[coreboot] ERROR: Ramstage region _postram_cbfs_cache overlapped

[Sid R]

Hello,
While compiling coreboot, I get the following error - any ideas on how to
address this:

Performing operation on 'BOOTBLOCK' region...
W: Written area will abut bottom of target region: any unused space will
keep its current contents
Performing operation on 'COREBOOT' region...

Thanks

This is a recently added warning (see
https://review.coreboot.org/13949) that tells you that you are trying
to use a payload which would overlap the parts of coreboot that are
loading it (risking random corruption errors and such). The fix is to
link your payload to a different base address which does not overlap
the POSTRAM_CBFS_CACHE region in the memlayout.ld of your
board/chipset.

Which board are you building for and which payload are you trying to use?
