Subject[PATCH AUTOSEL for 4.9 121/190] net: ethernet: ucc_geth: fix MEM_PART_MURAM mode
Date
From: Christophe Leroy <christophe.leroy@c-s.fr>

[ Upstream commit 8b8642af15ed14b9a7a34d3401afbcc274533e13 ]

Since commit 5093bb965a163 ("powerpc/QE: switch to the cpm_muram
implementation"), muram area is not part of immrbar mapping anymore
so immrbar_virt_to_phys() is not usable anymore.

Fixes: 5093bb965a163 ("powerpc/QE: switch to the cpm_muram implementation")
