Hi,

I am developing U-Boot for ARM CPU and enabled FLASH support.
During the compilation getting the following error -

arch/arm/lib/libarm.o: In function `board_init_r':
/sites/eqx/work/swdrivers03-1/snagalla/Omsai_STOMP_40G_DEV/Boot/Bootflash/STOMP_40G/u-boot/arch/arm/lib/board.c:922: undefined reference to `flash_init'

When I check the code the respective flash.h is included. But still seeing the error.
Any inputs are highly appreciated...

Thanks & Regards,
