts (Interrupt handler is not provided in this driver. Application
|
||||
* has to register it's own handler)
|
||||
*
|
||||
* <b> Initialization and Configuration </b>
|
||||
*
|
||||
* The device driver enables higher layer software (e.g., an application) to
|
||||
* communicate with the Timer.
|
||||
*
|
||||
* XScuTimer_CfgInitialize() API is used to initialize the Timer. The
|
||||
* user needs to first call the XScuTimer_LookupConfig() API which returns
|
||||
* the Configuration structure pointer which is passed as a parameter to
|
||||
* the XScuTimer_CfgInitialize() API.
|
||||
*
|
||||
* <b> Interrupts </b>
|
||||
*
|
||||
* The Timer hardware supports interrupts.
|
||||
*
|
||||
* This driver does not provide a Interrupt Service Routine (ISR) for the device.
|
||||
* It is the responsibility of the application to provide one if needed. Refer to
|
||||
* the interrupt example provided with this driver for details on using the
|
||||
* Timer in interrupt mode.
|
||||
*
|
||||
* <b> Virtual Memory </b>
|
||||
*
|
||||
* This driver supports Virtual Memory. The RTOS is responsible for calculating
|
||||
* the correct device base address in Virtual Memory space.
|
||||
*
|
||||
* <b> Threads </b>
|
||||
*
|
||||
* This driver is not thread safe. Any needs for threads or thread mutual
|
||||
* exclusion must be satisfied by the layer above this driver.
|
||||
*
|
||||
* <b> Asserts </b>
|
||||
*
|
||||
* Asserts are used within all Xilinx drivers to enforce constraints on argument
|
||||
* values. Asserts can be turned off on a system-wide basis by defining, at
|
||||
* compile time, the NDEBUG identifier. By default, asserts are turned on and it
|
||||
* is recommended that users leave asserts on during development.
|
||||
*
|
||||
* <b> Building the driver </b>
|
||||
*
|
||||
* The XScuTimer driver is composed of several source files. This allows the user
|
||||
* to build and link only those parts of the driver that are necessary.
|
||||
*
|
||||
* <br><br>
|
||||
*
|
||||
* NOTE:
|
||||
* The timer is not a part of the snoop control unit as indicated by the
|
||||
* prefix "scu" in the name of the driver.
|
||||
* It is an independent module in APU.

* MODIFICATION HISTORY:
|
||||
*
|
||||
* Ver Who Date Changes
|
||||
* ----- --- -------- ---------------------------------------------
|
||||
* 1.00a nm 03/10/10 First release
|
||||
* 1.02a sg 07/17/12 Included xil_assert.h for CR 667947. This is an issue
|
||||
* when the xstatus.h in the common driver overwrites
|
||||
* the xstatus.h of the standalone BSP during the
|
||||
* libgen.
|
||||
* 2.1 sk 02/26/15 Modified the code for MISRA-C:2012 compliance.

|
||||
* (CR 702687)
|
||||
* Added support to direct interrupts to the appropriate CPU. Earlier
|
||||
* interrupts were directed to CPU1 (hard coded). Now depending
|
||||
* upon the CPU selected by the user (xparameters.h), interrupts
|
||||
* will be directed to the relevant CPU. This fixes CR 699688.
|
||||
*
|
||||
* 1.04a hk 05/04/13 Assigned EffectiveAddr to CpuBaseAddress in
|
||||
* XScuGic_CfgInitialize. Fix for CR#704400 to remove warnings.
|
||||
* Moved functions XScuGic_SetPriTrigTypeByDistAddr and
|
||||
* XScuGic_GetPriTrigTypeByDistAddr to xscugic_hw.c.
|
||||
* This is fix for CR#705621.
|
||||
* 1.06a asa 16/11/13 Fix for CR#749178. Assignment for EffectiveAddr
|
||||
* in function XScuGic_CfgInitialize is removed as it was
|
||||
* a bug.
|
||||
* 3.00 kvn 02/13/14 Modified code for MISRA-C:2012 compliance.
|
||||
* 3.01 pkp 06/19/15 Added XScuGic_InterruptMaptoCpu API for an interrupt
|
||||
* target CPU mapping

