From: Sujeet Baranwal <sbaranwal at marvell.com>

commit 258be123226f8f5cd516b7813fe201fb7d7416e9 upstream.

At this moment, only page 0 of SPD is being read but to support
smbios, we need to read page 1 also which has more info. In order
to do that, we need to allocate more space.

Stefan, last time I overlooked this commit. This is also part of
upstream mv-ddr-marvell.
