I'm trying to compile flashrom with a minimum number of drivers.

Disabling CONFIG_INTERNAL fails to compile because flashrom.c unconditionally looks at ich_generation:


cc -MMD -Os -Wall -Wshadow -Werror -I/usr/include/libusb-1.0  -D'USE_BIG_LOCK=1' -D'USE_CROS_EC_LOCK=1' -D'CONFIG_FT2232_SPI=1' -D'HAVE_FT232H=1'  -D'CONFIG_BUSPIRATE_SPI=1' -D'CONFIG_RAIDEN_DEBUG_SPI=1' -D'CONFIG_DEDIPROG=1' -D'CONFIG_LINUX_SPI=1' -D'NEED_LIBUSB1=1' -D'CONFIG_USE_OS_TIMER=0' -D'HAVE_UTSNAME=1' -D'FLASHROM_VERSION="0.9.9  :  : "' -o flashrom.o -c flashrom.c
flashrom.c: In function 'probe_flash':
