Subject: ARM: shmobile: Remove old SCU boot code
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4f6da36f7edd57901638df84d1dcbece28831334;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: shmobile: Remove old SCU boot code

Remove shmobile_secondary_vector_scu now when all SCU enabled
SMP platforms instead make use of shmobile_boot_scu. This
removes two inline virtual to physical address conversions.
