By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.
Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.

There is no need for this to be in the BSS region. By moving it we can delay
use of BSS in SPL. This is useful for machines where the BSS region is not
in writeable space. On 64-bit x86, SPL runs from SPI flash and it is easier
to eliminate BSS use than link SPL to run with BSS at a particular
cache-as-RAM (CAR) address.

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

All the other SPL loaders are in this directory, so move the SPI one in

There are two board-specific SPI loaders (fsl and sunxi). These remain in
the drivers/mtd/spi directory, since they do not contain generic code.

At present some spl_xxx_load_image() functions take a parameter and some

Convert this parameter into a struct so that we can pass all functions the

In raw mode a full sector is to be read even if image covers part of
a sector. Number of sectors are calculated as ROUND_UP(size)/sec_size by FIT
framework. This calculation assumes that image is at the 0th offset of a sector,
which is not true always in FIT case. So, include the image offset while
calculating number of sectors.

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.

When CONFIG_OF_PLATDATA is enabled, we cannot use the u-boot,dm-pre-reloc
device tree property since the device tree is not available. However,
dt-platdata.c only includes devices which would have been present in the
device tree, and we can assume that all such devices are needed for SPL.
If they were not needed, they would have been omitted to save space.
So in this case, bind all devices regardless of the u-boot,dm-pre-reloc
setting. This avoids needing to add a DM_FLAG_PRE_RELOC to every driver,
thus affecting U-Boot proper also.

The next stage boot loader image and the selected FDT can be post-
processed by board/platform/device-specific code, which can include
modifying the size and altering the starting source address before
copying these binary blobs to their final destination. This might be
desired to do things like strip headers or footers attached to the
images before they were packaged into the FIT, or to perform operations
such as decryption or authentication. Introduce new configuration
option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this
feature. If enabled, a platform-specific post-process function must
be provided.

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().

On modern NAND it's more than recommended to have a backup copy of the
u-boot binary to recover from corruption: bitflips are quite common on
MLC NANDs, and the read-disturbance will corrupt your u-boot partitition
more quickly than what you would see on an SLC NAND.
Add an extra Kconfig option to specify the offset of the redundant u-boot
image.
