From efb5dab7ba8a9a6f89e44c4e60b0adb768c77e84 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sat, 21 Aug 2021 13:50:17 -0400 Subject: nxp: Migrate CONFIG_DDR_CLK_FREQ to Kconfig As this symbol can either be a fixed value or the function get_board_ddr_clk, migration is tricky. Introduce a choice of DYNAMIC or STATIC_DDR_CLK_FREQ. If DYNAMIC, we continue to use the board defined get_board_ddr_clk function. If STATIC, set CONFIG_DDR_CLK_FREQ to that value and now include/clock_legacy.h contains the function prototype or defines get_board_ddr_clk() to that static value. Update callers to test for DYNAMIC or STATIC.
