BaseTools/Capsule: Supports multiple payloads and drivers in capsule

[edk2-devel] [PATCH V2] BaseTools/Capsule: Supports multiple payloads and drivers in capsule

Posted by Eric Jin 4 years, 9 months ago

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1834

1)Add arguments "--embedded-driver" to support embedded driver
in command line.
2)Add arguments "--update-image-index" to identify ImageIndex
within the device in command line.
3)Add arguments "-j JSONFILE" to support multiple payloads and
embedded drivers with JSON file.

The update is in a backwards compatible manner, so all command
line options to support single payload are still supported. But
all the options associated with multiple payloads should be
provided in a JSON file.

Re: [edk2-devel] [PATCH V2] BaseTools/Capsule: Supports multiple payloads and drivers in capsule

Subject: [PATCH V2] BaseTools/Capsule: Supports multiple payloads and drivers in capsule

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1834

1)Add arguments "--embedded-driver" to support embedded driver
in command line.
2)Add arguments "--update-image-index" to identify ImageIndex
within the device in command line.
3)Add arguments "-j JSONFILE" to support multiple payloads and
embedded drivers with JSON file.

The update is in a backwards compatible manner, so all command
line options to support single payload are still supported. But
all the options associated with multiple payloads should be
provided in a JSON file.
