Good afternoon,

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) :

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 (26^th April).

Thank you for sharing this document.

Looking at the license this is a generic API definition that is not
bound to TF-A but might also be implemented on non-TF-A and non-ARM
platforms. - Do I get this right?

 From the view of non-secure firmware like U-Boot or EDK II having a
cross-platform specification is preferable.


Correct. The Arm non-confidential document is not restricted to
Arm-based designs.

FW update on A-class Arm devices

[Jose Marinho]

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
