Hey folks. Its been a while. Finally got back on the kernel dev train.
This *mostly* seems to work, but I've ran into an issue which may
require some upstream support.
Basic gist, I was attempting to boot a buildroot-built intramfs, was
mostly working, but it would not give me a login prompt no matter how
much I badgered it, so I decided to try a flash boot. That also failed,
and after much banging my head on the desk and annoying people on irc,
we finally came across *why* it was failing, or at least part of it.
The kernel parser could produce the mtdblockN partitions based on the
devicetree, but for whatever reason, when the hisilicon,fmc-spi-nor read
its superblock, instead of the magic 0x73717368 (sqsh), it read back 0x73717360.
At first I thought it was a mistake of mine, as we had tried modifying
the header, and 0x60 is a `, so it could be a hex editing issue, but nope.
Reading the data in u-boot (2010.06, vendor fork, would like to get mainline
running on it at some point) showed the correct magic, so its something
with the controller driver, I guess. CC'ing the people associated with
that as well, hopefully we can get to the bottom of this.
