Hello,
I came across this commit on the github repo titled: "fdtdec: allow board to
provide fdt for CONFIG_OF_SEPARATE" dated 10th Jan in lib/fdtdec.c
The commit changes the following lines:
>elif defined CONFIG_OF_SEPARATE
> ifdef CONFIG_SPL_BUILD
> if (IS_ENABLED(CONFIG_SPL_SEPARATE_BSS))
> gd->fdt_blob = (ulong *)&_image_binary_end;
> else
> gd->fdt_blob = (ulong *)&__bss_end;
> else
> gd->fdt_blob = (ulong *)&_end;
>endif
>elif defined(CONFIG_OF_BOARD)
> gd->fdt_blob = board_fdt_blob_setup();
to
>elif defined(CONFIG_OF_BOARD) || defined(CONFIG_OF_SEPARATE)
> gd->fdt_blob = board_fdt_blob_setup();
where
>if defined(CONFIG_OF_BOARD) || defined(CONFIG_OF_SEPARATE)
>
>__weak void *board_fdt_blob_setup(void)
>{
> void *fdt_blob = NULL;
>ifdef CONFIG_SPL_BUILD
> if (IS_ENABLED(CONFIG_SPL_SEPARATE_BSS))
> fdt_blob = (ulong *)&_image_binary_end;
> else
> fdt_blob = (ulong *)&__bss_end;
>else
> fdt_blob = (ulong *)&_end;
>endif
> return fdt_blob;
>}
>endif
From what i understand, this means that the definition of CONFIG_OF_BOARD and
CONFIG_OF_SEPARATE would have the same behaviour.
Is this the intended outcome?
As I am working on a rpi, the defined board_fdt_blob_setup in
board/raspberrypi/rpi/rpi.c would run instead of the weakly defined
board_fdt_blob_setup from above.
If i wish to have the ability for CONFIG_OF_BOARD and CONFIG_OF_SEPARATE to
have the previous behaviour of board_fdt_blob_setup, should i revert the
fdtdec.c or make the edits under rpi.c?
Many thanks in advance
Warmest Regards,
John Chan
