So there are no mmc0 messages from the kernel at all ? Sounds like there is
an issue with the card-detect pin on your sdcard slot (u-boot does not
use this, it assumes the card is there as it is booting from it), you
could tree cleaning the slot a bit, e.g. blow some air through it.
Interesting. I wiggled the card some and blew air in a few places, and some
time during that fedora spit out:
mmc0: host does not support reading read-only switch. assuming write-enable.
Which I see in kashyap's output as well. However that's all I got and I can't
reproduce yet, and not sure specifically what I did during that time.
Would there be mmc0 messages in the kernel output even if no sdcard is
inserted? Or is it dependent on a card being present?

There is no way to make things boot directly from sata, you always need
u-boot somewhere else as the bootrom inside the soc does not support sata.
You could leave a tiny sdcard in the slot with just u-boot though, and run
everything else from sata.
Does /boot need to populated on the sdcard as well? Or can I make uboot on the
sdcard use /boot from my sata drive?
Thanks,
