Subject: [SPARC]: Encode I/O space into resource flags on sparc32.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95714e12dfb4794ee120f058fdf763e61baaad82;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[SPARC]: Encode I/O space into resource flags on sparc32.

On sparc64 we don't need to do this because the resource
values are large enough to encode the full physical address.
