e7dcf5645f env: Drop environment.h header file where not needed
This header file is now only used by files that access internal

957f51e863 elf: fix cache flushing in 'bootelf -p' command
Currently there are two problems in 'bootelf -p' (load elf by segments)
command:
- bss section is not flushed, so booted elf can have non zero values
  in bss;
- at least on ARM there are 'CACHE: Misaligned operation at
  range...' warnings

Use p_memsz instead of p_filesz during cache flushing for elf segment.
p_filesz doesn't include zero initialized memory (e.g. bss section),
which also should be flushed.

Align these cache flushes to line boundaries.

Prevent cache warning messages when using the 'bootelf' command on an
Arm target. Round down each section start address and round up the
respective section end to the nearest cache line.

Currently when using bootelf to load an image on Arm, several warnings
such as the following appear in the console:

2846ea81a0 elf: Add support for PPC64 ELF V1 ABI in bootelf
This update adds PPC64 ELF V1 ABI support to bootelf for both the
program header and section header options. Elf64 support was already
present for the program header option, but it was not handling the
PPC64 ELF V1 ABI case. For the PPC64 ELF V1 ABI, the e_entry field of
the elf header must be treated as function descriptor pointer instead
of a function address. The first doubleword of the function descriptor
is the function's entry address.

447ae4f7ad bootvx: x86: Make VxWorks EFI console driver happy
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.

1351700cf2 bootvx: x86: Explicitly clear the bootloader image size
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.

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'.

3194daa10b vxworks: fixed cpu enable using PSCI on armv8
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.

9925f1dbc3 net: Move enetaddr env access code to env config instead of net config
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 f411b5cca4 ("board: am335x: Always set eth/eth1addr environment

when Ethernet is required in Linux, but not U-Boot.
