bsps/amd64: add a new EFI-based variant of AMD64 BSP
The new amd64efi BSP supports: - multiboot2 boot format. Runs well with GRUB. - console based on either EFI simple text output or GOP-based framebuffer - clock based on EFI event/timer API - early console using either hard-wired PC-AT serial or just memory buffer - with EFI support disabled the BSP is more or less equivalent to amd64 BSP with multiboot2 support

Select preferred EFI console. Possible values are TEXT, GRAPHIC, BOTH and AUTO. The TEXT here will instruct RTEMS to use EFI simple text output protocol. By default

EFI also forwards such text output to configured serial port. Details depends on the target platform EFI configuration.
|
||||
The GRAPHIC instructs RTEMS to use EFI graphics output protocol. Advantage of it
|
||||
in comparison with TEXT is that it is available also in the time when boot services
|
||||
are already finished. BOTH tells RTEMS to mirror its output to both TEXT and GRAPHIC. This only
|
||||
applies to platforms where both options are supported. The option which is not supported
|
||||
on target platform is ignored in the RTEMS runtime and only available option is used. Finally AUTO tells RTEMS to use output console
|
||||
preferred by the target platform configuration. In case RTEMS is not able to retrieve EFI console control protocol interface, then BOTH
|
||||
is used instead of AUTO.

Set the value of max-page-size parameter for the GNU linker.
|
||||
By default on x86_64 the linker is using 2MB page size which is
|
||||
too big for creating correctly formed and later recognized multiboot2
|
||||
binaries. Default value 4k used here is working well for the purpose.
