[PATCH] bloblist: Drop BSD license
Linaro has decided to write their own version of bloblist from scratch, so there is no point in having a non-GPL license on this file. Change it, to better fit with the U-Boot project.

Nit: I'd prefer to word this more neutrally, "TF-A has created a BSD-3 licensed version of bloblist support, so there is no point...".

But, once we get everyone else that touched it since commit 6c9e3d1fc085 ("bloblist: Relicense to allow BSD-3-Clause") I'm fine with it.

Apart from the commit message being wrong, it's also intentionally provoking. There was no bloblist in TF-A.
The TF-A code is implementing the firmware hand-off spec [0], which Linaro participated in the creation. The U-Boot implementation was adjusted to adhere to the same spec after the TF-A code was merged.

The TF-A code is implementing the firmware hand-off spec [0], which Linaro participated in the creation. The U-Boot implementation was adjusted to adhere to the same spec after the TF-A code was merged.
The U-Boot series was [1], for reference. This was mostly about using different tags and shrinking the headers. My clear understanding was that we were going to try to have a single codebase, which is why I changed the license.
So, since you have a different view of events, why did Linaro write it from scratch? Was it to avoid having U-Boot code in TF-A? Or was the author just unaware of the original intention? It isn't relevant for the commit message, but if you can find out I would be interested.

I am not sure I am following 'from scratch'. Firmware handoff is a doc describing a list. Raymond implemented it in U-Boot and TF-A. The right way to do this is to move the firmware handoff code to a library that can be used across projects.

"The non-GPL license was inadvertently added, remove it". Raymond wrote that code so I don't think he minds removing the extra license.

Not always. Probably not in this case. It has quite a bit of logic which depends on its environment. So I think it is better to have 'similar' code in several projects. Certainly, writing it from scratch (meaning not based on existing code) is not the best approach.

Yes, that's why I added the license, since I was led to believe that TF-A would use the U-Boot code with some modifications.

The original bloblist impl was in 2018:
commit 9f407d4ef092c2ce7ab0f4f366aee252611dab3c Author: Simon Glass sjg@chromium.org Date: Thu Nov 15 18:43:50 2018 -0700
Add core support for a bloblist to convey data from SPL
At present there is no standard way in U-Boot to pass information from SPL to U-Boot proper. But sometimes SPL wants to convey information to U-Boot that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM then it might want to pass the size of SDRAM, or the location of each bank, to U-Boot proper.
Add a new 'bloblist' feature which provides this. A bloblist is set up in the first phase of U-Boot that runs (i.e. TPL or SPL). The location of this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else. ...

So the tl;dr is that when the firmware handoff code was added in TF-A, there was no u-boot implementation. It all got added afterwards. The way the development happened is that Raymond implemented the TF-A code, and also plugged in the transfer mechanism so we use that info. The fact that there was a similar implementation in U-Boot, which did not adhere to the standard to begin with doesn't justify your commit message. As I said we didn't decide to write a 'bloblist' we implemented the spec in TF-A.

Er, they are the same thing.
But I am relieved you didn't add a new common/firmware_ho.c into U-Boot

The reason I object to the commit message is because it's *intentionally* misleading. The BSD-3 clause was added by you in 6c9e3d1fc0859 with the intention of other projects using 'bloblist'.
Yes, that's why I added the license, since I was led to believe that TF-A would use the U-Boot code with some modifications.
The actual firmware handoff code was added much later in e266d2731145. All of the patches in that series is co-developped by Raymond. Those were added Wed Dec 27 while the TF-A patches were merged much much earlier. commit 3ba2c15147c in TF-A was merged Tue Jul 25
The original bloblist impl was in 2018:

Add core support for a bloblist to convey data from SPL At present there is no standard way in U-Boot to pass information from SPL to U-Boot proper. But sometimes SPL wants to convey information to U-Boot that U-Boot cannot easily figure out. For example, if SPL sets up SDRAM then it might want to pass the size of SDRAM, or the location of each bank, to U-Boot proper. Add a new 'bloblist' feature which provides this. A bloblist is set up in the first phase of U-Boot that runs (i.e. TPL or SPL). The location of this info may be in SRAM or CAR (x86 cache-as-RAM) or somewhere else. ...So the tl;dr is that when the firmware handoff code was added in TF-A, there was no u-boot implementation. It all got added afterwards.
No, sorry.
The way the development happened is that Raymond implemented the TF-A code, and also plugged in the transfer mechanism so we use that info. The fact that there was a similar implementation in U-Boot, which did not adhere to the standard to begin with doesn't justify your commit message.
No, this is not correct either.
Firmware handoff started as an ARM effort. I influenced the design early on, suggesting that bloblist would be a good fit and it went that way and version 0.8 was the result. Then a work colleague pushed for halving the size of the headers by using smaller fields, so we did that and also renumbered the tags, to get 0.9. Then I did a U-Boot series to update bloblist to suit that[1]. Then Raymond picked it up, took it through several revisions and got it submitted to U-Boot.
After that, we had the OF_BLOBLIST fiasco.
As I said we didn't decide to write a 'bloblist' we implemented the spec in TF-A.
Whatever you say here, the fact is that in TF-A the code was written from scratch, by which I mean not using the existing U-Boot code. That was not my expectation at the time.
