implement 500mA charging in u-boot using wall-outlet charger

[laforge@…]

u-boot should export two USB configuration descriptors that are completely
identical, with one difference: power consumption. The first config descriptor
should indicate 250 units (500mA), whereas the second one should indicate 50
units (100mA).

Please also note that we should remove the 'self powered' flag in both
descriptors, too.

This has now been implemented as part of svn commit 1364. However, this code
needs some more cleanup, namely

• decouple the raw pcf50606 calls from usbtty into some kind of per-machine

abstraction

• make sure this also works with gserial, not only cdc_acm

Also still missing is the timer code, i.e. just heuristically guess that the ac
wall outlet is plugged in (and switch to 500mA) if we get CHGINS but never see a
USB bus reset following it within 30 seconds.

renaming to reflect that this is only about the wall-outlet charger

[mickey@…]

We don't ship a wall-outlet charger. Closing as WONTFIX.

[laforge@…]

we need this for GTA02!

[mickey@…]

Will we ship a charger for GTA02?

[willie_chen@…]

That's not blocker.

[laforge@…]

so what? Bugzilla documents all known bugs, not only blocker bugs. If it's not
a blocker item, then don't give it blocker priority.

As long as this bug is not fixed, it should remain in bugzilla.

Yes, good point Harald.

Reassigning this and the other ones we closed out yesterday to Harald since we
won't do anything on it until the existential crisis of reaching 1.0 is over,
but Harald feels strongly it should not be closed.

Closing it again, works in GTA02 U-Boot, nobody took care about any possible GTA01 issue for 7 months.
