[ipxe-devel] UEFI SCT patch

Hello,
I recently started working on our UEFI driver, and some of my changes
may be useful for iPXE upstream.
So here is a first patch dealing with NIC independent code. Can you have
a look and let me know if it needs some modifications.
It includes:
- changes to be more UEFI compliant and pass SCT tests (most changes
in efi_snp.c)
- initial support for the driver health protocol
- initial support for the firmware management protocol
You'll probably want to verify the additional checks for UEFI versions:
- I added the DRIVER_EFI_SUPPORTED_VERSION protocol, as required by
the UEFI spec.
" Provides information about the version of the EFI specification that a
driver is following. This
protocol is required for EFI drivers that are on PCI and other plug in
cards. "
- In efi_init.c I added a check for a minimal version of UEFI required
to use the driver. I am not sure you want to keep that.

+/** @file
+ EFI Driver Health Protocol definitions.
+
+ When installed, the Driver Health Protocol produces a collection of services that allow
+ the health status for a controller to be retrieved. If a controller is not in a usable
+ state, status messages may be reported to the user, repair operations can be invoked,
+ and the user may be asked to make software and/or hardware configuration changes.
+
+ The Driver Health Protocol is optionally produced by a driver that follows the
+ EFI Driver Model. If an EFI Driver needs to report health status to the platform,
+ provide warning or error messages to the user, perform length repair operations,
+ or request the user to make hardware or software configuration changes, then the
+ Driver Health Protocol must be produced.
+
+ A controller that is managed by driver that follows the EFI Driver Model and
+ produces the Driver Health Protocol must report the current health of the
+ controllers that the driver is currently managing. The controller can initially
+ be healthy, failed, require repair, or require configuration. If a controller
+ requires configuration, and the user make configuration changes, the controller
+ may then need to be reconnected or the system may need to be rebooted for the
+ configuration changes to take affect.

+/**
+ Updates the firmware image of the device.
+
+ This function updates the hardware with the new firmware image.
+ This function returns EFI_UNSUPPORTED if the firmware image is not updatable.
+ If the firmware image is updatable, the function should perform the following minimal validations
+ 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.
+
+ @param[in] This A pointer to the EFI_FIRMWARE_MANAGEMENT_PROTOCOL instance.
+ @param[in] ImageIndex A unique number identifying the firmware image(s) within the device.

+ @param[in] ImageSize Size of the new image in bytes.
+ @param[in] VendorCode This enables vendor to implement vendor-specific firmware image update policy.
+ Null indicates the caller did not specify the policy or use the default policy.
+ @param[in] Progress A function used by the driver to report the progress of the firmware update.

+ details for the aborted operation. The buffer is allocated by this function
+ with AllocatePool(), and it is the caller's responsibility to free it with a
