Kinetis flash driver services huge number of MCU types. They have one, two or four flash banks with option of FlexNVM. It would require ~36 config files just for Kx series, more for KLx, KVx and KE1x. The change implements alternative approach: - configuration file creates just one pflash bank (common for all devices) - when a device is probed, additional pflash or flexnvm banks are created based on flash layout of the connected MCU - created banks have names with optional numbering e.g. kx.pflash0 kx.pflash1 kx.flexnvm0 kx.flexnvm1 - the first bank gets renamed if numbering is used Automatic bank creation is enabled by tcl command 'kinetis create_banks'. Used solution has a drawback: other banks than pflash0 are not accessible until pflash0 is probed. Fortunately gdb attach and standard programming accesses banks in right sequence.
