[U-Boot-Users] [PATCH] Fix USB support issue for MPC8641HPCN board.

[U-Boot-Users] [PATCH] Fix USB support issue for MPC8641HPCN board.

[Zhang Wei]

The configuration file has already enabled USB, but it
missed definition of CFG_OHCI_SWAP_REG_ACCESS, the USB
on MPC8641HPCN can not work because of the wrong USB
register endian.

And add the USB command to U-Boot commands list.

Who will take care of this patch? I think patches to board configs
generally should be taken care of board / architecture, not subsystem
maintainers. That path is less prone of causing conflicts.

Best regards

Correct. This should go through the 86xx repo.

In general, they do what you want, unless you want consistency.

Right.  This patch is mine.

Wolfgang, procedural question for you, though.

I have already applied patches for the new MPC8610HPCD
board port to the -mpc86xx custodian repository's master
branch.  My original notion was to wait until the next
merge window after 1.3.0 to have you pull these three
patches.

However, there are several more bug-fix patches that
need to go through the -mpc86xx repository now too.

How would you like to handle this?  I see a few viable
options:

1) I can just apply bug fixes to -mpc86xx master as well,
    have you pull it, and pick up the new 8610 port anyway.

2) Apply the bug fixes to a different branch in -mpc86xx
    and ask you to pull that specific branch.

3) Just ACK patches on list and have you apply them
    one-at-a-time "by hand" directly,

4) Uh, something else...?

Thanks,
jdl

Yeah, that is one reason I have been advocating a "for Wolfgang" (merge) 
branch and keeping the master branch a clean to track u-boot.git.  Not 
necessarily the best way, but the best way I know how...

On option 4, you could clone your master branch into a "for the next 
merge window" (testing?) branch to preserve your patches, reset --hard 
your master back to match the current u-boot.git revision level, and 
then apply the bug fixes to the master (or a "merge" branch if you think 
this might happen again ;-).

You will probably have to --force pushes back to denx.de and if someone 
has cloned your -86xx repo, this will probably mess him up (not 
irreparably, but still annoying). :-(

With this method, you can keep rebasing your "for the next merge window" 
against your master branch (updated from u-boot.git) to keep it surfing 
ahead of the wave.

---

Wolfgang has (strongly) expressed his preference for pulling from the 
"master" branch, any my advocation of a "merge" branch doesn't work this 
way.

An alternative methodology that I have not tried yet, but seems logical, 
is to have a "sync" branch that the custodian uses to pull u-boot.git 
into and then rebase the "master" branch against it to keep it surfing 
ahead of u-boot.git.  This should work and keep Wolfgang happier at the 
same time.  Note that the "sync" branch does not need to be pushed back 
to the denx.de custodian repository.

clone u-boot.git <--- u-boot.git
   |                      |
   v                      |

   | ------ sync          |

Looks reasonable in ASCII-art.

Sorry, I already took this directly. Hope you don't mind me stepping
on your toes.

Niklaus Wirth has lamented that, whereas Europeans pronounce his name
correctly (Ni-klows Virt), Americans invariably mangle it into (Nick-
les Worth). Which is to say that Europeans  call  him  by  name,  but
Americans call him by value.
