c7674fcb07 Makefile: Tidy up SPL dtb production
Use the SPL_NAME variable to simplify the rules. Drop the SPL targets
clean-files since the SPL and TPL dts/ directories are removed by
existing rules. Move the SPL rules into a new spl_dtbs to avoid the
complicated $(if) construct.

Also drop unused pieces from the 'targets' variable.

With this, SPL and TPL have separate dtbs which respect the various
u-boot,dm-spl / u-boot,dm-tpl tags.

de3e372abd Makefile: Build SPL dtbs in the spl/ directory
Rather than putting these in the top-level dts/ directory (which is

53db2eec7a Makefile: Build a separate .dtb for TPL
At present both SPL and TPL use the same devicetree binary. While there
is logic to run fdtgrep separately on each one, it does not actually
happen.

Add a new TPL rule and use that instead. Make this rule conditional on
there actually being a TPL. Do the same for SPL for consistency.

Note that the SPL and TPL dtbs are build by a Makefule rule used for
U-Boot proper. This is the 'dtbs' target in dts/Makefile. So the check
for CONFIG_TPL_BUILD in cmd_fdtgrep never actually works at present.

We don't support CONFIG_OF_EMBED for TPL at present.

4366a2440a crypto: Fix the logic to calculate hash with authattributes set
RFC 2315 Section 9.3 describes the message digesting process. The
digest calculated depends on whether the authenticated attributes are
present. In case of a scenario where the authenticated attributes are
present, the message digest that gets signed and is part of the pkcs7
message is computed from the auth attributes rather than the contents
field.

Check if the auth attributes are present, and if set, use the auth
attributes to compute the hash that would be compared with the
encrypted hash on the pkcs7 message.

In the scenario where the esl file is to be embedded in an overlay,
this can be done through the following command
mkeficapsule -O -K <pub_key.esl> -D <dtb>

47d2b3b9c9 efi_loader: Remove unconditional installation of file2 protocol for initrd
Up to now we install the EFI_LOAD_FILE2_PROTOCOL to load an initrd
unconditionally. Although we correctly return various EFI exit codes
depending on the file status (i.e EFI_NO_MEDIA, EFI_NOT_FOUND etc), the
kernel loader only falls back to the cmdline interpreted initrd if the
protocol is not installed.

This creates a problem for EFI installers, since they won't be able to
load their own initrd and start the installation.

A following patch introduces a different logic where we search for an
initrd path defined in an EFI variable named 'Initrd####'.
If the bootmgr is used to launch the EFI payload, we'll will try to match
the BootCurrent value and find the corresponding initrd
(i.e Boot0000 -> Initrd0000 etc). If the file is found, we'll install
the required protocol which the kernel's efi-stub can use and load our
initrd.

ec1add1e51 dm: core: Inline a few ofnode functions in SPL
A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.

To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.

Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.

1dc53ce71d sandbox: test: Add a second SPI slave on sandbox_spi bus
Place a second spi slave on the sandbox_spi bus, to be used by the
spi_claim_bus() testcase we are about to introduce. We need to make sure
that jumping between slaves calling spi_claim_bus() sets the bus speed and
mode appropriately. Use different max-hz and mode properties for this new
slave.

Also, update sandbox_spi cs_info call to allow activity on CS0/CS1 and
adapt dm_test_spi_find() testcase for this new setup.

1f6d618bb1 sandbox: spi: Drop unused sandbox_spi_parse_spec function
Commit 1289e96797 ("sandbox: spi: Drop command-line SPI option") dropped
support for specifying SPI devices on the command line, removing the only
user of sandbox_spi_parse_spec(). Remove the function too.

Before executing code that we have loaded from a file we need to flush the
data cache and invalidate the instruction flash.

Implement functions flush_cache() and invalidate_icache_all().

c589132a1d fdt: Use phandle to distinguish DT nodes with same name
While assigning the sequence number to subsystem instances by reading the
aliases property, only DT nodes names are compared and not the complete
path. This causes a problem when there are two DT nodes with same name but
have different paths.

In arch/arm/dts/k3-am65-main.dtsi there are two USB controllers with the
same device tree node name but different path. When aliases are defined for
these USB controllers then fdtdec_get_alias_seq() fails to pick the correct
instance for a given index.

fdt_path_offset() function is slow and this would effect the U-Boot
startup. To avert the time penalty on all boards, apply this extra check
only when required by using a config option.

Fix it by comparing the phandles of DT nodes after the node names match,
under a config option.
