Add configuration files/dtses for mini u-boot configuration which runs on smaller footprint of internal memory. This configuration has only required qspi flash support and it uses DCC as serial.
Signed-off-by: Siva Durga Prasad Paladugu siva.durga.paladugu@xilinx.com
Chnages for v2:
- Fixed copyright year
- Fixed memory node
- Removed partitions in flash node
- Moved CONFIG_MP to kconfig
