After some more compiles, I finally figured it out; it's the RAM.
The Hynix HMT151R7BFR4C-H9 sticks I have work fine in Libreboot, but
didn't work with any Coreboot release I tried (tagged 4.6, the last
build reported in board status for the KCMA-D8, and master). Tossed in
the old RAM I had lying around, and Coreboot boots fine even on master.
I wasn't expecting the RAM to be an issue since it worked in Libreboot
though. As I understand, RAM compatiblity varies between the
stock/proprietary BIOS and Libreboot/Coreboot, but I didn't think the
compatibility would also vary between Libreboot and Coreboot.

Hynix HMT151R7BFR4C-H9 RAM sticks. All my attempts of getting
Coreboot to POST with this board so far haven't worked. I'm compiling
Coreboot from Git (master branch), and can build it without issue. A
pre-built Libreboot ROM (20160907) POSTs and boots fine.
For Coreboot's config, I've tried including/excluding CPU microcode
updates, along with some less important-sounding options. For
hardware, I've tried unplugging everything external (KB/mouse), my
GPU (RX 580), and only had a single RAM stick in (slot A1). I've also
tried a single CPU being powered (kept the 2nd CPU in but only had a
single 4-pin CPU going to the 1st CPU).
Can anyone else confirm Git builds of Coreboot booting on this board,
or provide any tips as to anything I could be missing?
I see this issue https://ticket.coreboot.org/issues/151
but there's a
board status months after that that looks like it boots:
