The existing options, "--fit" and "--raw," are only used to put a proper GUID in a capsule header, where GUID identifies a particular FMP (Firmware Management Protocol) driver which then would handle the firmware binary in a capsule. In fact, mkeficapsule does the exact same job in creating a capsule file whatever the firmware binary type is. To prepare for the future extension, the command syntax will be a bit modified to allow users to specify arbitrary GUID for their own FMP driver.

.SH SYNOPSIS

|

.RI [ options "] " image-blob " " capsule-file
|
|
|
|
.SH "DESCRIPTION"
|
|
.B mkeficapsule
|
|
command is used to create an EFI capsule file for use with the U-Boot
|
|
EFI capsule update.
|
|
A capsule file may contain various type of firmware blobs which
|
|
are to be applied to the system and must be placed in the specific
|
|
directory on the UEFI system partition.
|
|
An update will be automatically executed at next reboot.
|
|
|
|
Optionally, a capsule file can be signed with a given private key.
|
|
In this case, the update will be authenticated by verifying the signature
|
|
before applying.
|
|
|
|
.B mkeficapsule
|
|
takes any type of image files, including:
|
|
.TP
|
|
.I raw image
|
|
format is a single binary blob of any type of firmware.
|
|
|
|
.TP
|
|
.I FIT (Flattened Image Tree) image
|
|
format is the same as used in the new uImage format and allows for
|
|
multiple binary blobs in a single capsule file.
|
|
This type of image file can be generated by
|
|
.BR mkimage .
|
|
|
|
.PP
|
|
If you want to use other types than above two, you should explicitly
|
|
specify a guid for the FMP driver.
|
|
|
|
.SH "OPTIONS"
|
|
One of
|
|
.BR --fit ", " --raw " or " --guid

|
option must be specified.

|
|
.TP

|
.BI "-g\fR,\fB --guid " guid-string
|
|
Specify guid for image blob type. The format is:
|
|
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
|
|
|
|
The first three elements are in little endian, while the rest
|
|
is in big endian.
