[edk2-devel] [PATCH 1/2] Retire CorebootModulePkg from EDK2

Tue May 7 22:27:27 UTC 2019
Since UefiPayloadPkg in EDK2 supports Coreboot and Slim Bootloader, and I don't
receive any concerns for the RFC to remove CorebootModulePkg and
CorebootPayloadPkg from EDK2 (https://edk2.groups.io/g/devel/message/39126),
here is the action patch to remove CorebootModulePkg.

-/**
- Returns the information about the optimum modes for the specified IDE device.
-
- This function is used by the driver entity to obtain the optimum ATA modes for
- a specific device. The IDE controller driver takes into account the following
- while calculating the mode:
- - The IdentifyData inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- - The BadModes inputs to EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode()
-
- The driver entity is required to call EFI_IDE_CONTROLLER_INIT_PROTOCOL.SubmitData()
- for all the devices that belong to an enumeration group before calling
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.CalculateMode() for any device in the same group.
-
- The IDE controller driver will use controller- and possibly platform-specific
- algorithms to arrive at SupportedModes. The IDE controller may base its
- decision on user preferences and other considerations as well. This function
- may be called multiple times because the driver entity may renegotiate the mode
- with the IDE controller driver using EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode().
-
- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
-
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
-
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a
- second-generation [Gen2]-capable hardware). The IDE controller driver can
- also allow the driver entity to stay with the speed that has been negotiated
- by the physical layer.

- The driver entity may collect timing information for various devices in any
- order. The driver entity is responsible for making sure that all the dependencies
- are satisfied. For example, the SupportedModes information for device A that
- was previously returned may become stale after a call to
- EFI_IDE_CONTROLLER_INIT_PROTOCOL.DisqualifyMode() for device B.
-
- The buffer SupportedModes is allocated by the callee because the caller does
- not necessarily know the size of the buffer. The type EFI_ATA_COLLECTIVE_MODE
- is defined in a way that allows for future extensibility and can be of variable
- length. This memory pool should be deallocated by the caller when it is no
- longer necessary.
-
- The IDE controller driver for a Serial ATA (SATA) controller can use this
- member function to force a lower speed (first-generation [Gen1] speeds on a
- second-generation [Gen2]-capable hardware). The IDE controller driver can
- also allow the driver entity to stay with the speed that has been negotiated
- by the physical layer.
-
- @param[in] This The pointer to the EFI_IDE_CONTROLLER_INIT_PROTOCOL instance.
- @param[in] Channel A zero-based channel number.
- @param[in] Device A zero-based device number on the Channel.

- @retval EFI_SUCCESS SupportedModes was returned.
- @retval EFI_INVALID_PARAMETER Channel is invalid (Channel >= ChannelCount).
- @retval EFI_INVALID_PARAMETER Device is invalid.
