Hi Prafulla,
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
thanks very much for your help. So far I have seen that marvell git u-boot is used to push it to mainline. Great job! What patches are in the 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 working on a custom hardware using the sheevaplug as a starting point. Hopefully end of summer I finish the hardware work and have my own board. But I have some additional requirements. For example control some power supplies for LCD, boot an FPGA, program a clock chip device and so on. So my demands are: - GPIO support (for programming the clock generator which has a simple serial interface to clock in the configuration data) Yeah, I know that I can setup the GPIOs by writing directly to the registers, but a gpio frameworks would be much nicer ;)
- SPI (from the TDM module) support which works independet from NAND flash and SD-Card
I have allready posted a query to arm-linux kernel mailing list and yesterday evening I have talked with Lennert on IRC regarding SPI and linux .
The SPI interface is needed in u-boot to boot my lattice FPGA which is configured as slave serial device (and later on in linux to drive a touch controller). There is allready a FPGA configuration framework inside u-boot and I would like to integrate also a lattice FPGA into that. But to do this I need SPI support.
I'm willing to contribute some code if someone guides me a bit?
You are most welcomed.... Pls feel free to raise your queries...
Here they are :) Thanks, Dieter
