To quote the author:
This patchset adds the basic infrastructure to periodically execute
code, e.g. all 100ms. Examples for such functions might be LED blinking
etc. The functions that are hooked into this cyclic list should be
small timewise as otherwise the execution of the other code that relies
on a high frequent polling (e.g. UART rx char ready check) might be
delayed too much. This patch also adds the Kconfig option
CONFIG_CYCLIC_MAX_CPU_TIME_US, which configures the max allowed time
for such a cyclic function. If it's execution time exceeds this time,
this cyclic function will get removed from the cyclic list.
How is this cyclic functionality executed?
This patchset integrates the main function responsible for calling all
registered cyclic functions cyclic_run() into the common WATCHDOG_RESET
macro. This guarantees that cyclic_run() is executed very often, which
is necessary for the cyclic functions to get scheduled and executed at
their configured periods.
This cyclic infrastructure will be used by a board specific function on
the NIC23 MIPS Octeon board, which needs to check periodically, if a
PCIe FLR has occurred.
Ideas how to continue:
One idea is to rename WATCHDOG_RESET to something like SCHEDULE and
move the watchdog_reset call into this cyclic infrastructure as well.
Or to perhaps move the shell UART RX ready polling to a cyclic
function.
It's also possible to extend the "cyclic" command, to support the
creation of periodically executed shell commands (for testing etc).

spi: aspeed: Add ASPEED SPI controller driver
Add ASPEED BMC FMC/SPI memory controller driver with
spi-mem interface for AST2500 and AST2600 platform.
There are three SPI memory controllers embedded in an ASPEED SoC.
- FMC: Named as Firmware Memory Controller. After AC on, MCU ROM
fetches initial device boot image from FMC chip select(CS) 0.
- SPI1: Play the role of a SPI Master controller. Or, there is a
dedicated path for HOST(X86) to access its BIOS flash mounted
under BMC. spi-aspeed-smc.c implements the control sequence when
SPI1 is a SPI master.
- SPI2: It is a pure SPI flash controller. For most scenarios, flashes
mounted under it are for pure storage purpose.
ASPEED SPI controller supports 1-1-1, 1-1-2 and 1-1-4 SPI flash mode.
Three types of command mode are supported, normal mode, command
read/write mode and user mode.
- Normal mode: Default mode. After power on, normal read command 03h or
13h is used to fetch boot image from SPI flash.
- AST2500: Only 03h command can be used after power on
or reset.
- AST2600: If FMC04[6:4] is set, 13h command is used,
otherwise, 03h command.
The address length is decided by FMC04[2:0].
- Command mode: SPI controller can send command and address
automatically when CPU read/write the related remapped
or decoded address area. The command used by this mode
can be configured by FMC10/14/18[23:16]. Also, the
address length is decided by FMC04[2:0]. This mode will
be implemented in the following patch series.
- User mode: It is a traditional and pure SPI operation, where
SPI transmission is controlled by CPU. It is the main
mode in this patch.
Each SPI controller in ASPEED SoC has its own decoded address mapping.
Within each SPI controller decoded address, driver can assign a specific
address region for each CS of a SPI controller. The decoded address
cannot overlap to each other. With normal mode and command mode, the
decoded address accessed by the CPU determines which CS is active.
When user mode is adopted, the CS decoded address is a FIFO, CPU can
send/receive any SPI transmission by accessing the related decoded
address for the target CS.
This patch only implements user mode initially. Command read/write
mode will be implemented in the following patches.

xilinx: zynq: Disable LMB for mini configurations
There shouldn't be a reason to have LMB on for these configurations.
LMB was already disabled for ZynqMP by commit 0063487a5b60 ("configs:
zynqmp: Disable LMB for mini u-boot").

cmd: bdinfo: Enable dumping lmb data when LMB is enabled
The commit 9996cea75f5a ("lmb/bdinfo: dump lmb info via bdinfo") added
support for dumping LMB information as the part of bdinfo. But code itself
should be called only when LMB is enabled.
fpga: zynq: Remove post config info message for SPL
The drivers informs the user that a post config was not run after FPGA
configuration. This message is unnecessary in SPL because the
ps7_post_config function is called via spl_board_prepare_for_boot
function before jump_to_image_no_args function from board_init_r
function.
Move arm twd timer driver from zynq to generic location.
DM timer drivers are designed differently to original driver. Timer is
counting up and not down.
Information about clock rates are find out in timer_pre_probe() that's
why there is no need to get any additional information from DT in the
driver itself (only register offset).

Merge branch '2022-09-02-assorted-improvements' into next
- DM RTC improvements that should help in CI, allow disabling LTO from
the make line, add extension (cape, etc) support to distro bootcmd,
add a pause command and re-enable ARM v4T support.

dm: rtc: Try to handle the localtime() race
At present the sandbox timer uses localtime() which can jump around twice
a year when daylight-saving time changes.
It would be tricky to make use of gmtime() since we still need to present
the time in local time, as seems to be required by U-Boot's RTC interface.
The problem can only happen once, so use a loop to detect it and try
again. This should be sufficient to detect either a change in the 'second'
value, or a daylight-saving change. We can assume that the latter also
incorporates a 'second' change, so there is no need to loop more than
twice.

dm: rtc: Avoid a race in the rtc_reset test
Since resetting the RTC on sandbox causes it to read the base time from
the system, we cannot rely on this being unchanged since it was last read.
Allow for a one-second delay.

Makefile: Allow LTO to be disabled for a build
LTO (Link-Time Optimisation) is an very useful feature which can
significantly reduce the size of U-Boot binaries. So far it has been
made available for selected ARM boards and sandbox.
However, incremental builds are much slower when LTO is used. For example,
an incremental build of sandbox takes 2.1 seconds on my machine, but 6.7
seconds with LTO enabled.
Add a NO_LTO parameter to the build, similar to NO_SDL, so it can be
disabled during development if needed, for faster builds.
Add some documentation about LTO while we are here.

arm: ARMv4 assembly compatibility
There is currently a problem that U-Boot can not work on ARMv4
because assembly imlementations of memcpy() and some other functions
use "bx lr" instruction that is not available on ARMv4 ("mov pc, lr"
should be used instead).
A working preprocessor-based solution to this problem is found in
arch/arm/lib/relocate.S. Move it to the "ret" macro in
arch/arm/include/asm/assembler.h and change all "bx lr" code
to "ret lr" in functions that may run on ARMv4. Linux source code
deals with this problem in the same manner.

This command is being introduced with the goal of allowing user-friendly
"generic use case" U-Boot builds to pause until user input under some
situations.
The main use case would be when a boot failure happens, to pause until
the user has had time to acknowledge the current state.
Tested using:
make && ./u-boot -v -T -c 'ut lib lib_test_hush_pause'
