Well, if something is cross-platform the code is somewhere
cross-platform too, yes?  For example, if anything DDR related makes
sense to stay as CONFIG_SYS_FSL_... it could go in to
drivers/ddr/fsl/Kconfig and be visible in both cases.  Otherwise
<asm/arch/fsl_ddr.h> and SYS_FSL_... (or whatever makes sense, looking
at the am33xx and mx6 cases, there's no SYS_ type prefix on the defines,
just the IP block names) for the defines.
