eb77f5c9f6 sunxi: A64: enable SPL
Now that the SPL is ready to be compiled in AArch64 and the DRAM
init code is ready, enable SPL support for the A64 SoC and in the
Pine64 defconfig.
For now we keep the boot0 header in the U-Boot proper, as this allows
to still use boot0 as an SPL replacement without hurting the SPL use
case.
We disable FEL support for now by making its compilation conditional
and disabling it for ARM64, as the code isn't ready yet.

ebc4ef61d7 spl: Add a name to the SPL load-image methods
It is useful to name each method so that we can print out this name when
using the method. Currently this happens using a separate function. In
preparation for unifying this, add a name to each method.

The name is only available if we have libcommon support (i.e can use
printf()).

f28bad13b4 sunxi: Enable SMP mode for the boot CPU on sun9i (A80)
Since the A80 has many cores which we intend to use in SMP fashion,
we should set the SMP bit for the boot CPU.

2a2ee2ac35 spl: Pass spl_image as a parameter to load_image() methods
Rather than having a global variable, pass the spl_image as a parameter.
This avoids BSS use, and makes it clearer what the function is actually
doing.

ecdfd69a4b spl: Convert boot_device into a struct
At present some spl_xxx_load_image() functions take a parameter and some
don't. Of those that do, most take an integer but one takes a string.

Convert this parameter into a struct so that we can pass all functions the
same thing. This will allow us to use a common function signature.

19e99fb4ff sunxi: Support booting from SPI flash
Allwinner devices support SPI flash as one of the possible
bootable media type. The SPI flash chip needs to be connected
to SPI0 pins (port C) to make this work. More information is
available at:

    https://linux-sunxi.org/Bootable_SPI_flash

This patch adds the initial support for booting from SPI flash.
The existing SPI frameworks are not used in order to reduce the
SPL code size. Right now the SPL size grows by ~370 bytes when
CONFIG_SPL_SPI_SUNXI option is enabled.

While there are no popular Allwinner devices with SPI flash at
the moment, testing can be done using a SPI flash module (it
can be bought for ~2$ on ebay) and jumper wires with the boards,
which expose relevant pins on the expansion header. The SPI flash
chips themselves are very cheap (some prices are even listed as
low as 4 cents) and should not cost much if somebody decides to
design a development board with an SPI flash chip soldered on
the PCB.

Another nice feature of the SPI flash is that it can be safely
accessed in a device-independent way (since we know that the
boot ROM is already probing these pins during the boot time).
And if, for example, Olimex boards opted to use SPI flash instead
of EEPROM, then they would have been able to have U-Boot installed
in the SPI flash now and boot the rest of the system from the SATA
hard drive. Hopefully we may see new interesting Allwinner based
development boards in the future, now that the software support
for the SPI flash is in a better shape :-)

Testing can be done by enabling the CONFIG_SPL_SPI_SUNXI option
in a board defconfig, then building U-Boot and finally flashing
the resulting u-boot-sunxi-with-spl.bin binary over USB OTG with
a help of the sunxi-fel tool:

   sunxi-fel spiflash-write 0 u-boot-sunxi-with-spl.bin

The device needs to be switched into FEL (USB recovery) mode first.
The most suitable boards for testing are Orange Pi PC and Pine64.
Because these boards are cheap, have no built-in NAND/eMMC and
expose SPI0 pins on the Raspberry Pi compatible expansion header.
The A13-OLinuXino-Micro board also can be used.

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
The SPL code already knows which boot device it calls the spl_boot_mode()
on, so pass that information into the function. This allows the code of
spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets
board_boot_order() correctly alter the behavior of the boot process.

The later one is important, since in certain cases, it is desired that
spl_boot_device() return value be overriden using board_boot_order().

28d68045cc sunxi: Properly announce BOOT_DEVICE_BOARD as "FEL"

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".

The Allwinner A64 SoC is used in the Pine64. This patch adds
all bits necessary to compile U-Boot for it running in AArch64
mode.

Unfortunately SPL is not ready yet due to legal problems, so
we need to boot using the binary boot0 for now.
