* add temporary test shell-spript * Use LINK_TIME_OPTIMIZATION_ENABLE instead of Link_Time_Optimization No change in build result. * Helix config.h use '#pragma once' No change in build result. * Helix helix.h,rev?/rev?.h,pico/pico.h use '#pragma once' No change in build result. * Use drivers/avr/pro_micro.h instead of keyboards/helix/pro_micro.h No change in build result. * remove keyboards/helix/{rev2|pico}/serial_config.h No change in build result. * 'HELIX_ROWS' macro is now referenced only in rev1/config.h and rev2/config.h. No change in build result. * The contents of helix/rules.mk were distributed to subdirectories. This is a preparation to create a new subdirectory for helix code using split_common. No change in build result. remove 'USE_I2C = yes', 'SUBPROJECT_rev1 = no' from keyboards/helix/rules.mk. follow code move from keyboards/helix/rules.mk to keyboards/helix/{rev1,rev2,pico}/rules.mk. ---- SRC += i2c.c SRC += serial.c SRC += ssd1306.c CUSTOM_MATRIX = yes --- * helix/{i2c.[ch], serial.[ch], ssd1306.[ch]} move into helix/local_drivers/ No change in build result. * Simplified 'helix/pico/keymap/*/rules.mk' using KEYBOARD_LOCAL_FEATURES_MK. No change in build result. * add keyboards/helix/pico/local_features.mk * add 'KEYBOARD_LOCAL_FEATURES_MK := $(dir $(lastword $(MAKEFILE_LIST)))local_features.mk' into keyboards/helix/pico/rules.mk * remove HELIX_CUSTOMISE_MSG from keyboards/helix/pico/keymaps/*/rules.mk * remove HELIX= process from keyboards/helix/pico/keymaps/*/rules.mk * remove convert code(helix to standaerd) from keyboards/helix/pico/keymaps/*/rules.mk * add 'include $(strip $(KEYBOARD_LOCAL_FEATURES_MK))' into keyboards/helix/pico/keymaps/*/rules.mk * Simplified 'helix/rev2/keymap/*/rules.mk' using KEYBOARD_LOCAL_FEATURES_MK. No change in build result. * add keyboards/helix/rev2/local_features.mk * add 'KEYBOARD_LOCAL_FEATURES_MK := $(dir $(lastword $(MAKEFILE_LIST)))local_features.mk' into keyboards/helix/rev2/rules.mk * remove HELIX_CUSTOMISE_MSG from keyboards/helix/rev2/keymaps/*/rules.mk * remove HELIX= process from keyboards/helix/rev2/keymaps/*/rules.mk * remove convert code(helix to standaerd) from keyboards/helix/rev2/keymaps/*/rules.mk * add 'include $(strip $(KEYBOARD_LOCAL_FEATURES_MK))' into keyboards/helix/rev2/keymaps/*/rules.mk * Added helix keyboard build NEW method.
