2021-07-21	drivers/firmware: consolidate EFI framebuffer setup for all arches	Javier Martinez Canillas	1	-13/+13
	The register_gop_device() function registers an "efi-framebuffer" platform device to match against the efifb driver, to have an early framebuffer for EFI platforms. But there is already support to do exactly the same by the Generic System Framebuffers (sysfb) driver. This used to be only for X86 but it has been moved to drivers/firmware and could be reused by other architectures. Also, besides supporting registering an "efi-framebuffer", this driver can register a "simple-framebuffer" allowing to use the siple{fb,drm} drivers on non-X86 EFI platforms. For example, on aarch64 these drivers can only be used with DT and doesn't have code to register a "simple-frambuffer" platform device when booting with EFI. For these reasons, let's remove the register_gop_device() duplicated code and instead move the platform specific logic that's there to sysfb driver.

2021-07-21	drivers/firmware: move x86 Generic System Framebuffers support	Javier Martinez Canillas	1	-0/+94
	The x86 architecture has generic support to register a system framebuffer platform device. It either registers a "simple-framebuffer" if the config option CONFIG_X86_SYSFB is enabled, or a legacy VGA/VBE/EFI FB device. But the code is generic enough to be reused by other architectures and can be moved out of the arch/x86 directory. This will allow to also support the simple{fb,drm} drivers on non-x86 EFI platforms, such as aarch64 where these drivers are only supported with DT.
