kontron-sl-mx8mm: Let CONFIG_SPL_FIT_IMAGE_TINY be selected
When CONFIG_IMX_HAB is selected the 'hab_status' command reports several
error events, indicating that the BootROM failed to authenticate the SPL.
After inspecting the content of the memory location that corresponds to
the DTB load address, the content did not match with the DTB binary,
showing that some kind of memory corruption/overlap occurred.
Letting the CONFIG_SPL_FIT_IMAGE_TINY option to be selected causes the
DTB to be properly placed into RAM and no more overlap occurs.
With this change, the 'hab_status' command returns no more error events,
which indicates that the BootROM succeeded to authenticate the SPL.

cmd: fdt: Add support for reading stringlist property values
The fdt command currently handles stringlists as strings in 'fdt get value'
subcommand. Since strings in FDT stringlists are separated by '\0', only
the first value gets inserted into the environment variable passed to the
'fdt get value' command.
Example, consider the following DT snippet:
/ { compatible = "foo", "bar" };
The following command only reports the first string in stringlist:
=> fdt get value var / compatible ; print var
foo
It is not possible to assign list of null-terminated strings into U-Boot
environment variable. Add optional 'index' parameter to the subcommand
'fdt get value <var> <path> <prop> [<index>]' which lets user specify which
string within the stringlist should be assigned into the 'var' variable.
The default value of 'index' is 0 in case it is not present. This way the
'fdt' command API does not change and existing scripts are not broken.
The following command now reports the Nth string in stringlist, counting
from zero:
=> fdt get value var / compatible 1 ; print var
bar

arm: mvebu: turris_omnia: Allow to use second serial port
Turris Omnia has two serial ports. Both are already specified in device
tree file. But U-Boot by default does not allow to use more than one serial
port unless CONFIG_SERIAL_PROBE_ALL is not enabled.
After enabling CONFIG_SERIAL_PROBE_ALL, U-Boot see also second serial port
(but is inactive by default):
=> coninfo
List of available devices:
serial@12000 00000007 IO stdin stdout stderr
serial@12100 00000007 IO
To allow simultaneously to use more input / output devices it is needed to
enable CONFIG_CONSOLE_MUX option.
With CONFIG_CONSOLE_MUX it is possible to call:
=> setenv stdout 'serial@12000,serial@12100'
And U-Boot output is then visible on both serial ports.

tools: termios_linux.h: Fix compilation on non-glibc systems
TCGETS2 is defined in header file asm/ioctls.h provided by linux kernel.
On glib systems it is automatically included by some other glibc include
header file and therefore TCGETS2 is present in termios_linux.h when
linux kernel provides it.
On non-glibc systems (e.g. musl) asm/ioctls.h is not automatically included
which results in the strange error that BOTHER is supported, TCGETS2 not
defined and struct termios does not provide c_ispeed member.

tools/kwboot.c:662:6: error: 'struct termios' has no member named 'c_ospeed'

Fix this issue by explicitly including asm/ioctls.h file which provides
TCGETS2 macro (if supported on selected architecture) to not depending on
glibc auto-include behavior and because termios_linux.h requires it.
With this change it is possible compile kwboot with musl libc.

arm: mvebu: turris_mox: Add support for distroboot $fdt_addr
$fdt_addr is mandatory for systems which provides DTB in HW (e.g. ROM) and

Turris Mox contains DTB binary in SPI NOR memory at "dtb" partition which
starts at offset 0x7f0000 and is 0x10000 bytes long.
Armada 3700 CPU does not allow mapping SPI NOR memory into physical address

board: turris: Initialize serial# env
Store serial number from atsha cryptochip into the serial# env variable.
U-Boot automatically puts content of this variable into the root device
tree property serial-number when booting Linux kernel. Refactor turris
atsha code and from turris_atsha_otp_get_serial_number() function returns
directly string suitable for printing or storing into device tree. Because
during different boot stages is env storage read-only, it is not possible
to always store serial number into env storage. So introduce a new function
turris_atsha_otp_init_serial_number() which is called at later stage and
which ensures that serial number is correctly stored into env.

