Hi experts. I am new to u-boot and would like to share some concern. I will use GPIO on a custom board based on LS1043A so for now I’m using the NXP LS1043ARDB. When I enable GPIO in configs/ls1043ardb_defconfig cmd/gpio.c does not compile because of a strange inclusion.
1) My code is based on the u-boot-fsl-qoriq custodian tree but the issue seems to have global scope since the involved piece of code exists in the mainline repository.
2) Enabling GPIO in configs/ls1043ardb_defconfig
CONFIG_DM_GPIO=y CONFIG_LS1043A_GPIO=y CONFIG_CMD_GPIO=y
3) Compilation output
In file included from cmd/gpio.c:13:0: ./arch/arm/include/asm/gpio.h:4:27: fatal error: asm/arch/gpio.h: No such file or directory #include <asm/arch/gpio.h> ^ compilation terminated. make[1]: *** [cmd/gpio.o] Erreur 1 make: *** [cmd] Erreur 2
Using find command on the u-boot root it looks like the file really does not exist.
4) If I disable this file inclusion (#if(0)…#endif) everything seems to work fine and I may access the only GPIO + led of my board I would like to ask if I’m missing something or if this code may be a legacy code.
Thanks in advance. J.W.
