Cannot compile kernel with INITRAMFS SOURCE option.
Please move this option to a buildroot patch.

First of all if your problem is only related to Buildroot then
there's not much sense in adding linux-snps-arc at lists.infradead.org
which is used for pure Linux kernel discussions.
Then even in case of Buildroot CONFIG_INITRAMFS_SOURCE could be a problem
only if you don't set Buildroot's BR2_TARGET_ROOTFS_INITRAMFS=y, see
how it is done in snps_axs101_defconfig here
https://git.busybox.net/buildroot/tree/configs/snps_axs101_defconfig#n7
What happens if BR2_TARGET_ROOTFS_INITRAMFS=y then existing in kernel's
defconfig CONFIG_INITRAMFS_SOURCE gets overridden with new value, see
https://git.busybox.net/buildroot/tree/linux/linux.mk#n217
Now if you really want to not use built-in kernel initramfs then simplest
thing to do is to run "make linux-menuconfig" from your Buildroot's folder
and disable or set with nothing CONFIG_INITRAMFS_SOURCE.

Hi Alexey,
Probably my e-mail comments before the patch mislead you...
If you download the kernel source and try to compile it, it won't work because of the INITRAMFS pointing to a non-existing directory. (check log below)
That's why that option should be removed from the standard kernel.

Since the axs101 DT cmdline lacks any reference to root device - how does this
unmodified kernel boot anyways w/o changing DT. Does uboot provide the cmdline for
rootfs ?
The reason we've had initramfs for ages (vs. relying on uboot) is because we can't
have uboot based workflow primarily because Alexey / I have 1 AXS MB and we
constantly keep switching between 700 and HS builds.
I think you can use KCONFIG_ALLCONFIG (grep in Documentation) to override the
INITRAMFS !

Indeed if initramfs is not built-in vmlinux/uImage then kernel command-line
must be adjusted to point to real root device.
This could be done in 2 ways:
[1] Manually modify "bootargs" value in arch/arc/boot/dts/axs10{1|3}.dts
[2] In case of U-Boot it's possible to load device tree blob together with uImage
and in that case U-Boot's "bootargs" env variable will override the one in .dtb

Hi guys,
I don't think maintaining that flag this in the kernel is correct... the kernel simply doesn't compile out of the box.
If you grep for CONFIG_INITRAMFS_SOURCE, ARC is the only architecture that uses that kernel flag by default pointing to an external directory.
I don't think this is proper to have it like this by default from the kernel point of view.
