Provide tests to check the behavior of the multiplexer framework.

Two sets of tests are added. One is using an emulated multiplexer driver
that can be used to test basic functionality like select, deselect, etc.
The other is using the mmio mux which adds tests specific to it.

Pull request for UEFI sub-system for efi-2021-01-rc2

A software RTC driver is supplied for UEFI SCT testing.

The following UEFI related bugs are fixed:

* correct handling of daylight saving time in GetTime() and SetTime()
* handling of the gd register in function tracing on RISC-V
* disable U-Boot devices in ExitBootServices()

- Allow for log message continuation.
- Test fix, build time error checking for new categories

The log command has led to NULL dereferences if an unknown category name
name was used due to missing entries in the list of category names.

Add compile time checks for the array sizes of log_cat_name and
log_lvl_name to avoid future mishaps.

U-Boot Driver Model is supposed to remove devices with either
DM_REMOVE_ACTIVE_DMA or DM_REMOVE_OS_PREPARE flags set, before exiting.
Our bootm command does that by explicitly calling calling
"dm_remove_devices_flags(DM_REMOVE_ACTIVE_ALL);" and we also disable any
USB devices.

The EFI equivalent is doing none of those at the moment. As a result
probing an fTPM driver now renders it unusable in Linux. During our
(*probe) callback we open a session with OP-TEE, which is supposed to
close with our (*remove) callback. Since the (*remove) is never called,
once we boot into Linux and try to probe the device again we are getting
a busy error response. Moreover all uclass (*preremove) functions won't
run.

So let's fix this by mimicking what bootm does and disconnect devices
when efi_exit_boot_services() is called.

An UEFI application may change the value of the register that gd lives in.
But some of our functions like get_ticks() access this register. So we
have to set the gd register to the U-Boot value when entering a trace
point and set it back to the application value when exiting the trace
point.

On a board without hardware clock this software real time clock can be
used. The build time is used to initialize the RTC. So you will have
to adjust the time either manually using the 'date' command  or use
the 'sntp' to update the RTC with the time from a network time server.
See CONFIG_CMD_SNTP and CONFIG_BOOTP_NTPSERVER. The RTC time is
advanced according to CPU ticks.

Reviewed-by: NSimon Glass <sjg@chromium.org>

Some drivers use macro pr_cont() for continuing a message sent via printk.
Hence if we want to convert printk messaging to using the logging system,
we must support continuation of log messages too.

As pr_cont() does not provide a message level we need a means of
remembering the last log level.

With the patch a pseudo log level LOGL_CONT as well as a pseudo log
category LOGC_CONT are introduced. Using these results in the application
of the same log level and category as in the previous log message.

IPI code. Move the timer portions in with the other timer drivers. The
KConfig is not moved, since it also enables IPIs. It could also be split

It is unsafe to enable OF_BOARD_FIXUP only based on OF_SEPARATE.
OF_SEPARATE may indicate that the user wishes U-Boot to use a different
device tree than one obtained via OF_PRIOR_STAGE. However, OF_SEPARATE may
also indicate that the device tree which would be obtained via
OF_PRIOR_STAGE is invalid, nonexistant, or otherwise unusable. In this
latter case, enabling OF_BOARD_FIXUP will result in corruption of the
device tree. To remedy this, only enable OF_BOARD_FIXUP if U-Boot is
configured for S-Mode.
