[meta-raspberrypi][PATCH 0/1] linux-rpi: clean .config in before do_configure step

[meta-raspberrypi][PATCH 0/1] linux-rpi: clean .config in before do_configure step

[Piotr Lewicki]

Previously using bbappend files for linux-raspberrypi recipe did not allow to
use "kernel_configure_variable" function to set kernel config variables.
If user wanted to use it in his bbappend with "do_configure_prepend" it was
cleared afterwards. This patch moves cleaning to a separate step.
I'm unsure about whether CONF_SED_SCRIPT variable gets cleaned here. Please
verify this.

we should investigate the kernel tooling from OE-Core and use that IMO

You mean configuration fragments?
I don't like the special kernel cfg stuff for meta-raspberrypi and applied this patch to use the same system with all bsp layers:

I'm all for this. We should get rid of this and unify with oe-core
tooling.

@Piotr Would you like to work on this and remove completely this while
reworking on the kernel fragments configuration support? I'll take a
look on the old patches too.

That would be very helpful. This one of my top things to change in this

I'm wondering if this make sense to rewrite linux-rpi.inc file so that 
it uses config fragments.
If we only apply the old patch from Alex J Lennon ("linux-raspberrypi: 
support configuration fragments / in-tree defconfig") than kernel config 
fragments (using .cfg files with kernel configs) can be used with 
linux-raspberrypi (tested).

All of the kernel configs that are set in "linux-rpi.inc" file (e.g. VC4 
related config flags if one has VC4 support) should be applied even if 
somebody sets some other value in config fragment file.

If we only use Alex's patch then we first apply all of the config 
fragments and then if needed - overwrite them with options necessary by 
the rpi machine.

I'm resending Alex's patch either way for easier applying.

[meta-raspberrypi][PATCH 1/1] linux-rpi: clean .config in before do_configure step

[Piotr Lewicki]

Previously using bbappend files for linux-raspberrypi recipe did not allow to
use "kernel_configure_variable" function to set kernel config variables.
If user wanted to use it in his bbappend with "do_configure_prepend" it was
cleared afterwards. This patch moves cleaning to a separate step.
I'm unsure about whether CONF_SED_SCRIPT variable gets cleaned here. Please
verify this.
