configs: tinker: Enable SDRAM, SPL stack
SPL sets up SDRAM while in its board_init_f() function, it is possible for the stack to move there before board_init_r() is reached. So it is required to reserve the stack for SDRAM, with a proper location and size otherwise any operations during SPL handoff would leads to failure. On, this particular context tinker-rk3288 SPL is failing to launch U-Boot proper on SDRAM due to lack of stack. U-Boot SPL 2019.10-rc3-00297-g5ba8b12543 (Sep 12 2019 - 08:50:36 +0530) Trying to boot from MMC1 spl: mmc init failed with error: -110 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### So, enable SPL_STACK_R_ADDR and it's related-config items for SDRAM, SPL stack to setup properly.
