Dear all,
in the DTE meetings we have been discussing how we should add signatures
to device-trees.
Due to the way how libfdt adds properties the sanest place to add
metadata is before the memory reservation block. I have tested this with
the U-Boot->GRUB->Linux boot sequence.
See my slides at
https://github.com/xypron/dte/blob/master/DTE%20-%20Adding%20Metadata.pdf
and the test program I used
https://github.com/xypron/dte/blob/master/src/add_metadata_area.c
In the next DTE meetings we could discuss drafting a specification
change for this.
Best regards
Heinrich
All,
Sorry for the late notice but I am canceling the meeting for tomorrow,
Monday May 3. Something came up for me that I must attend to. Also,
Monday is a holiday in the UK. Grant will not be attending and pehaps
others would not as well.
Frank has been working to prepare for the discussion of the next DTB
format so we will start that discussion next time.
Thanks and sorry again,
Bill

Good afternoon,
Linaro and Arm have been standardizing the FW update mechanism for A-class devices.
The intention behind the standardization is to enable generic implementations of the UEFI UpdateCapsule where:
1) the FW store resides in Secure World controlled flash;
2) there is FW bank duplication (A/B model).
Arm published a specification, at Alpha quality, that defines the FW update model and a set of tools catering for 1) and 2) : https://developer.arm.com/-/media/Files/pdf/FWU-PSA-A_DEN0118_1.0ALP3.pdf
Arm welcomes feedback on the specification.
Please direct feedback to either myself or Grant Likely
The FW update work will be discussed at the EBBR biweekly call this Monday (26th April).
Regards,
Jose
