My view is that smaller patches are easier to review and we should try to break up the patches to logical chucks where possible. I haven't taken a look at the patches myself but I am sure there will be ways to break it up for ease of review.

Fair enough. I have no doubt it was tested. It is just extremely difficult to review such patches and I disagree with your statement. There is almost always a way to split patches up by using feature flags for example, that will help with not breaking the build. You can test them all together once you have all the patches. I also think it is perfectly reasonable to say measured boot cannot be turned on until a certain commit id present. However, if you think this is the right approach, i have no issues.

Thanks Raghu

Hi Raghu and Varun,

This patch is a complete, tested and verified reference implementation for FVP platform. Splitting it will create a set of separate non-buildable patches causing more complexity in following and understanding the code changes and dependencies. The whole patch with all the code present in it should be reviewed anyway, and the time spent will be less than the time used for reviewing separate patches (mass defect).

I second Varun on this. The patch is huge. I recommend breaking it up into multiple commits. I've reviewed it but since it is a large patch, it might require a few more sittings to grasp all the changes(which also means there may be some stupid review comments :)).

Hello Alexei,

Just curious, the patch is huge and will take some time to review. Do you expect this change to be merged before the v2.3 release?
