Are those two incompatible? I would recommend starting without board
specific defconfig
files, it just gets messy once you get more than a few machines you
want to support.

You usually don't want to select 'CONFIG_EMBEDDED' for regular
builds, it's should only be needed to disable options that are
usually considered essential.

You have a framebuffer console here, but no framebuffer driver?

Maybe use EXT4, not EXT2, in the defconfig?

Thanks.
These 2 are incompatible.
They use different drivers. I may still keep these 2 defconfigs.

Thanks.
I will remove this config in the next version patch.

Thanks.
I shall enable it when I push our framebuffer in the next time.
I will disable it in the next version patch.

Thanks.
I will enable EXT4 instead of EXT2 in the defconfig.

Using different drivers doesn't make machines incompatible. For instance, the
x86 desktop machine has drivers for all kinds of devices, but it uses
one configuration
that works on basically any x86 machine.

Similarly, we only have one defconfig file on arm64, and it works across very
diverse machines (phone, home routers, large servers, etc.).

All drivers should be written in a way to allow being built into the
kernel without
doing any harm when you don't have the respective hardware.

The fbdev subsystem is no longer recommended for new drivers, they
should be written on top of the DRM framework. You can use
CONFIG_DRM_FBDEV_EMULATION to get the framebuffer
console on top of that, but then you don't need to enable CONFIG_FB.

Please have a look at drivers/gpu/drm/tinydrm/ to see if you can either
use that directly, or take it as a skeleton for your own driver.

Thanks.
Make sense.
I will keep only one defconfig in the next version patch.

Thanks.
We will check how to use CONFIG_DRM_FBDEV_EMULATION to get framebuffer.
