Some Linux parameters can be set automatically by U-Boot, if it knows the
device being used. For example, since U-Boot knows the serial console
being used, it can add parameters for earlycon and console.
Add support for this.
Note that this is an experimental feature and we will see how useful it
turns out to be. It is very handy for ChromeOS, since otherwise it is very
difficult to manually determine the UART address or port number,
particularly in a script.

On x86 boards Linux uses a block of binary data to provide information

We recently fixed a few issues wrt to controller handling. Add a few
test cases to cover the new code.
- return EFI_DEVICE_ERROR the first time the protocol interface of
the controller is uninstalled, after all the children have been
disconnected. This should make the drivers reconnect
- add tests to verify controllers are reconnected when uninstalling a
protocol fails
- add tests to make sure EFI_NOT_FOUND is returned if a non existent
interface is being removed

Up to now we did not check the return value of DisconnectController.
A previous patch is fixing that taking into account what happened during
the controller disconnect. But that check takes place before our code
is trying to figure out if the interface exists to begin with. In case a
driver is not allowed to unbind -- e.g returning EFI_DEVICE_ERROR, we
will end up returning that error instead of EFI_NOT_FOUND.
Add an extra check on the top of the function to make sure the protocol
interface exists before trying to disconnect any drivers

efi_uninstall_protocol() calls efi_disconnect_all_drivers() but never
checks the return value. Instead it tries to identify protocols that
are still open after closing the ones that were opened with
EFI_OPEN_PROTOCOL_BY_HANDLE_PROTOCOL, EFI_OPEN_PROTOCOL_GET_PROTOCOL
and EFI_OPEN_PROTOCOL_TEST_PROTOCOL.
Instead of doing that, check the return value early and exit if
disconnecting the drivers failed. Also reconnect all the drivers of
a handle if protocols are still found on the handle after disconnecting
controllers and closing the remaining protocols.
While at it fix a memory leak and properly free the opened protocol
information when closing a protocol.

- A number of assorted general fixes and code updates

Flushing kernel image after decompression was taking 113 milliseconds
with U-boot 2022.10. With U-boot 2023.01 and 2023.04, flushing
the same amount of memory takes approx 1.5 seconds. With
U-boot 2023.07-rc6, it takes 6.5 seconds.
powerpc flush_cache() function used to call WATCHDOG_RESET() after
flushing every cacheline. At that time WATCHDOG_RESET() was light
so the operation was almost seamless.
But commit 29caf9305b6 ("cyclic: Use schedule() instead of
WATCHDOG_RESET()") replaced WATCHDOG_RESET() by schedule() and that
started to hurt with U-boot 2022.10.
And in U-boot 2023.07-rc6 that's even worse after
commit 26e8ebcd7cb ("watchdog: mpc8xxx: Make it generic").
In the meantime commit 729c1fe656 ("powerpc: introduce
CONFIG_CACHE_FLUSH_WATCHDOG_THRESHOLD") gives us the opportinity to
only call schedule() every given chunk of data instead of every
cacheline. As explained in that commit there is no point in pinging
the watchdog after every cacheline flush, so lets define a sensible
default chunk size of 4k which matches to size of a page on most
powerpc platforms.
With that new default threshold, the culprit flushing performed after
kernel image decompression now takes 85 milliseconds on a powerpc 8xx.

Uncompressing a 1.7Mbytes FIT image on U-boot 2023.04 takes
approx 7s on a powerpc 8xx.
The same on U-boot 2023.07-rc6 takes approx 28s unless watchdog
is disabled.
During that decompression, LzmaDec_DecodeReal() calls schedule
1.6 million times, that is every 4µs in average.
In the past it used to be a call to WATCHDOG_RESET() which was
just calling hw_watchdog_reset().
But the combination of commit 29caf9305b6 ("cyclic: Use schedule()
instead of WATCHDOG_RESET()") and commit 26e8ebcd7cb ("watchdog:
mpc8xxx: Make it generic") results in an heavier processing.
However, there is absolutely no point in calling schedule() that
often.
By moving and keeping only one call to schedule() in the main
loop the number of calls is reduced to 1.2 million which is still
too much. So add logic to only call schedule every 1024 times.
That leads to a call to schedule approx every 6ms which is still
far enough to entertain the watchdog which has a 1s timeout on
powerpc 8xx.
powerpc 8xx being one of the slowest targets we have today in
U-boot, and most other watchdogs having a timeout of one minutes
instead of one second like the 8xx, this fix should not have
negative impact on other targets.

Instead of using the hard-coded value of 0x1f, use 'TASK_TAG'
macro instead to construct the ucd_req_ptr->header.dword_0
This is in sync with what the Linux UFS driver does, i.e.
set the byte0 equal to TASK_TAG (see [1]).
Setting it to a fixed value of 0x1f is wrong as we define
TASK_TAG as 0 inside u-boot ufs framework. So, instead we
should use the macro value directly.

In case of OF_SEPARATE (!OF_EMBED), the devicetree blob is placed
after _end, and fdt_find_separate() always returns _end. There is
a .bss section after _end and the section is cleared before relocation.
When GD_FLG_SKIP_RELOC is set, relocation is skipped, so the blob is
still in .bss section, but will be cleared. As a result, the devicetree
become invalid.
To avoid this issue, should relocate it regardless of GD_FLG_SKIP_RELOC
in reloc_fdt().

The different CPSW sub-system Ethernet ports have different PHY mode
control registers. In order to allow the modes to get configured
independently only the register for the port in question must be
accessed, otherwise we would just be re-configuring the mode for port 1,
while leaving all others at their power-on defaults. Fix this issue by
adding a port-number based offset to the mode control base register
address based on the fact that the control registers for the different
ports are spaced exactly 0x4 bytes apart.

While NFS is widely used in data centres, and private

A lot of devices already disable it.
Various network protocols should really be opt in, not opt
out, because they add extra size and are potential attack
vectors from a security PoV. In the NFS case it doesn't
really make sense for a lot of devices like tables, SBCs etc.
It's also something we don't really want for SystemReady-IR

the MMC environment partition name. Prior to this patch, the only way
to declare this partition name was by creating a

This setting provides additional flexibility, particularly in cases
where accessing the device-tree is not straightforward (e.g. QEMU).
If undeclared, the device-tree's setting will be used.
