powerpc: export MIN RMA size
Commit 683eab94da75bc ("powerpc/fadump: setup additional parameters for
dump capture kernel") introduced the additional parameter feature in
fadump for HASH MMU with the understanding that GRUB does not use the
memory area between 640MB and 768MB for its operation.
However, the third patch ("powerpc: increase MIN RMA size for CAS
negotiation") in this series is changing the MIN RMA size to 768MB,
allowing GRUB to use memory up to 768MB. This makes the fadump
reservation for the additional parameter feature for HASH MMU
unreliable.
To address this, export the MIN_RMA so that the next patch
("powerpc/fadump: fix additional param memory reservation for HASH MMU")
can identify the correct memory range for the additional parameter
feature in fadump for HASH MMU.
