Subject[PATCH RESEND 0/8] x86 platform framebuffers

I cut down my previous series to no longer include the SimpleDRM driver. If
anyone is interested, you can find it here:
I will resend it once these preparation patches are in.

Changes since v2:
- added common x86 formats (reported by hpa) (patch #5)

This whole series (including simpledrm) is tested by Stephen and me. I would be
glad if maintainers could ack/nack this so I can continue my work.

This series is pretty small and just converts x86 to use platform-devices
instead of global objects to pass framebuffer data to drivers. The commit
messages explain everything in detail.
The idea is to create a "platform-framebuffer" device which drivers can bind to.
If x86 boot code detectes efi or vesa framebuffers, it creates efi-framebuffer
or vesa-framebuffer devices instead.

Additionally, if the modes are compatible, "simple-framebuffer" devices are
created so simplefb can be used on x86. This feature is only enabled if
CONFIG_X86_SYSFB is selected (off by default) so users without simplefb still
get boot logs.

@Stephen: I wasn't sure whether you tested the efi/vesa framebuffer changes,
too, so I didn't add your tested-by there. And I changed patch #5 so I dropped
it there, too. Thanks for testing!


David Herrmann (8):
fbdev: simplefb: add init through platform_data
fbdev: simplefb: mark as fw and allocate apertures
x86: provide platform-devices for boot-framebuffers
x86: sysfb: move EFI quirks from efifb to sysfb
fbdev: simplefb: add common x86 RGB formats
fbdev: vesafb: bind to platform-framebuffer device
fbdev: efifb: bind to efi-framebuffer
fbdev: fbcon: select VT_HW_CONSOLE_BINDING
