The LinuxLoader application boots Linux in a way that prevents the OS
from accessing UEFI runtime services. Since we have better ways now
of invoking the kernel (via GRUB, or directly via the kernel's UEFI
stub), remove the obsolete LinuxLoader so that people will no longer
mistake it for a suitable reference of how to invoke the OS from UEFI.

- Linux kernel booting: Look at the doc in the Kernel source :
- Documentation/arm64/booting.txt
- The kernel image must be placed at the start of the memory to be used by the
- kernel (2MB aligned) + 0x80000.
-
- The Device tree blob is expected to be under 2MB and be within the first 512MB
- of kernel memory and be 2MB aligned.
-
- A Flattened Device Tree (FDT) used to boot linux needs to be updated before
- the kernel is started. It needs to indicate how secondary cores are brought up
- and where they are waiting before loading Linux. The FDT also needs to hold
- the correct kernel command line and filesystem RAM-disk information.
- At the moment we do not fully support generating this FDT information at
- runtime. A prepared FDT should be provided at boot. FDT is the only supported
- method for booting the AArch64 Linux kernel.
-
- Linux does not use any runtime services at this time, so we can let it
- overwrite UEFI.

-"images containing or not an 'EFI Boot Stub' (see www.kernel.org/doc/\r\n"
-"Documentation/efi-stub.txt for more information).\r\n"

-"This application can be called either from the EFI Shell or during the\r\n"

-"If the application is called from the EFI Shell, the usual alias\r\n"
-"and variable substitutions apply. Moreover, each path can be either\r\n"
-"an EFI Shell file path or a device path in the text form. The application\r\n"
-"first tries to interpret the path as an EFI Shell file path. If the\r\n"
-"interpretation fails then the path is handled as a device path in the\r\n"

-" line 'console=ttyAMA0,115200 earlycon=pl011,0x7ff80000' using the FDT\r\n"
-" 'fdt.dtb' and the RAM boot file system 'ramdisk.img', all files\r\n"

- device path) is stored. The address of
- the buffer is NULL in case of an error or
- if the path to the FDT is not defined.
- Otherwise, the returned address is the
- address of a buffer allocated with a call
- to AllocatePool() that has to be freed by
- the caller.
- @param[out] InitrdPath A pointer to the buffer where the path
- (EFI Shell file path or device path)
- to the RAM root file system is stored.
- The address of the buffer is NULL in case
- of an error or if the path to the RAM root
- file system is not defined. Otherwise, the
- returned address is the address of a
- buffer allocated with a call to
- AllocatePool() that has to be freed by
- the caller.
- @param[out] LinuxCommandLine A pointer to the buffer where the Linux
- kernel command line is stored. The address
- of the buffer is NULL in case of an error
- or if the Linux command line is not
- defined. Otherwise, the returned address
- is the address of a buffer allocated with
- a call to AllocatePool() that has to be
- freed by the caller.
- @param[out] AtagMachineType Value of the ARM Machine Type
-
- @retval EFI_SUCCESS The processing was successfull.
- @retval EFI_ABORTED The initialisation of the Shell Library failed.
- @retval EFI_NOT_FOUND Path to the Linux kernel not found.
- @retval EFI_INVALID_PARAMETER At least one parameter is not valid or there is a
- conflict between two parameters.
- @retval EFI_OUT_OF_RESOURCES A memory allocation failed.
