This is a problem for uart boot mode as ROM downloads directly to starting of MSMC RAM. Fixing it by moving stack to the end of u-boot section and shifting SYS_TEXT_BASE to the start of MSMC RAM. Updated division of MSMC RAM is shown below: ----------------------------------------- | | | | | U-Boot text |U-Boot | SPL text | | download | Stack | Download + | | | | SPL_BSS + | | | | SPL_STACK | ----------------------------------------- [1] [2] [3] [4] [1] SYS_TEXT_BASE (Start of MSMC RAM) [2] SPL_TEXT_BASE - GBL_DATA_SIZE [3] SPL_TEXT_BASE [4] END of SPL [1] + [2] is at least 1M on all platforms, so no chance of overlap.
