93e310c3a6 board-info: Call sysinfo_detect() before sysinfo_get_str()
The sysinfo_get_str() implementation checks whether the sysinfo was even
detected. In U-Boot proper, sysinfo_detect() is not called anywhere but
on one specific board. Call sysinfo_detect() before sysinfo_get_str() to
make sure the sysinfo is detected and sysinfo_get_str() returns valid
value instead of -EPERM.

10f3e157e8 board-info: Use sysinfo_get()
Replace uclass_first_device_err(UCLASS_SYSINFO, &dev) with sysinfo_get(&dev).
The board_info code may use sysinfo to print board information, so use the
sysinfo functions consistently. The sysinfo_get() is internally implemented
as return uclass_first_device_err(UCLASS_SYSINFO, &dev) anyway, so there is
no functional change.

cb80ff20f2 bootstage: Eliminate when not enabled
When we do not have bootstage enabled, rather than include an empty
dummy function, we just don't reference it.  This saves us space in some
tight builds.  This also shows a few cases where show_boot_progress was

3c9fc23c44 sandbox: don't refer to symbol _init
GCC provides a symbol _init in crti.o on x86_64 and aarch64 but not on
RISC-V. The following lines leads to a build error for sandbox_defconfig on
RISC-V due to the missing symbol:

    common/board_f.c:269:
    #elif defined(CONFIG_SANDBOX) || defined(CONFIG_EFI_APP)
            gd->mon_len = (ulong)&_end - (ulong)_init;

The sandbox code is not copied into the memory allocated using mmap().
Hence we can safely use gd->mon_len = 0 to avoid the reference to _init.

ec0512b173 Revert "lib: introduce HASH_CALCULATE option"
When we think of Kconfig, we usually think of features that we like
to enable or not. Ideally, we wouldn't use Kconfig to fix a build
issue, although sometimes it might make sense. With Kconfig it's hard
to guarantee that the fix is universal. We can only say that it works
for the set of tested configurations. In the majority of cases, it's
preferable to let the linker figure things out for us.

The reverted commit attempted to fix a build issue by adding an
invisible Kconfig option. This is wrong in several ways:

It invents a new Kconfig variable when CONFIG_HASH already
exists for the same purpose.
Second, hash-checksum.c makes use of the hash_progressive_lookup_algo()
symbol, which is only provided with CONFIG_HASH, but this dependency
was not expressed in the reverted patch.

It feels like Kconfig is turning into a listing of all available
source files, and a buffet to 'select' which ones to compile. The
purpose of this revert is to enable the next change to make use of
CONFIG_HASH instead of adding to Kconfig.

This reverts commit 87316da05f.

e2ae483c3b hash: Kconfig option for SHA512 hardware acceleration
Commit a479f103dc ("hash: Allow for SHA512 hardware implementations")
defined function definitions for hardware accelerated SHA384 and SHA512.
If CONFIG_SHA_HW_ACCEL=y, these functions are used.

We already have boards using CONFIG_SHA_HW_ACCEL=y but none implements the
new functions hw_sha384() and hw_sha512().

For implementing the EFI TCG2 protocol we need SHA384 and SHA512. The
missing hardware acceleration functions lead to build errors on boards like
peach-pi_defconfig.

Introduce a new Kconfig symbol CONFIG_SHA512_HW_ACCEL to control if the
functions hw_sha384() and hw_sha512() shall be used to implement the SHA384
and SHA512 algorithms.

95fd977201 env: allow environment to be amended from control dtb
It can be useful to use the same U-Boot binary for multiple purposes,
say the normal one, one for developers that allow breaking into the
U-Boot shell, and one for use during bootstrapping which runs a
special-purpose bootcmd. Or one can have several board variants that
can share almost all boot logic, but just needs a few tweaks in the
variables used by the boot script.

To that end, allow the control dtb to contain a /config/enviroment
node (or whatever one puts in fdt_env_path variable), whose
property/value pairs are used to update the run-time environment after
it has been loaded from its persistent location.

The indirection via fdt_env_path is for maximum flexibility - for
example, should the user wish (or board logic dictate) that the values
in the DTB should no longer be applied, one simply needs to delete the
fdt_env_path variable; that can even be done automatically by
including a

  fdt_env_path = "";

property in the DTB node.

58b504e5e1 Revert "spl: Drop bd_info in the data section"
This reverts commit 38d6b7ebda.

struct global_data contains a pointer to the bd_info structure. This
pointer was populated spl_set_bd() to a pre-allocated bd_info in the
".data" section. The referenced commit replaced this mechanism to one
that uses malloc(). That new mechanism is only used if SPL_ALLOC_BD=y.
which very few boards do.

