Subject: [PATCH 0/8] bootconfig: Update for the recent reports
Date: Thu, 20 Feb 2020 16:26:23 +0900 [thread overview]
Message-ID: <158218358363.6940.18380270211351882136.stgit@devnote2> (raw)
Hello,
Here are some patches to update bootconfig. There are
several implementation changes and syntax fix/updates.
As we discussed in the previous thread, modifies bootconfig.
- [1/8] Make CONFIG_BOOT_CONFIG=n by default
- [2/8] Add magic word for bootconfig
- [8/8] Print array as multiple commands for
legacy command line
With the magic word, we can identify bootconfig without
checksum, also if we find a wrong bootconfig, there is no
reason to suppress the error message anymore.
- [3/8] Remove unneeded error message silencer
- [4/8] Remove unneeded checksum
In addition, I found some issues on bootconfig syntax, so
fix it. (these also include testcase update)
- [5/8] Reject if subkey and value has same parent
- [6/8] Overwrite value on same key by default
- [7/8] Add append value operator ("+=")
To update synchronously, each patch includes code, test
and documentation. If it is better to split (especially
documentation). please let me know.
TODO: support kernel builtin bootconfig. Should we reuse
firmware builtin loader? But it seems we just need a Makefile.
Thank you,
---
