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.
Change efi_delete_handle() to not free EFI handles twice.
This change tries to resolved an issue seen since U-Boot v2022.07
in which ExitBootService() attempts to release some EFI handles twice.
The issue was seen booting a EFI shell that invokes 'connect -r' and
then boots a Linux kernel. Execution of connect command makes EFI
subsystem to bind a block device for each root block devices EFI handles.
However these EFI device handles are already bound to a driver and we
can have 2 registered devices relating to the same EFI handler. On
ExitBootService(), the loop removing the devices makes these EFI handles
to be released twice which corrupts memory.
This patch prevents the memory release operation caused by the issue but
but does not resolve the underlying problem.

Removes hwlocks properties from stm32mp151 pinctrl node. These locks
could be used for other purpose, depending on board and software
configuration hence do not enforce their use to protect pinctrl
devices.
This patch is an alignment with Linux device tree with v6.0 as the
hwsem support wasn’t yet added in pincontrol in kernel. It avoids
issues when the Linux kernel is started with the U-Boot device tree.

board: freescale: p1_p2_rdb_pc: Turn off watchdog before reset
P1/P2 RDB boards have external max6370 watchdog connected to CPLD and this
watchdog is not deactivated on board reset. So if it is active during board
reset, it can trigger another reset when CPU is booting U-Boot. To prevent
possible infinite reset loop caused by external watchdog, turn it off
before reset.
Do it via a new board_reset_prepare() callback which is called from
do_reset() function before any reset sequence.

board: freescale: p1_p2_rdb_pc: Avoid usage of CPLD's system reset register
CPLD's system reset register is buggy and requires workaround in U-Boot.
So use this kind of board reset only when there is no other reset option.
Introduce a new board_reset_last() callback which is last-stage
board-specific reset and implement CPLD's system reset in this new
board_reset_last() callback instead of board_reset() callback.

board: freescale: p1_p2_rdb_pc: Add workaround for non-working watchdog
If watchdog timer was already set to non-disabled value then it means that
watchdog timer was already activated, has already expired and caused CPU
reset. If this happened then due to CPLD firmware bug, writing to wd_cfg
register has no effect and therefore it is not possible to reactivate
watchdog timer again. Watchdog starts working again after CPU reset via
non-watchdog method.
Implement this workaround (reset CPU when it was reset by watchdog) to make
watchdog usable again. Watchdog timer logic on these P1/P2 RDB boards is
connected to CPLD, not to SoC itself.
Note that reset does not occur immediately after calling do_reset(), but
after few ms later as real reset is done by CPLD. So it is normal that
function do_reset() returns. Therefore hangs after calling do_reset() to
prevent CPU execution of the rest U-Boot code.

board: freescale: p1_p2_rdb_pc: Add workaround for board reset reboot loop
CPLD's system reset register on P1/P2 RDB boards is not autocleared after
flipping it. If this register is set to one in 100ms after reset starts
then CPLD triggers another CPU reset.
This means that trying to reset board via CPLD system reset register cause
reboot loop. To prevent this reboot loop, the only workaround is to try to
clear CPLD's system reset register as early as possible. U-Boot is already
doing it in its board_early_init_f() function, which seems to be enough as
register is cleared prior CPLD triggers another reset.
But board_early_init_f() is not called from SPL and therefore usage of SPL
can cause reboot loop.
To prevent reboot loop when using SPL, call board_early_init_f() function
in SPL too. For accessing CPLD memory space it is needed to have CPLD entry
in TLB.
With this change it is possible to trigger board reset via CPLD's system
reset register on P2020 RDB board.

System reset via the SRST extension in the SBI should be the default.
The driver checks if the extension is available when probing.
So there is no risk in enabling it.

ddr: fsl: Make bank_addr_bits reflect actual bits
In both the Freescale DDR controller and the SPD spec, bank address bits
are stored as the number of bank address bits minus 2. For example, if a
chip had 8 banks (3 total bank address bits), the value of
bank_addr_bits would be 1. This is rather surprising for users
configuring their memory manually, since they can't set bank_addr_bits
to the actual number of bank address bits. Rectify this.
There is at least one example of this kind of mistake already, in
board/freescale/t102xrdb/ddr.c. The documented MT40A512M8HX has two bank
address bits, but bank_addr_bits was set to 2, implying 4 bank address
bits. Such a value is reserved in BA_BITS_CS, but I suspect the
controller simply ignores the top bit, making this kind of mistake
harmless, if misleading.

ddr: fsl: Reduce the size of interactive options
The interactive mode uses large several tables of options which can be
configured. However, much of the contents of these tables are
repetetive. For example, no struct is larger than half a kilobyte, so
the offset only takes up 9 bits. Similarly, the size is only ever 4 or
8, and printhex is a boolean. Reduce the size of these fields. This
reduces the size of the options tables by around 10 KiB. However, the
largest contributor to the size of the options tables is the use of a
pointer for the strings. A better approach would be to use a separate
array of strings, and store an integer index in the options tables.
However, this would require a large re-architecting of this file.
