[PATCH v1 4/4] drm/radeon: Implement the is_boot_device callback function
...f we remove the #ifdef and #endif guards.
because the PCI bar will move (resource re-allocation).
[how]
The device that owns the firmware framebuffer should be the default boot
device. This patch adds an arch-independent function to enforce this rule.
The vgaarb subsystem will call back to radeon_is_boot_device() function
when drm/radeon is successfully bound to a radeon GPU device.

[PATCH v1 0/4] PCI/VGA: Improve the default VGA device selection
...vice drivers or video aperture helpers may
have better knowledge about which PCI bar contains the firmware FB,
This patch tries to solve the above problems by introducing a function
callback to the vga_client_register() function interface. DRM device
drivers for the PCI device need to register the is_boot_device() function
callback during the driver loading time. Once the driver binds the device
successfully, VRAARB will call back to the driver. This gives the device
drivers a chance to provide accurate boot device identification. Which in
turn unlock the abitration service to non-x86 architectures. A devi...

[PATCH v2 1/2] vgaarb: various coding style and comments fix
From: Sui Jingfeng <suijingfeng at loongson.cn>
To keep consistent with vga_iostate_to_str() function, the third argument
of vga_str_to_iostate() function should be 'unsigned int *'.
