* include/flash.h: Modest API change: cyg_flash_init() no longer takes a printf function argument. Instead two new API functions are available: cyg_flash_set_printf() and cyg_flash_set_global_printf(). * src/flash.c (CHATTER): Don't attempt output if printf function is NULL. (cyg_flash_init): No longer takes printf arg. (cyg_flash_set_printf): New. Set per-device printf function, locking if needed. (cyg_flash_set_global_printf): New. Set printf function for all devices, locking if needed. * src/flashiodev.c (flashiodev_init): cyg_flash_init no longer takes printf arg, and we can leave global printf at default. * src/flashiodevlegacy.c (flashiodev_init): Ditto. * src/legacy_api.c (flash_init): cyg_flash_init no longer takes printf arg. So call cyg_flash_set_global_printf as well. * src/legacy_dev.c (legacy_flash_init): legacy drivers can't handle NULL printf function, so provide a dummy. * doc/flash.sgml: Document removal of printf functionality of cyg_flash_init() and document cyg_flash_set_printf() and cyg_flash_set_global_printf().
