This is no display on the screen during boot-up when using latest
loongson3_defconfig, because CONFIG_FRAMEBUFFER_CONSOLE=y depends
on CONFIG_FB=y in this file.

Hi Haojun,
It won't work unless you get LS7A dc driver upstreamed or amdgpu firmware resolved.
Thanks.

Hi Jiaxun,
CONFIG_FRAMEBUFFER_CONSOLE is enabled in this config file, but
CONFIG_FRAMEBUFFER_CONSOLE depends on CONFIG_FB and CONFIG_FB is not
selected in this file. This which causes CONFIG_FRAMEBUFFER_CONSOLE to
be unchecked, So it causes these problems.so I selcted CONFIG_FB in
this config file.

Oops, Sorry I get your point now.

This patch has nothing to do with LS7A DC or amdgpu firmware. The
problem is before commit f611b1e7624c ("drm: Avoid circular
dependencies for CONFIG_FB"), FB and FRAMEBUFFER_CONSOLE are selected
by default. But after that it is unselected so we should enable it in
the default config file, otherwise there is no display before Xorg
(even after the GPU driver is loaded, because we have no FB console).
