[PATCH v7 08/11] binman: capsule: Add support for generating EFI capsules
Sughosh Ganu
sughosh.ganu at linaro.org
Sat Aug 5 13:34:55 CEST 2023
Add support in binman for generating EFI capsules. The capsule
parameters can be specified through the capsule binman entry. Also add
test cases in binman for testing capsule generation.
Signed-off-by: Sughosh Ganu <sughosh.ganu at linaro.org>
---
Changes since V6:
* Add macros for the GUID strings in sandbox_efi_capsule.h
* Highlight that the private and public keys are mandatory for capsule
signing.
* Add a URL link to the UEFI spec, as used in the rst files.
* Use local vars for private and public keys in BuildSectionData()
* Use local vars for input payload and capsule filenames in
BuildSectionData().
* Drop the ProcessContents() and SetImagePos() as the superclass
functions suffice.
* Use GUID macro names in the capsule test dts files.
* Rename efi_capsule_payload.bin to capsule_input.bin.

+Entry: capsule: Entry for generating EFI Capsule files
+------------------------------------------------------
+
+The parameters needed for generation of the capsules can
+be provided as properties in the entry.
+
+Properties / Entry arguments:
+ - image-index: Unique number for identifying corresponding
+ payload image. Number between 1 and descriptor count, i.e.
+ the total number of firmware images that can be updated.
+ - image-type-id: Image GUID which will be used for identifying the
+ updatable image on the board.
+ - hardware-instance: Optional number for identifying unique
+ hardware instance of a device in the system. Default value of 0
+ for images where value is not to be used.
+ - fw-version: Optional value of image version that can be put on
+ the capsule through the Firmware Management Protocol(FMP) header.
+ - monotonic-count: Count used when signing an image.
+ - private-key: Path to PEM formatted .key private key file. This property
+ is mandatory for generating signed capsules.
+ - public-key-cert: Path to PEM formatted .crt public key certificate
+ file. This property is mandatory for generating signed capsules.
+ - oem-flags - Optional OEM flags to be passed through capsule header.
+
+ Since this is a subclass of Entry_section, all properties of the parent
+ class also apply here.
+
+For more details on the description of the capsule format, and the capsule
+update functionality, refer Section 8.5 and Chapter 23 in the `UEFI
+specification`_.
+
+The capsule parameters like image index and image GUID are passed as
+properties in the entry. The payload to be used in the capsule is to be
+provided as a subnode of the capsule entry.
+
+A typical capsule entry node would then look something like this::
+
+ capsule {
+ type = "efi-capsule";
+ image-index = <0x1>;
+ /* Image GUID for testing capsule update */
+ image-type-id = SANDBOX_UBOOT_IMAGE_GUID;
+ hardware-instance = <0x0>;
+ private-key = "path/to/the/private/key";
+ public-key-cert = "path/to/the/public-key-cert";
+ oem-flags = <0x8000>;
+
+ u-boot {
+ };
+ };
+
+In the above example, the capsule payload is the U-Boot image. The
+capsule entry would read the contents of the payload and put them
+into the capsule. Any external file can also be specified as the
+payload using the blob-ext subnode.
