kirkwood now support dt along with platform data, respective boards need to switch into dm for the same.
Added all board mainatiner, using this driver on their relevant boards. So try to switch to DM_SPI(SPI_FLASH) before migration deadline expires.
Hi Jagan,
And what is the deadline exactly ?
See DM_SPI/SPI_FLASH migration details from,
doc/driver-model/MIGRATION.txt
Thanks for letting me know Jagan...
Just to be clear here. The older Marvell platforms Orion and Kirkwood completely lack DM (Driver-Model) and DT (Device-Tree) support in U-Boot. This needs to be added (similar to what I've done to the newer parts beginning with Armada XP / 38x) so that the SPI driver (and others) can be used as DM-enabled driver.
Please see arch/arm/mach-mvebu/ for more details here.
Any work on this is greatly appreciated as I fear that the support for these older SoC's might get dropped completely otherwise soon.
I had a quick try on one of the kirkwood based boards I have. It was pretty easy to bring in the dts files from Linux and get some basic stuff working. I started with i2c since I can still boot without it, I haven't been brave enough to try spi yet.
Hopefully I can spend a bit more time on it over the weekend.
In terms of a long-term plan. I could upstream support for our board, we still include it in the source we distribute as part of our GPL compliance. Since it's a older board that has been fairly stable we're not doing a lot of development on it. My motivation for retaining support for kirkwood is just in case we have some other EOL part that requires us to release a new bootloader. I could do a blind conversion of other in-tree kirkwood boards but my ability to test them would be quite limited.