* @details
|
||||
*
|
||||
* The generic interrupt controller driver component.
|
||||
*
|
||||
* The interrupt controller driver uses the idea of priority for the various
|
||||
* handlers. Priority is an integer within the range of 1 and 31 inclusive with
|
||||
* default of 1 being the highest priority interrupt source. The priorities
|
||||
* of the various sources can be dynamically altered as needed through
|
||||
* hardware configuration.
|
||||
*
|
||||
* The generic interrupt controller supports the following
|
||||
* features:
|
||||
*
|
||||
* - specific individual interrupt enabling/disabling
|
||||
* - specific individual interrupt acknowledging
|
||||
* - attaching specific callback function to handle interrupt source
|
||||
* - assigning desired priority to interrupt source if default is not
|
||||
* acceptable.
|
||||
*
|
||||
* Details about connecting the interrupt handler of the driver are contained
|
||||
* in the source file specific to interrupt processing, xscugic_intr.c.
|
||||
*
|
||||
* This driver is intended to be RTOS and processor independent. It works with
|
||||
* physical addresses only. Any needs for dynamic memory management, threads
|
||||
* or thread mutual exclusion, virtual memory, or cache control must be
|
||||
* satisfied by the layer above this driver.
|
||||
*
|
||||
* <b>Interrupt Vector Tables</b>
|
||||
*
|
||||
* The device ID of the interrupt controller device is used by the driver as a
|
||||
* direct index into the configuration data table. The user should populate the
|
||||
* vector table with handlers and callbacks at run-time using the
|
||||
* XScuGic_Connect() and XScuGic_Disconnect() functions.
|
||||
*
|
||||
* Each vector table entry corresponds to a device that can generate an
|
||||
* interrupt. Each entry contains an interrupt handler function and an
|
||||
* argument to be passed to the handler when an interrupt occurs. The
|
||||
* user must use XScuGic_Connect() when the interrupt handler takes an
|
||||
* argument other than the base address.
|
||||
*
|
||||
* <b>Nested Interrupts Processing</b>
|
||||
*
|
||||
* Nested interrupts are not supported by this driver.
|
||||
*
|
||||
* NOTE:
|
||||
* The generic interrupt controller is not a part of the snoop control unit
|
||||
* as indicated by the prefix "scu" in the name of the driver.
|
||||
* It is an independent module in APU.

