[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.
