On x86 boards Linux uses a block of binary data to provide information
about the command line, memory map, etc. Provide a way to store this in
the bootflow so it can be passed on to the OS.
No attempt is made to generalise the code, since other archs don't need
this information. The field is present always, though, to avoid needing
accessors or #ifdefs when building code on other archs.

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

controllers and closing the remaining protocols.

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 29caf9305b ("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 26e8ebcd7c ("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 29caf9305b ("cyclic: Use schedule()
instead of WATCHDOG_RESET()") and commit 26e8ebcd7c ("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.

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

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.

To quote the author:
This series provides a means to edit board configuration in U-Boot in a
graphical manner. It supports multiple menu items and allows moving
between them and selecting items. The configuration is defined in a data
format so that code is not needed in most cases. This allows the board
configuration to be provided in the devicetree.
This is still at an early stage, since it only supports menus. Numeric
values are not supported. Most importantly it does not yet support
loading or saving the configuration selected by the user.
To try it out you can use something like:
./tools/expo.py -e test/boot/files/expo_layout.dts \
-l test/boot/files/expo_layout.dts -o cedit.dtb
./u-boot -Tl -c "cedit load hostfs - cedit.dtb; cedit run"
Use the arrow keys to move between menus, enter to open a menu, escape
to exit.
Various minor fixes and improvements are provided in this series:
- Update STB TrueType library to latest
- Support clearing part of the video display
- Support multiple livetrees loaded at runtime
- Support loading and allocating a file
- Support proper measuring of text in expo
- Support simple themes for expo
This was brought in in 2016 and a number of changes have been made since
then. There does not seem to be much change in functionality, but it is
a good idea to update from time to time.
