The patch looks good, but the commit log is slightly confusing. Apart
from the typo in the title ("increate"), it would be better to say
something like:

"The Foundation model GIC mapping is wrong, as the GICC region should be
8kB instead of 4kB (the model implements the GICv2 architecture). This
defect prevents the driver from switching to EOImode==1."

Or something similar.

Thanks,

M.
