Subject: [MIPS] Ocelot C: Fix mapping of ioport address range.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ad0b365573718a4a83266f98c9a49305c8eaf0b8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[MIPS] Ocelot C: Fix mapping of ioport address range.

 o Fix warnings
 o 768MB worth of I/O ports were insane
 o 64-bit kernels don't need special handling because ioremap does the magic
