The display core files rely on FPU, which requires to be compiled with special flags. Ideally, we don't want these FPU operations spread around the DC code; nevertheless, it happens in the current source. This commit introduces a new directory inside DML for centralizing shared DCN functions that require FPU and have been used outside DML. For illustrating this process of transferring FPU functions to the DML folder, this commit moves one of the functions dcn20_populate_dml_writeback_from_context) that require FPU access to a single shared file. Notice that this is the first part of the work, and it does not fix the FPU issue yet; we still need other patches for achieving the complete FPU isolation. Changes since V3: - Jun: Instead of creating a new directory to keep the FPU code, let's make the DML folder the only part that requires FPU access. Drop fpu_operation folder. - Christian: Fix function code style. Changes since V2: - Christian: Remove unnecessary wrapper. - lkp: Add missing prototype. - Only compile the FPU operations if the DCN option is enabled. Change since V1: - Update documentation and rebase.
