From b2cdef4861befb65e784c01ed71a48bfb811ab38 Mon Sep 17 00:00:00 2001 From: Goldschmidt Simon Date: Fri, 9 Feb 2018 20:23:17 +0000 Subject: env: restore old env_get_char() behaviour With multiple environments, the 'get_char' callback for env drivers does not really make sense any more because it is only supported by two drivers (eeprom and nvram). To restore single character loading for these drivers, override 'env_get_char_spec'.
