The following patches were already sent to the Arago project, but not yet to u-boot ML to be merged into the mainline. They add support for the SPI flash. Compared to the original patches, they are only rebased on the current u-boot tree.

Applies cleanly to 0c0892be0d93a5a892b93739c5eb3bf692fed4ff of git://git.denx.de/u-boot.git; no checkpatch warnings.

Tested along with "[PATCH 2/2] da850: Enable SPI Flash" on da850evm with no changes to the config. SPI flash was usable as the environment and location of the u-boot image.

Hi Stefano,

...

The patch was already posted to the arago project, but not yet to mainline. It allows to save environment into the spi flash. Tested on LogiPD tmdxl138.

If this patch is only "transferred" by you, then please do not change the commit message so that (ideally) one can trace a commit through trees using the messages. Add such additional (transient) information below the "--" in the mail so it will not get into the repository.

Thanks! Detlev

Agree, this is the case of the first patch in the patchset. However, this patch has some slight changes and it will be erroneous to think that it is exactly the same. I think the best solution is to add the original commit message to mine, and grepping for the original message will still work. I'll do in V2.

Best regards, Stefano Babic

Thanks, Stefano.

This version is still good for me.
