I have been chewing on this over the past week, and I am starting to think that u-boot is not necessarily the right place for the DDR initialization for this platform. We require ATF in order to load the lpddr4 firmware regardless, so why not do the DDR training and configuration there? This would also abstract out the proprietary memory bits so the code doesn't need to be re-duplicated in the various bootloaders. In theory it should also simplify the MX8 image scripts since SPL would not be a requirement. Thoughts? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
