From f055268e3946555deb9bb80b2c8c9798c64dbc47 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Mon, 5 Sep 2022 13:10:24 +0200 Subject: riscv: drop some idefs from CMO initialization Wrapping things in #ifdefs makes the code harder to read while we also have IS_ENABLED() macros to do this in regular code and the extension detection is not _that_ runtime critical. So define a stub for riscv_noncoherent_supported() in the non-CONFIG_RISCV_DMA_NONCOHERENT case and move the code to us IS_ENABLED.
