On VxWorks x86 its bootline address is at a pre-defined offset @
0x1200. If 'bootaddr' is not passed via environment variable, we
assign its value based on the kernel memory base address.

Exit the 'bootvx' command if bootline address is not specified.

There is a small duplication in do_bootvx() that does the bootline
copy. Refactor this a little bit to make it simpler.

When booting from EFI BIOS, VxWorks bootloader stores the EFI GOP
framebuffer info at a pre-defined offset @ 0x6100. When VxWorks
kernel boots up, its EFI console driver tries to find such a block
and if the signature matches, the framebuffer information will be
used to initialize the driver.
However it is not necessary to prepare an EFI environment for
VxWorks's EFI console driver to function (eg: EFI loader in
U-Boot). If U-Boot has already initialized the graphics card and
set it to a VESA mode that is compatible with EFI GOP, we can
simply prepare such a block for VxWorks.

This adds a very simple ELF64 loader via program headers, similar
to load_elf_image_phdr() that we already have.

VxWorks bootloader stores its size at a pre-defined offset @ 0x5004.
Later when VxWorks kernel boots up and system memory information is
retrieved from the E820 table, the bootloader size will be subtracted
from the total system memory size to calculate the size of available
memory for the OS.
Explicitly clear the bootloader image size otherwise if memory
at this offset happens to contain some garbage data, the final
available memory size for the kernel is insane.

address
At present two environment variables 'e820data'/'e820info' are required
to boot a VxWorks x86 kernel, but this is superfluous. The offset of
these two tables are actually at a fixed offset from the kernel memory
base address and we can provide the kernel memory base address to U-Boot
via only one variable 'vx_phys_mem_base'.
Note as it name indicates, the physical address should be provided.

Without armv8_setup_psci register VBAR_EL3 is not set up property which
makes SMC calls jump to invalid location.
smp_kick_all_cpus is required to make slave cpus leave gic_wait_for_interrupt.
Without this they will never pursue booting process.
Fix was applied to the two ways of booting VxWorks: bootvx and bootm commands.
This implementation is very similar to what is done in boot_jump_linux
in arch/arm/lib/bootm.c file.
Tested on VxWorks 7 release SR0520 2017-12-08 Intel Stratix 10 SX SoC
Development Kit board.

In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.
This fixes failures such as:
board/ti/am335x/built-in.o: In function `board_late_init':
board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'
which caters for use cases such as:
commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment
variable")
when Ethernet is required in Linux, but not U-Boot.
