Add stubs for UpdateCapsule, QueryCapsuleCapabilities, and
QueryVariableInfo.Signed-off-by: Heinrich Schuchardt
Signed-off-by: Alexander Graf -
Currently we set the function pointer for the CreateEventEx boot service
to NULL. When called this would lead to an immediate failure.A function stub is provided which handles the case that the boot service
is called without an event group and returns EFI_UNSUPPORTED otherwise.Signed-off-by: Heinrich Schuchardt

This patch lets the implementation of ExitBootServices conform to
the UEFI standard.The timer events must be disabled before calling the notification
functions of the exit boot services events.The boot services must be disabled in the system table.
The handles in the system table should be defined as efi_handle_t.

Consistenly use efi_uintn_t wherever the UEFI spec uses
UINTN in boot services interfaces.Signed-off-by: Heinrich Schuchardt
Signed-off-by: Alexander Graf -
UINTN is used in the UEFI specification for unsigned integers
matching the bitness of the CPU.Types in U-Boot should be lower case. The patch replaces it
by efi_uintn_t.Suggested-by: Simon Glass

Shell.efi uses this, and supporting color attributes makes things look
nicer. Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".Signed-off-by: Rob Clark

The returned interrupt status was wrong.
As out transmit buffer is empty we need to always set

The UEFI spec defines parameter index of WaitForEvent as UINTN*.

Similar to a "real" UEFI implementation, the bootmgr looks at the
BootOrder and BootXXXX variables to try to find an EFI payload to load
and boot. This is added as a sub-command of bootefi.The idea is that the distro bootcmd would first try loading a payload
via the bootmgr, and then if that fails (ie. first boot or corrupted
EFI variables) it would fallback to loading bootaa64.efi. (Which
would then load fallback.efi which would look for \EFI\*\boot.csv and
populate BootOrder and BootXXXX based on what it found.)Signed-off-by: Rob Clark
Signed-off-by: Alexander Graf -
fallback.efi (and probably other things) use UEFI's simple-file-system

It needs to handle more device-path node types, and also multiple levels
of path hierarchy. To simplify this, initially construct utf8 string to
a temporary buffer, and then allocate the real utf16 buffer that is
returned. This should be mostly for debugging or at least not critical-
path so an extra copy won't hurt, and is saner than the alternative.Signed-off-by: Rob Clark
