The normal way of loading u-boot is as a FIT, so configure u-boot.img as
the SPL playload.
The u-boot-with-spl.bin target will add padding according to
CONFIG_SPL_MAX_SIZE which defaults to 64KB on the AST2600.
With this the following simple steps can be used to build and boot a
system:
make u-boot-with-spl.bin
truncate -s 64M u-boot-with-spl.bin
qemu-system-arm -nographic -M ast2600-evb \
-drive file=u-boot-with-spl.bin,if=mtd,format=raw

The HACE driver lacks support for all the hash types, causing boot to
fail with the default FIT configuration which uses CRC32.
Additionally the Qemu model or the u-boot driver is unable to correctly
compute the SHA256 hash used in a FIT.
Disable HACE by default while the above issues are worked out to enable
boot testing in Qemu.

- Convert a large number of CONFIG symbols to Kconfig. Of note is a
large chunk of USB symbols (and dead code removal), ensuring all
SPL/TPL/VPL symbols have an appropriate dependency, largely (but not
entirely) removing the testing of CONFIG_SPL_BUILD in board headers,
and allowing CONFIG_EXTRA_ENV_TEXT and CONFIG_EXTRA_ENV_SETTINGS to
co-exist as this facilities migration of many platforms.
The commit b583348ca8 ("image: fit: Align hash output buffers") places
the hash output buffer at the .bss section. However, AST2600 by default
executes SPL in the NOR flash XIP way. This results in the hash output
cannot be written to the buffer as it is located at the R/X only region.
We need to move the .bss section out of the SPL body to the DRAM space,
where hash output can be written to. This patch includes:
- Define the .bss section base and size
- A new SPL linker script is added with a separate .bss region specified
- Enable CONFIG_SPL_SEPARATE_BSS kconfig option

Asking if the alias we found actually points at the device tree node
we passed in (in the guise of its offset from blob) can be done simply
by asking if the fdt_path_offset() of the alias' path is identical to
offset.
In fact, the current method suffers from the possibility of false
negatives: dtc does not necessarily emit a phandle property for a node
just because it is referenced in /aliases; it only emits a phandle
property for a node if it is referenced in <angle brackets>
somewhere. So if both the node we passed in and the alias node we're
considering don't have phandles, fdt_get_phandle() returns 0 for both.
Since the proper check is so simple, there's no reason to hide that
behind a config option (and if one really wanted that, it should be
called something else because there's no need to involve phandle in
the check).

Note that the da850evm platforms were violating the "only use one" rule
here, and so now hard-code their BSS limit.

AST2600 leverages the FIT hash/signature verification to fulfill
secure boot trust chain. To improve the performance and save SW
code size for those crypto operations, the two HW crypto engine,
HACE and ACRY, are enabled.
However, both of the engines can only access to data stored in
DRAM space. Therefore, we need to move the FIT image into DRAM
before the booting.
This patch update the CONFIG_BOOTCOMMAND to execute the pre-defined
ENV variable which consists of FIT image copy to memory and booting.
