This function calls rtc_write32, which has a different signature depending on if (SPL_)DM_RTC is enabled or not. This could result in a mismatch in SPL if DM_RTC was enabled but SPL_DM_RTC, as the non-DM declaration would still be used in SPL even though the implementation would be for non-DM_RTC. We are switching to the correct definitions in the next commit, so this will become a compilation error. Since fsp_save_s3_stack is not called from SPL, avoid compiling it if (SPL_)DM_RTC is disabled. Signed-off-by: Sean Anderson <sean.anderson@seco.com>
