Hello everybody out there,
first off all - thanks to everyone from the u-boot community for this helpful piece of code :)
Could somebody give me a short overview of the plans regarding the u-boot port of the Kirkwood arch (e.g. Sheevaplug board)?
It's my pleasure to reply you :-) Basic Kirkwood Soc Support patches are available on the u-boot-arm.git/next (will be mainlined soon) Sheevaplug board support patches are also submitted those are under review, you can find them here... http://lists.denx.de/pipermail/u-boot/2009-June/054313.html http://lists.denx.de/pipermail/u-boot/2009-June/054314.html http://lists.denx.de/pipermail/u-boot/2009-June/054316.html
Some other board patches are in pipeline
Currently I'm using the u-boot from git.marvell.com which has first board support for sheevaplug. I'm working on a custom hardware design but as a starting point the sheevaplug seems to work well.
Objective for U-boot at git.marvell.com is to maintain a usable copy of u-boot with all accepted/unaccepted patches at one place to support Kirkwood developers, but once all these patches are mainlined, this repository will be removed.
Sadly there is no generic gpio support - at least I couldn't find it. Are there any plans to support a driver for this feature?
BTW: what you want to do at u-boot level with GPIOs? Current Kirkwood drivers and board support does not need any specific GPIO driver, you can access registers directly to read/write GPIOs. But I think if this is a need in future, I will add gpio driver support. You can provide me your requirements too.
I'm willing to contribute some code if someone guides me a bit?
You are most welcomed.... Pls feel free to raise your queries...
Regards.. Prafulla . .
Thanks in advance, Dieter