The result is that (struct global_data)->bd is NULL in SPL on most
platforms. This breaks falcon mode, since arch_fixup_fdt() tries to
access (struct global_data)->bd and set the "/memory" node in the
devicetree. The result is that the "/memory" node contains garbage
values, causing linux to panic() as it sets up the page table.

Instead of trying to fix the mess, potentially causing other issues,
revert to the code that worked, while this change is reworked.

033ac4ebba image-fit: Accept OP-TEE images when booting a FIT
OP-TEE images are normally packaged with
	type = "tee;
	os = "tee";

However, fit_image_load() thinks that is somehow invalid. However if
they were declared as type = "kernel", os = "linux", fit_image_load()
would happily accept them and allow the boot to continue. There is no
technical limitation to excluding "tee".

Allowing "tee" images is useful in a boot flow where OP-TEE is
executed before linux.

In fact, I think it's unintuitive for a "load"ing function to also do
parsing and contain a bunch ad-hoc heuristics that only its caller
might know. But I don't make the rules, I just write fixes. In more
polite terms: refactoring the fit_image API is beyond the scope of
this change.

47b6f7f845 image-fit: Accept IH_TYPE_FIRMWARE in fit_image_load() as valid
Consider the following FIT:

	images {
		whipple {};
	};
	configurations {
		conf-1 {
			firmware = "whipple";
		};
	};

Getting the 'firmware' image with fit_image_load() is not possible, as
it doesn't understand 'firmware =' properties. Although one could pass
IH_TYPE_FIRMWARE for 'image_type', this needs to be converted to a
"firmware" string for FDT lookup -- exactly what this change does.

60138aa87c spl: LOAD_FIT_FULL: Relocate FDT for u-boot payloads
U-Boot expects the FDT to be located right after the _end
linker symbol (see fdtdec.c: board_fdt_blob_setup())

The "basic" LOAD_FIT path is aware of this limitation, and relocates
the FDT at the expected location. Guessing the expected location
probably only works reliably on 32-bit arm, and it feels like a hack.
One proposal would be to pass the FDT address to u-boot
(e.g. using 'r2' on arm platforms).

The variable is named "fdt_hack" to remind future contributors that,
"hey! we should fix the underlying problem". However, that is beyond
the scope of this patch.

2eaae17bc9 spl: LOAD_FIT_FULL: Do not hard-code os to IH_OS_U_BOOT
The information on the OS should be contained in the FIT, as the
self-explanatory "os" property of a node under /images. Hard-coding
this to U_BOOT might send us down the wrong path later in the boot
process.

18fd663c63 spl: LOAD_FIT_FULL: Fix selection of the "fdt" node
The correct FDT to use is described by the "fdt" property of the
configuration node. When the fit_unamep argument to fit_image_load()
is "fdt", we get the "/images/fdt" node. This is incorrect, as it
ignores the "fdt" property of the config node, and in most cases,
the "/images/fdt" node doesn't exist.

Use NULL for the 'fit_unamep' argument. With NULL, fit_image_load()
uses the IH_TYPE_FLATDT value to read the config property "fdt",
which points to the correct FDT node(s).

fit_image_load() should probably be split into a function that reads
an image by name, and one that reads an image by config reference. I
don't make those decisions, I just point out the craziness.

d442f69399 common: fit: Add weak board_fit_config_name_match
Several architectures had a default board_fit_config_name_match already;
this provides a generic weak version. We default to rejecting all configs.
This will use the FIT's default config, instead of the first config. This
may result in boot failures if there are multiple configurations and the
first config is *not* the default.

df51ae767e Kconfig: Document the limitations of the simple SPL_LOAD_FIT path
The "simple" SPL_LOAD_FIT path is the most compliant with the format
documented in doc/uImage.FIT/source_file_format.txt. The other two
paths to load a FIT are SPL_LOAD_FIT_FULL and the "bootm" command.

Since the Kconfig menu is the most likely place for a new user to see
these options, it seems like the most logical candidate to document
the limitations. This documents the _known_ issues, and is not
intended to be a complete list of all follies.

f0a6ec3656 spl: fit: Don't overwrite previous loadable if "load" is missing
spl_load_fit_image() will try to load an image at the address given
in the "load" property. Absent such property, it uses

	image_info->load_addr

Correct use of this is demonstrated in spl_fit_append_fdt(), which
resets the 'load_addr' before each spl_load_fit_image() call.

On the other hand loading "loadables" loop in spl_load_simple_fit()
completely ignores this. It re-uses the same structure, but doesn't
reset load_addr. If loadable [i] does not have a "load" property, its
load address defaults to load_addr, which still contains the address
of loadable [i - 1].

A simple solution is to treat NULL as an invalid load address. The
caller can set load_addr = 0 to request an abort if the "load"
property is absent.
