dafd64888c cmd: replace the cast of the memory access to a fixed bit type in itest
This patch fixes a bug that long word(.l) memory access in 'itest'
command reads the 8bytes of the actual memory on 64-bit architecture.
The cast to the memory pointer should use a fixed bit type.

04681cb3a4 cmd: disk: Fix unused variable warning
If serial support is not compiled into U-Boot, which may be the case
for some SPL builds, the following warning will be generated in disk.c:

cmd/disk.c: In function 'common_diskboot':
cmd/disk.c:16:6: warning: variable 'dev' set but not used [-Wunused-but-set-variable]
  int dev, part;
      ^
The warning is a result of printf() calls being optimized away, and
thus the whole dev variable becomes indeed unused. Mark the variable
as __maybe_unused .

6238935d01 Add a mailbox driver framework/uclass
A mailbox is a hardware mechanism for transferring small message and/or
notifications between the CPU on which U-Boot runs and some other device
such as an auxilliary CPU running firmware or a hardware module.

This patch defines a standard API that connects mailbox clients to mailbox
providers (drivers). Initially, DT is the only supported method for
connecting the two.

The DT binding specification (mailbox.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.

1163625898 Rename reset to sysreset
The current reset API implements a method to reset the entire system.
In the near future, I'd like to introduce code that implements the device
tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.

So fix the endianess conversion to use 64-bit sized operations, for

Also we use a local variable for the image_size to avoid both writing
to the header and also accessing it after we actually unmapped it.

087504958a Revert "sunxi: Reserve ATF memory space on A64"
The ARM Trusted Firmware (ATF) code now lives in SRAM on the Pine64/A64,
so we can claim the whole of DRAM for OS use.

This reverts commit 3ffe39ed2b.

28d68045cc sunxi: Properly announce BOOT_DEVICE_BOARD as "FEL"
This addresses a cosmetic issue when booting a sunxi device
over USB (FEL mode), where the SPL currently would just print
"Trying to boot from ". The patch fixes that to properly read
"Trying to boot from FEL".

b19236fd1c sunxi: Increase SPL header size to 64 bytes to avoid code corruption
The current SPL header, created by the 'mksunxiboot' tool, has size
32 bytes. But the code in the boot ROM stores the information about
the boot media at the offset 0x28 before passing control to the SPL.
For example, when booting from the SD card, the magic number written
by the boot ROM is 0. And when booting from the SPI flash, the magic
number is 3. NAND and eMMC probably have their own special magic
numbers too.

Currently the corrupted byte is a part of one of the instructions in
the reset vectors table:

    b     reset
    ldr   pc, _undefined_instruction
    ldr   pc, _software_interrupt      <- Corruption happens here
    ldr   pc, _prefetch_abort
    ldr   pc, _data_abort
    ldr   pc, _not_used
    ldr   pc, _irq
    ldr   pc, _fiq

In practice this does not cause any visible problems, but it's still
better to fix it. As a bonus, the reported boot media type can be
later used in the 'spl_boot_device' function, but this is out of
the scope of this patch.
