Q: sp805 watchdog is only for fsl ?

Hello, In watchdog sp805_wdt.c there is usage of gd->bus_clk which seems to be initialized only in fsl code. So, it seems that sp805 usage is limited to fsl chips. I think it could have been generic for any other chip if the clock was initialized using device tree. What do you think? Thanks

For writes, you'll need to do a read-modify-write sequence on the entire block, after you determine what the proper block is given prior block-skipping. Or better, don't try to use this simplistic mechanism to do writes in the middle of a partition -- use something like ubi that was meant for this
