Section "59.5.3 Configure Watchdog" provides the following example:

DisableInterrupts; //disable global interrupt
WDOG_CNT = 0xD928C520; //unlock watchdog

  WDOG_CS_WIN(0) | WDOG_CS_UPDATE(1);
while(WDOG_CS[RCS]==0); //wait until new configuration takes effect
EnableInterrupts; //enable global interrupt

Update U-Boot WDOG driver to align with i.MX7ULP reference manual.

Use 32 bits accessing to CS register. According to RM, the bits in
this register only can write once after unlock. So using 8 bits access
will cause problem.

3 years agotools: Use a single target-independent config to enable OpenSSL
Alexandru Gagniuc [Wed, 14 Jul 2021 22:05:47 +0000 (17:05 -0500)]
tools: Use a single target-independent config to enable OpenSSL

Host tool features, such as mkimage's ability to sign FIT images were
enabled or disabled based on the target configuration. However, this
misses the point of a target-agnostic host tool.

A target's ability to verify FIT signatures is independent of
mkimage's ability to create those signatures. In fact, u-boot's build
system doesn't sign images. The target code can be successfully built
without relying on any ability to sign such code.

Conversely, mkimage's ability to sign images does not require that
those images will only work on targets which support FIT verification.
Linking mkimage cryptographic features to target support for FIT
verification is misguided.

Without loss of generality, we can say that host features are and
should be independent of target features.

While we prefer that a host tool always supports the same feature set,
we recognize the following
  - some users prefer to build u-boot without a dependency on OpenSSL.
  - some distros prefer to ship mkimage without linking to OpenSSL

To allow these use cases, introduce a host-only Kconfig which is used
to select or deselect libcrypto support. Some mkimage features or some
host tools might not be available, but this shouldn't affect the
u-boot build.

I also considered setting the default of this config based on
FIT_SIGNATURE. While it would preserve the old behaviour it's also
contrary to the goals of this change. I decided to enable it by
default, so that the default build yields the most feature-complete
mkimage.

At the moment android_image_get_kcomp() can automatically detect
LZ4 compressed kernels and the compression specified in uImages.
However, especially on ARM64 Linux is often compressed with GZIP.
Attempting to boot an Android image with a GZIP compressed kernel

  Starting kernel ...

   ...

Note the 1f8b, which are the "magic" bytes for GZIP images.

U-Boot already has the image_decomp_type() function that checks for
the magic bytes of bzip2, gzip, lzma and lzo. It's easy to make use
of it here to increase the chance that we do the right thing and the

fit: Load DTO into temporary buffer and ignore load address

The current fitImage DTO implementation expects each fitImage image
subnode containing DTO to have 'load' property, pointing somewhere
into memory where the DTO will be loaded. The address in the 'load'
property must be different then the base DT load address and there
must be sufficient amount of space between those two addresses.
Selecting and using such hard-coded addresses is fragile, error
prone and difficult to port even across devices with the same SoC
and different DRAM sizes.

The DTO cannot be applied in-place because fdt_overlay_apply_verbose()
modifies the DTO when applying it onto the base DT, so if the DTO was
used in place within the fitImage, call to fdt_overlay_apply_verbose()
would corrupt the fitImage.

Instead of copying the DTO to a specific hard-coded load address,
allocate a buffer, copy the DTO into that buffer, apply the DTO onto
the base DT, and free the buffer.

The upside of this approach is that it is no longer necessary to
select and hard-code specific DTO load address into the DTO. The
slight downside is the new malloc()/free() overhead for each DTO,
but that is negligible (*).

U-Boot from SPI NOR at 1 MHz instead of 40 MHz.

prefering this parameter instead of the one specified in device-tree.

I am not sure what else will be affected on other boards with such a
