powerpc: mpc8xx: harmonise initialisation of the immap local pointer
In most places, immap local pointer is defined as immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; In a few places, it is defined as immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); This patch replaces the few of the latest form by the other one. The two are fully equivalent since SPRN_IMMR is set with CONFIG_SYS_IMMR very early in start.S Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr>