U-Boot fuse API is currently implemented only for A38x and A37xx SoCs.
Additionally Armada 3700 BootROM rejects signed trusted image when secure

OTP secure bits may have burned also boot device source. Check it also and

fdt_support: add optional board_rng_seed() hook
A recurring theme on LKML is the boot process deadlocking due to some
process blocking waiting for random numbers, while the kernel's
Cryptographic Random Number Generator (crng) is not initalized yet,
but that very blocking means no activity happens that would generate
the entropy necessary to finalize seeding the crng.
This is not a problem on boards that have a good hwrng (when the
kernel is configured to trust it), whether in the CPU or in a TPM or
elsewhere. However, that's far from all boards out there. Moreover,
there are consumers in the kernel that try to obtain random numbers
very early, before the kernel has had any chance to initialize any
hwrng or other peripherals.
Allow a board to provide a board_rng_seed() function, which is
responsible for providing a value to be put into the rng-seed property
under the /chosen node.
The board code is responsible for how to actually obtain those
bytes.
- One possibility is for the board to load a seed "file" from
somewhere (it need not be a file in a filesystem of course), and
then ensure that that the same seed file does not get used on
subsequent boots.
* One way to do that is to delete the file, or otherwise mark it as
invalid, then rely on userspace to create a new one, and living
with the possibility of not finding a seed file during some boots.
* Another is to use the scheme used by systemd-boot and create a new
seed file immediately, but in a way that the seed passed to the
kernel and the new (i.e. next) seed cannot be deduced from each
other, see the explanation at
https://lore.kernel.org/lkml/20190929090512.GB13049@gardel-login/
and the current code at
https://github.com/systemd/systemd/blob/main/src/boot/efi/random-seed.c
- The board may have an hwrng from which some bytes can be read; while
the kernel can also do that, doing it in U-Boot and providing a seed
ensures that even very early users in the kernel get good random
numbers.
- If the board has a sensor of some sort (temperature, humidity, GPS,
RTC, whatever), mixing in a reading of that doesn't hurt.
- etc. etc.
These can of course be combined.
The rng-seed property is mixed into the pool used by the linux
kernel's CRNG very early during boot. Whether it then actually
contributes towards the kernel considering the CRNG initialized
depends on whether the kernel has been configured with
CONFIG_RANDOM_TRUST_BOOTLOADER (nowadays overridable via the
random.trust_bootloader command line option). But that's for the BSP
developer to ultimately decide.
So, if the board needs to have all that logic, why not also just have
it do the actual population of /chosen/rng-seed in ft_board_setup(),
which is not that many extra lines of code?
I considered that, but decided handling this logically belongs in
fdt_chosen(). Also, apart from saving the board code from the few
lines of boilerplate, doing it in ft_board_setup() is too late for at
least some use cases. For example, I want to allow the board logic to
decide
ok, let's pass back this buffer and use that as seed, but also let's
set random.trust_bootloader=n so no entropy is credited.
This requires the rng-seed handling to happen before bootargs
handling. For example, during the very first boot, the board might not
have a proper seed file, but the board could still return (a hash of)
some CPU serial# or whatnot, so that at least no two boards ever get
the same seed - the kernel always mixes in the value passed in
rng-seed, but if it is not "trusted", the kernel would still go
through the same motions as it would if no rng-seed was passed before
considering its CRNG initialized. I.e., by returning that
unique-to-this-board value and setting random.trust_bootloader=n, the
board would be no worse off than if board_rng_seed() returned nothing
at all.
UEFI block devices can either mirror U-Boot's internal devices or be
provided by an EFI application like iPXE.
When ConnectController() is invoked for the EFI_BLOCK_IO_PROTOCOL
interface for such an application provided device we create a virtual
U-Boot block device of type "efi_blk".
Currently we do not call ConnectController() when handles for U-Boot's
internal block devices are created. If an EFI application calls
ConnectController() for a handle relating to an internal block device,
we erroneously create an extra "efi_blk" block device.
E.g. the UEFI shell has a command 'connect -r' which calls
ConnectController() for all handles with device path protocol.
In the Supported() method of our EFI_DRIVER_BINDING_PROTOCOL return
EFI_UNSUPPORTED when dealing with an U-Boot internal device.
