[coreboot] Supported Mainboard in coreboot is missing because of using LATE_CBMEM_INIT

[j443i8 at goat.si]

Hello. I got a MSI MS6178 mainboard for coreboot based on the official 
wiki page https://www.coreboot.org/Board:msi/ms6178

I have followed the wiki to build coreboot but the board is missing in 
make menuconfig here: https://www.coreboot.org/Build_HOWTO

Then i find https://review.coreboot.org/c/coreboot/+/23300

Thus i run 'git checkout tags/4.7'

But when trying to build a image i got following error:

Cloning into 'seabios'...
fatal: https://review.coreboot.org/p/seabios.git/info/refs not valid: is 
this a git repository?
Makefile:18: recipe for target 'seabios' failed


Could someone fix the MSI MS6178 mainboard so that it can be used with 
the recent coreboot?

Thanks!
