c974ab0ecb efi_loader: ListPackageLists() return EFI_NOT_FOUND
If no matching package list is found in ListPackageLists(), return
EFI_NOT_FOUND.

If we do not support a package type, we will not find a matching package
list. Remove the unreachable EFI_PRINTF() statements.

1a9fce5039 efi_loader: HII protocols: debug messages
When package types are not supported by our implementation of the HII
database protocol supported error messages are displayed.

Essentially the output is only needed for debugging. By using EFI_PRINT()
the messages are only written for in debug mode and with correct
indentation.

fdef298338 efi_loader: HII protocols: fix new_package_list()
In new_package_list() we call new_packagelist() to create a new package
list. Next we try to add the packages which fails for form packages. Due
to this error we call free_packagelist(). Now in free_packagelist()
list_del() is called for an uninitialized field hii->link. This leads to
changing random memory addresses.

To solve the problem move the initialization of hii->link to
new_packagelist().

6f8f4217e7 efi_loader: debug output for HII protocols
For correct indention use EFI_PRINT() instead of debug().

For printing efi_uintn_t or size_t use the %zu or %zx format code.

8d3b77e36e efi: hii: add keyboard layout package support
Allow for handling keyboard layout package in HII database protocol.

A package can be added or deleted in HII database protocol, but
we don't set 'current' keyboard layout as there is no driver that
requests a keyboard layout.

c9bfb22296 efi_loader: Initial HII database protocols
This patch provides enough implementation of the following protocols to
run EDKII's Shell.efi and UEFI SCT:

  * EfiHiiDatabaseProtocol
  * EfiHiiStringProtocol

Not implemented are:
  * ExportPackageLists()
  * RegisterPackageNotify()/UnregisterPackageNotify()
  * SetKeyboardLayout() (i.e. *current* keyboard layout)

HII database protocol in this patch series can handle only:
  * GUID package
  * string package
  * keyboard layout package
  (The other packages, except Device path package, will be necessary
   for interactive and graphical UI.)
