[U-Boot] [PATCH] cmd: fdt: Use separate CMD_FDT Kconfig entry instead of OF_LIBFDT
Create CMD_FDT Kconfig entry to have an option to disable fdt command which is not required for small configuration which requires libfdt only. Enable it by default for all targets which enables OF_LIBFDT.

I think Masahiro knows most about this. If it works it's fine with me. The way you have it is more intuitive and I prefer it. But he did point at a problem at some point.
One other question - won't this disable the 'fdt' command for many boards?

I think "depends on OF_LIBFDT" is correct in this case.
do_fdt() calls fdt_fixup_memory(), which is defined in common/fdt_support.c, which is enabled by CONFIG_OF_LIBFDT.
So, CMD_FDT should depend on OF_LIBFDT. Otherwise, "make menuconfig" would allow users to enable CMD_FDT without OF_LIBFDT, which would cause link error.
One other question - won't this disable the 'fdt' command for many boards?
config CMD_FDT bool "Flattened Device Tree utility commands" default y depends on OF_LIBFDT
"default y" cares about it. So, if CONFIG_OF_LIBFDT is enabled in the defconfig, CONFIG_CMD_FDT should be enabled as well.
But the following 6 boards opt out of Kconfig. They define CONFIG_OF_LIBFDT in their config headers, so this patch would disable "fdt" command for them.

Could you move them to defconfigs?

hm. I wanted to use buildman to show me that but that looks weird. It looks like that it is not running make legoev3_defconfig after new patch because LIBFDT is not enabled when 3 commits are built. But when 2 commits are built then it is enabled properly. Isn't there any bug in buildman?

You may need the -C flag to make it reconfigure on each commit, and now you might need -f also since you already have a build.

I think Masahiro knows most about this. If it works it's fine with me. The way you have it is more intuitive and I prefer it. But he did point at a problem at some point.
I think "depends on OF_LIBFDT" is correct in this case.
do_fdt() calls fdt_fixup_memory(), which is defined in common/fdt_support.c, which is enabled by CONFIG_OF_LIBFDT.
So, CMD_FDT should depend on OF_LIBFDT. Otherwise, "make menuconfig" would allow users to enable CMD_FDT without OF_LIBFDT, which would cause link error.
One other question - won't this disable the 'fdt' command for many boards?
config CMD_FDT bool "Flattened Device Tree utility commands" default y depends on OF_LIBFDT
"default y" cares about it. So, if CONFIG_OF_LIBFDT is enabled in the defconfig, CONFIG_CMD_FDT should be enabled as well.
But the following 6 boards opt out of Kconfig. They define CONFIG_OF_LIBFDT in their config headers, so this patch would disable "fdt" command for them.
include/configs/legoev3.h include/configs/ma5d4evk.h include/configs/pic32mzdask.h include/configs/stm32f746-disco.h include/configs/xilinx-ppc.h include/configs/zipitz2.h
Could you move them to defconfigs?
I have sent v2 to address these. I have used buildman and there is up to 2k difference when symbol is in Kconfig. Not sure why but it shouldn't be big deal.
What does 2k difference mean?
hm. I wanted to use buildman to show me that but that looks weird. It looks like that it is not running make legoev3_defconfig after new patch because LIBFDT is not enabled when 3 commits are built. But when 2 commits are built then it is enabled properly. Isn't there any bug in buildman?

Ah. Ok.
This is causing that 2k diff. #define IMAGE_ENABLE_OF_LIBFDT CONFIG_IS_ENABLED(OF_LIBFDT)
I will run it over all boards which are affected.

I know that you have converted others. I have checked and others boards are just the same (except xilinx_ppc which is not affected) +2k because of that macro. But is this a problem? I mean my goal is to separate CMD_FDT command because it is just too huge if you have just small amount of memory. I don't know these boards but only Xilinx PPC guy has responded that it is fine and none else. It means that they are fine with this change and they can fix it if +2k is problem for them.
I fully understand that this is the problem from conversion point of view if simple move is causing it but at the end of the day I don't think it is worth to invest time to look these 5.
What do you think?

What does 2k difference mean?
hm. I wanted to use buildman to show me that but that looks weird. It looks like that it is not running make legoev3_defconfig after new patch because LIBFDT is not enabled when 3 commits are built. But when 2 commits are built then it is enabled properly. Isn't there any bug in buildman?
Thanks, Michal

You may need the -C flag to make it reconfigure on each commit, and now you might need -f also since you already have a build.
Ah. Ok.
This is causing that 2k diff. #define IMAGE_ENABLE_OF_LIBFDT CONFIG_IS_ENABLED(OF_LIBFDT)
I will run it over all boards which are affected.
Thanks, Michal

That seems bad. I've been in this code quite a bit - it is tricky to keep the options the same - e.g. my recent conversion of CONFIG_FIT to Kconfig was a bit of a mission. Worth digging into...
I know that you have converted others. I have checked and others boards are just the same (except xilinx_ppc which is not affected) +2k because of that macro. But is this a problem? I mean my goal is to separate CMD_FDT command because it is just too huge if you have just small amount of memory. I don't know these boards but only Xilinx PPC guy has responded that it is fine and none else. It means that they are fine with this change and they can fix it if +2k is problem for them.
I fully understand that this is the problem from conversion point of view if simple move is causing it but at the end of the day I don't think it is worth to invest time to look these 5.
What do you think?
Looks OK to me.
