+
+ - @pre
+ - If there is any driver which needs to run the callback function right before
+ issuing the reset, PCH Reset Callback Protocol will need to be installed
+ before PCH Reset Runtime DXE driver. If PchReset Runtime DXE driver is run
+ before Status Code Runtime Protocol is installed and there is the need
+ to use Status code in the driver, it will be necessary to add EFI_STATUS_CODE_RUNTIME_PROTOCOL_GUID
+ to the dependency file.
+ - @link _PCH_RESET_CALLBACK_PROTOCOL PCH_RESET_CALLBACK_PROTOCOL @endlink
+
+ - @result
+ The Reset driver produces @link _PCH_RESET_PROTOCOL PCH_RESET_PROTOCOL @endlink

+ <b>PchReset Runtime DXE Driver Entry Point</b>\n

+ The PchReset Runtime DXE driver provide a standard way for other modules to
+ use the PCH Reset Interface in DXE/SMM/Runtime environments. It has no longer
+ hooked ResetSystem() function of the runtime service table.
+
+ - @pre
+ - If there is any driver which needs to run the callback function right before
+ issuing the reset, PCH Reset Callback Protocol will need to be installed
+ before PCH Reset Runtime DXE driver. If PchReset Runtime DXE driver is run
+ before Status Code Runtime Protocol is installed and there is the need
+ to use Status code in the driver, it will be necessary to add EFI_STATUS_CODE_RUNTIME_PROTOCOL_GUID
+ to the dependency file.
+ - @link _PCH_RESET_CALLBACK_PROTOCOL PCH_RESET_CALLBACK_PROTOCOL @endlink
+
+ - @result
+ The Reset driver produces @link _PCH_RESET_PROTOCOL PCH_RESET_PROTOCOL @endlink

+ mDevIntConfig[] table contains data on INTx and IRQ for each device.
+ IRQ value for devices which use ITSS INTx->PIRQx mapping need to be set in a way
+ that for each multifunctional Dxx:Fy same interrupt pins must map to the same IRQ.
+ Those IRQ values will be used to update ITSS.PIRx register.
+ In APIC relationship between PIRQs and IRQs is:
+ PIRQA -> IRQ16
+ PIRQB -> IRQ17
+ PIRQC -> IRQ18
+ PIRQD -> IRQ19
+ PIRQE -> IRQ20
+ PIRQF -> IRQ21
+ PIRQG -> IRQ22
+ PIRQH -> IRQ23
+
+ Devices which use INTx->PIRQy mapping are: cAVS(in PCI mode), SMBus, GbE, TraceHub, PCIe,
+ SATA, HECI, IDE-R, KT Redirection, xHCI, Thermal Subsystem, Camera IO Host Controller
+
+ PCI Express Root Ports mapping should be programmed only with values as in below table (D27/28/29)
