Hello! I'm trying to find if my hardware supports Coreboot. I found 1 table which is retired, second that is probably not retired and then current documentation that doesn't seem to say as much. So, sorry if I missed it. Will Coreboot work with HP ProLiant DL360e Gen8? Flashrom worked ok but not great. Northbridge is Intel Sandy Bridge-E 07, Southbridge Intel X79 05.

Short answer: Nope.
Long answer: Porting this board would be extremely time-consuming (several years for an experienced developer working exclusively on it), because there's no support at all for the chipset. While there's support for mundane Sandy (and Ivy) Bridge consumer (desktop, mobile, uniprocessor server) hardware, the SA and PCH (System Agent and Platform Controller Hub, i.e. integrated northbridge and southbridge respectively) on server platforms are radically different beasts. Memory initialization is by far the most complex thing that would need to be implemented, and the registers aren't publicly documented and differ across generations, as well as between consumer and server platforms.

This is expected for this kind of platform, since the IFD (Intel Flash Descriptor) specifies the regions of the flash chip and their access permissions.
