3 * EFI capsule support.
33 * efi_capsule_pending - has a capsule been passed to the firmware?
34 * @reset_type: store the type of EFI reset if capsule is pending
36 * To ensure that the registered capsule is processed correctly by the
37 * firmware we need to perform a specific type of reset. If a capsule is
62 * Whitelist of EFI capsule flags that we support.
73 * efi_capsule_supported - does the firmware support the capsule?
74 * @guid: vendor guid of capsule
75 * @flags: capsule flags
76 * @size: size of capsule data
77 * @reset: the reset type required for this capsule
79 * Check whether a capsule with @flags is supported by the firmware
80 * and that @size doesn't exceed the maximum size for a capsule.
