- This function returns EFI_UNSUPPORTED if the firmware image is not updatable.

- before proceeding to do the firmware image update.
- - Validate the image authentication if image has attribute
- IMAGE_ATTRIBUTE_AUTHENTICATION_REQUIRED. The function returns
- EFI_SECURITY_VIOLATION if the validation fails.
- - Validate the image is a supported image for this device. The function returns EFI_ABORTED if
- the image is unsupported. The function can optionally provide more detailed information on
- why the image is not a supported image.
- - Validate the data from VendorCode if not null. Image validation must be performed before
- VendorCode data validation. VendorCode data is ignored or considered invalid if image
- validation failed. The function returns EFI_ABORTED if the data is invalid.
-
- VendorCode enables vendor to implement vendor-specific firmware image update policy. Null if
- the caller did not specify the policy or use the default policy. As an example, vendor can implement
- a policy to allow an option to force a firmware image update when the abort reason is due to the new
- firmware image version is older than the current firmware image version or bad image checksum.
- Sensitive operations such as those wiping the entire firmware image and render the device to be
- non-functional should be encoded in the image itself rather than passed with the VendorCode.
- AbortReason enables vendor to have the option to provide a more detailed description of the abort
- reason to the caller.

- AllocatePool(), and it is the caller's responsibility to free it with a
- call to FreePool().
- @param[out] PackageVersionNameMaxLen The maximum length of package version name if device supports update of
- package version name. A value of 0 indicates the device does not support
- update of package version name. Length is the number of Unicode characters,
- including the terminating null character.
- @param[out] AttributesSupported Package attributes that are supported by this device. See 'Package Attribute
- Definitions' for possible returned values of this parameter. A value of 1
- indicates the attribute is supported and the current setting value is
- indicated in AttributesSetting. A value of 0 indicates the attribute is not

- before proceeding to do the firmware image update.
- - Validate the image authentication if image has attribute

- EFI_SECURITY_VIOLATION if the validation fails.
- - Validate the image is a supported image for this device. The function returns EFI_ABORTED if

- the caller did not specify the policy or use the default policy. As an example, vendor can implement
- a policy to allow an option to force a firmware image update when the abort reason is due to the new
- firmware image version is older than the current firmware image version or bad image checksum.
- Sensitive operations such as those wiping the entire firmware image and render the device to be

-# Components Section - list of the modules and components that will be processed by compilation
-# tools and the EDK II tools to generate PE32/PE32+/Coff image files.
-#
-# Note: The EDK II DSC file is not used to specify how compiled binary images get placed
-# into firmware volume images. This section is just a list of modules to compile from
-# source into UEFI-compliant binaries.
-# It is the FDF file that contains information on combining binary files into firmware
-# volume images, whose concept is beyond UEFI and is described in PI specification.
-# Binary modules do not need to be listed in this section, as they should be
-# specified in the FDF file. For example: Shell binary (Shell_Full.efi), FAT binary (Fat.efi),
-# Logo (Logo.bmp), and etc.
-# There may also be modules listed in this section that are not required in the FDF file,
-# When a module listed here is excluded from FDF file, then UEFI-compliant binary will be
-# generated for it, but the binary will not be put into any firmware volume.
