ARM: keystone2: configs: Move SP to end of u-boot section
Currently u-boot stack is defined at the beginning of MSMC RAM.
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.
