[U-Boot] [mcf532x] dependency of start.S not correct

[U-Boot] [mcf532x] dependency of start.S not correct

[Wolfgang Wegner]

Hi,

sorry I can not provide a solution, but when trying to migrate my
board to newer U-Boot I realised that the dependency calculation
is not correct for cpu/mcf532x/start.S

start.S references several CONFIG_SYS_ macros and thus should be
re-compiled when the board configuration header file changes (like
all the .c files in this directory are), but is not.

I have to admit I do not really understand how dependencies are
calculated in U-Boot build system, so forgive me that this is
merely a bug report than a patch.

Regards,
Wolfgag

Wolfgang,

Have you checked your board/Your_platform/u-boot.lds?

[U-Boot] [mcf532x] dependency of start.S not correct

Hi TsiChung,

basically my u-boot.lds is a copy from m5329evb, minus some things
that I do not need (e.g. env_embedded.o) and some things I do not
really remember why I did them (seperated *(.rodata) and *(.rodata1)).

However, I do not see what the linker script has to do with the
dependencies? All the .c files in the cpu/mcf532x directory get
(correctly) rebuilt when the board configuration header file is
changed, only the start.S has to be touched manually to get
rebuilt.

Anyways, thank you for the hint for checking.