|
||||
* MODIFICATION HISTORY:
|
||||
*
|
||||
* Ver Who Date Changes
|
||||
* ----- ---- -------- ---------------------------------------------------------
|
||||
* 1.00a drg 01/19/00 First release
|
||||
* 1.01a sdm 11/09/11 The XScuGic and XScuGic_Config structures have changed.
|
||||
* The HandlerTable (of type XScuGic_VectorTableEntry) is
|
||||
* moved to XScuGic_Config structure from XScuGic structure.
|
||||
*
|
||||
* The "Config" entry in XScuGic structure is made as
|
||||
* pointer for better efficiency.
|
||||
*
|
||||
* A new file named as xscugic_hw.c is now added. It is
|
||||
* to implement low level driver routines without using
|
||||
* any xscugic instance pointer. They are useful when the
|
||||
* user wants to use xscugic through device id or
|
||||
* base address. The driver routines provided are explained
|
||||
* below.
|
||||
* XScuGic_DeviceInitialize that takes device id as
|
||||
* argument and initializes the device (without calling
|
||||
* XScuGic_CfgInitialize).
|
||||
* XScuGic_DeviceInterruptHandler that takes device id
|
||||
* as argument and calls appropriate handlers from the
|
||||
* HandlerTable.
|
||||
* XScuGic_RegisterHandler that registers a new handler
|
||||
* by taking xscugic hardware base address as argument.
|
||||
* LookupConfigByBaseAddress is used to return the
|
||||
* corresponding config structure from XScuGic_ConfigTable
|
||||
* based on the scugic base address passed.
|
||||
* 1.02a sdm 12/20/11 Removed AckBeforeService from the XScuGic_Config
|
||||
* structure.
|
||||
* 1.03a srt 02/27/13 Moved Offset calculation macros from *.c and *_hw.c to
|
||||
* *_hw.h
|
||||
* Added APIs
|
||||
* - XScuGic_SetPriTrigTypeByDistAddr()
|
||||
* - XScuGic_GetPriTrigTypeByDistAddr()
|
||||
* (CR 702687)
|
||||
* Added support to direct interrupts to the appropriate CPU. Earlier
|
||||
* interrupts were directed to CPU1 (hard coded). Now depending
|
||||
* upon the CPU selected by the user (xparameters.h), interrupts
|
||||
* will be directed to the relevant CPU. This fixes CR 699688.
|
||||
* 1.04a hk 05/04/13 Assigned EffectiveAddr to CpuBaseAddress in
|
||||
* XScuGic_CfgInitialize. Fix for CR#704400 to remove warnings.
|
||||
* Moved functions XScuGic_SetPriTrigTypeByDistAddr and
|
||||
* XScuGic_GetPriTrigTypeByDistAddr to xscugic_hw.c.
|
||||
* This is fix for CR#705621.
|
||||
* 1.05a hk 06/26/13 Modified tcl to export external interrupts correctly to
|
||||
* xparameters.h. Fix for CR's 690505, 708928 & 719359.
|
||||
* 2.0 adk 12/10/13 Updated as per the New Tcl API's
|
||||
* 2.1 adk 25/04/14 Fixed the CR:789373 changes are made in the driver tcl file.
|
||||
* 3.00 kvn 02/13/15 Modified code for MISRA-C:2012 compliance.

*
|

* ----- ---- -------- -------------------------------------------------------
|
||||
* 1.01a sdm 07/18/11 First release
|
||||
* 1.03a srt 02/27/13 Moved Offset calculation macros from *_hw.c (CR
|
||||
* 702687).
|
||||
* Added support to direct interrupts to the appropriate CPU.
|
||||
* Earlier interrupts were directed to CPU1 (hard coded). Now
|
||||
* depending upon the CPU selected by the user (xparameters.h),
|
||||
* interrupts will be directed to the relevant CPU.
|
||||
* This fixes CR 699688.
|
||||
* 1.04a hk 05/04/13 Fix for CR#705621. Moved functions
|
||||
* XScuGic_SetPriTrigTypeByDistAddr and
|
||||
* XScuGic_GetPriTrigTypeByDistAddr here from xscugic.c
|
||||
* 3.00 kvn 02/13/15 Modified code for MISRA-C:2012 compliance.

* 1.00a drg 01/19/10 First release
|
||||
* 1.01a sdm 11/09/11 "xil_exception.h" added as include.
|
||||
* Macros XScuGic_EnableIntr and XScuGic_DisableIntr are
|

* use an instance pointer but still wants to enable or
|
||||
* disable interrupts.
|
||||
* Function prototypes for functions (present in newly
|
||||
* added file xscugic_hw.c) are added.
|
||||
* 1.03a srt 02/27/13 Moved Offset calculation macros from *_hw.c (CR
|
||||
* 702687).
|
||||
* 1.04a hk 05/04/13 Fix for CR#705621. Moved function prototypes
|

* file requires other files of the driver to be linked in also.
|

*
|
||||
* The interrupt handler, XScuGic_InterruptHandler, uses an input argument which
|

* is an instance pointer to an interrupt controller driver such that multiple
|

* may be required.
|
||||
*
|
||||
* The interrupt processing may be used by connecting the interrupt handler to
|
||||
* the interrupt system. The handler does not save and restore the processor
|
||||
* context but only handles the processing of the Interrupt Controller. The user
|
||||
* is encouraged to supply their own interrupt handler when performance tuning is
