Commit 6fe50e395080 ("arm: asm/system.h: mrc and mcr need .arm if
__thumb2__ is not set") is not a proper fix for the LTO link error
mentioned in its description. It causes 32-bit arm instructions to be
mixed with thumb instructions, which the Kirkwood SoCs do not support.
For example, board_init_r() is mostly generated in Thumb-1 mode as
expected since the build flags contain -mthumb -mthumb-interwork. The
MCR instruction corresponding to writefr_extra_feature_reg() is also
correcly emitted as a 32-bit ARM instruction (it cannot be encoded in
Thumb-1 anyways). The problem is, the compiler inlines the MCR without
generating the BX or BLX instruction which are needed to transition
between the ARM and the Thumb-1 states. From the objdump output:

                ^^^^^^^^
                32-bit ARM instruction

Further investigation is needed to understand how to fix the issue so
that the code size is minimal for all boards. In the mean time, this
fix disables LTO for the two problematic files (common/board_f.c and
common/board_r.c). This makes the Kirkwood-based boards bootable again.
The binary size is increased by 1048 bytes which is perfectly
acceptable.

As stated in 5e847f7729b3 ("efi_loader: call efi_init_early() earlier"):

    efi_init_early() creates an event hook for block device probing.
    It has to be called before any block device is probed.

Indeed, efi_bl_init() registers EVT_DM_POST_PROBE event, which calls
efi_disk_probe() whenever any block device is probed. And to make that
hook work, the initialization of all block devices was put after
efi_init_early() in initcall_run_r():

    INITCALL(efi_init_early);
    INITCALL(initr_nand);
    INITCALL(initr_onenand);
    INITCALL(initr_mmc);

Because LDFW firmware is being read from MMC, attempt to load LDFW in
board_init() causes MMC driver to be probed. And because board_init() is
executed before efi_init_early(), the hook mentioned above won't work
for MMC devices anymore. So EFI disk objects won't be created, which in
turn makes the EFI subsystem non-functional, showing next symptoms:
  - 'efidebug dh' output is empty
  - attempt to add boot devices in 'eficonfig' shows this message:
    "No block device found!"
  - 'bootefi selftest $fdtcontroladdr' shows this warning:
    "Cannot persist EFI variables without system partition"
  - booting GRUB with 'bootefi' runs minimal GRUB shell which doesn't
    see any block devices as well, probably because EFI vars weren't
    passed

Load LDFW in board_late_init() instead, as it's called after
efi_init_early(). This fixes the described problem and makes it possible
to run EFI apps like GRUB correctly, add entries in 'eficonfig', and
makes 'efivar --list' command in Linux rootfs actually show EFI
variables.

The only user of LDFW at the moment is the TRNG driver, and it's probed
later, only when it's going to be used (e.g. on "rng" command). So it's
fine to load LDFW in board_late_init(). Now the corresponding call order
will look like this:

    efi_init_early()
    initr_mmc()
      mmc_probe()
        EVT_DM_POST_PROBE -> efi_disk_probe()
    board_late_init()
      load_ldfw() -> fs_read(), blk_dread()
    exynos_trng_probe()
