* PcAtChipsetPkg: Add MMIO Support to RTC driverSami Mujawar2020-10-161-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | Some virtual machine managers like Kvmtool emulate the MC146818 RTC controller in the MMIO space so that architectures that do not support I/O Mapped I/O can use the RTC. This patch adds MMIO support to the RTC controller driver. The PCD PcdRtcUseMmio has been added to select I/O or MMIO support. If PcdRtcUseMmio is: TRUE - Indicates the RTC port registers are in MMIO space. FALSE - Indicates the RTC port registers are in I/O space. Default is I/O space. Additionally two new PCDs PcdRtcIndexRegister64 and PcdRtcTargetRegister64 have been introduced to provide the base address for the RTC registers in the MMIO space. When MMIO support is selected (PcdRtcUseMmio == TRUE) the driver converts the pointers to the RTC MMIO registers so that the RTC registers are accessible post ExitBootServices.

* PcAtChipsetPkg: add PcdRealTimeClockUpdateTimeoutRay Ni2019-09-041-3/+2
| | | | | | | | | | | | PcdRealTimeClockUpdateTimeout is now defined in MdeModulePkg.dec. This is the only reason that causes PcAtChipsetPkg depends on MdeModulePkg. Move the PCD from MdeModulePkg.dec to PcAtChipsetPkg.dec removes such dependency.

* PcAtChipsetPkg/PcRtc: Add two new PCD for RTC Index/Target registersRuiyu Ni2018-05-281-1/+3
| | | | | | | | | | | | | | | | | In certain HW implementation, the BIT7 of RTC Index register(0x70) is for NMI sources enable/disable but the BIT7 of 0x70 cannot be read before writing. Software which doesn't want to change the NMI sources enable/disable setting can write to the alias register 0x74, through which only BIT0 ~ BIT6 of 0x70 is modified. So two new PCDs are added so that platform can have the flexibility to change the default RTC register addresses from 0x70/0x71 to 0x74/0x75. With the new PCDs added, it can also support special HW that provides RTC storage in a different register pairs.

* PcAtChipsetPkg/Rtc: Fix a UEFI Win7 boot hang issueRuiyu Ni2015-12-221-0/+4
| | | | | | | | | | | | | | | | | | | | | The patch updates the Century value in CMOS location specified by FADT.Century to avoid UEFI Win7 hang during booting. Per the ACPI spec if the FADT.Century is zero, it's not needed to store the century value in CMOS. But UEFI Win7 treats the Century storage is optional only when FADT.Century is 0x80. While Linux strictly follows the ACPI spec and treats Century storage is optional when FADT.Century is 0. So if a platform wants to support both UEFI Win7 and Linux, it needs to report FADT.Century to a traditional value which doesn't equal to 0 or 0x80 (0x32 mostly). And RTC driver is enhanced to save the century value to the location specified by FADT.Century.
