[PATCH 1/4] ARM: shmobile: rcar-gen2: Make rcar_gen2_dma_contiguous static

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

make C=1:

    arch/arm/mach-shmobile/setup-rcar-gen2.c:186:12: warning: symbol 'rcar_gen2_dma_contiguous' was not declared. Should it be static?

Make it static, and move it inside the function to avoid a "defined but
not used" warning if CONFIG_DMA_CMA=n.

[PATCH 4/4] ARM: shmobile: r8a7779: Remove remainings of removed SCU boot setup code

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Commit 0ca2894b5a900709 ("ARM: shmobile: Use shared SCU SMP boot code on
r8a7779") obsoleted the r8a7779-specific SCU boot code, but forgot to
remove the setup of shmobile_boot_fn and shmobile_boot_arg, which is
overwritten by shmobile_smp_scu_prepare_cpus().

Note that shmobile_scu_base wasn't initialized at that point yet anyway.
