f5ac5ac12d
Add support for QSPI on NXP layerscape LS1012A-RDB, LS1012A-QDS, LS1012A-FRDM and LS1012A-FRWY boards. LS1012A-RDB has 2 Spansion "s25fs512s" flashes of size 64M each and only one can be accessed at a time. LS1012A-QDS/FRDM has 1 spansion "s25fs512s" flash of size 64M. LS1012A-FRWY has one winbond "w25q16dw" flash of size 2M. Use generic compatibles as "jedec,spi-nor" for automatic detection of flash. Configure RX and TX buswidth values as 2 as only two I/O lines are available for data transfer. Add ls1012a(si) node alongwith flash nodes.
