The newly moved flash TCL routines access the internals of the module too much. Fix the layering issues by adding new core NOR flash APIs: <flash/nor/core.h>: - flash_driver_find_by_name() - self-descriptive <flash/nor/imp.h>: - flash_bank_add() - encapsulates adding banks to bank list - flash_bank_list() - encapsulates retreiving bank list This allows the externs in flash/nor/imp.h to be removed, and these mechanisms may now be re-used by other flash module code.
