* Make size of UEFI variable store configurable.
* Add man pages for commands 'bootefi' and 'button'.
The linker script uses alphabetic sorting to group the different linker
lists together. Each group has its own struct and potentially its own
alignment. But when the linker packs the structs together it cannot ensure
that a linker list starts on the expected alignment boundary.
For example, if the first list has a struct size of 8 and we place 3 of
them in the image, that means that the next struct will start at offset
0x18 from the start of the linker_list section. If the next struct has
a size of 16 then it will start at an 8-byte aligned offset, but not a
16-byte aligned offset.
With sandbox on x86_64, a reference to a linker list item using
ll_entry_get() can force alignment of that particular linker_list item,
if it is in the same file as the linker_list item is declared.
Consider this example, where struct driver is 0x80 bytes:
ll_entry_declare(struct driver, fred, driver)
...
void *p = ll_entry_get(struct driver, fred, driver)
If these two lines of code are in the same file, then the entry is forced
to be aligned at the 'struct driver' alignment, which is 16 bytes. If the
second line of code is in a different file, then no action is taken, since
the compiler cannot update the alignment of the linker_list item.
In the first case, an 8-byte 'fill' region is added:
.u_boot_list_2_driver_2_testbus_drv
0x0000000000270018 0x80 test/built-in.o
0x0000000000270018 _u_boot_list_2_driver_2_testbus_drv
.u_boot_list_2_driver_2_testfdt1_drv
0x0000000000270098 0x80 test/built-in.o
0x0000000000270098 _u_boot_list_2_driver_2_testfdt1_drv
*fill* 0x0000000000270118 0x8
.u_boot_list_2_driver_2_testfdt_drv
0x0000000000270120 0x80 test/built-in.o
0x0000000000270120 _u_boot_list_2_driver_2_testfdt_drv
.u_boot_list_2_driver_2_testprobe_drv
0x00000000002701a0 0x80 test/built-in.o
0x00000000002701a0 _u_boot_list_2_driver_2_testprobe_drv
With this, the linker_list no-longer works since items after testfdt1_drv
are not at the expected address.
Ideally we would have a way to tell gcc not to align structs in this way.
It is not clear how we could do this, and in any case it would require us
to adjust every struct used by the linker_list feature.
One possible fix is to force each separate linker_list to start on the
largest possible boundary that can be required by the compiler. However
that does not seem to work on x86_64, which uses 16-byte alignment in this
case but needs 32-byte alignment.
So add a Kconfig option to handle this. Set the default value to 4 so
as to avoid changing platforms that don't need it.
Update the ll_entry_start() accordingly.

This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.
In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.
The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.
Rename everything accordingly.
Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in

Some commands can get very unweildy if they have too many positional
arguments. Adding options makes them easier to read, remember, and
understand.
This implementation of getopt has been taken from barebox, which has had
option support for quite a while. I have made a few modifications to their
version, such as the removal of opterr in favor of a separate getopt_silent
function. In addition, I have moved all global variables into struct
getopt_context.
The getopt from barebox also re-orders the arguments passed to it so that
non-options are placed last. This allows users to specify options anywhere.
For example, `ls -l foo/ -R` would be re-ordered to `ls -l -R foo/` as
getopt parsed the options. However, this feature conflicts with the const
argv in cmd_tbl->cmd. This was originally added in 54841ab50c ("Make sure
that argv[] argument pointers are not modified."). The reason stated in
that commit is that hush requires argv to stay unmodified. Has this
situation changed? Barebox also uses hush, and does not have this problem.
Perhaps we could use their fix?
I have assigned maintenance of getopt to Simon Glass, as it is currently
only used by the log command. I would also be fine maintaining it.

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.

SPL is creating fit-images DT node when loadables are recorded in selected
configuration. Entries which are created are using entry-point and
load-addr property names. But there shouldn't be a need to use non standard
properties because entry/load are standard FIT properties. But using
standard FIT properties enables option to use generic FIT functions to
descrease SPL size. Here is result for ZynqMP virt configuration:
xilinx_zynqmp_virt: spl/u-boot-spl:all -82 spl/u-boot-spl:rodata -22 spl/u-boot-spl:text -60
The patch causes change in run time fit image record.
Before:
fit-images {
uboot {
os = "u-boot";
type = "firmware";
size = <0xfd520>;
entry-point = <0x8000000>;
load-addr = <0x8000000>;
};
};
After:
fit-images {
uboot {
os = "u-boot";
type = "firmware";
size = <0xfd520>;
entry = <0x8000000>;
load = <0x8000000>;
};
};
Replacing calling fdt_getprop_u32() by fit_image_get_entry/load() also
enables support for reading entry/load properties recorded in 64bit format.

At present if CONFIG_LOG enabled, putting LOG_DEBUG at the top of a file
(before log.h inclusion) causes _log() to be executed for every log()
call, regardless of the build- or run-time logging level.
However there is no guarantee that the log record will actually be
displayed. If the current log level is lower than LOGL_DEBUG then it will
not be.
Add a way to signal that the log record should always be displayed and
update log_passes_filters() to handle this.
With the new behaviour, log_debug() will always log if LOG_DEBUG is
enabled.
Move log_test_syslog_nodebug() into its own file since it cannot be made
to work where it is, with LOG_DEBUG defined.

The Fully-Programmable Input/Output Array (FPIOA) device controls pin
multiplexing on the K210. The FPIOA can remap any supported function to any
multifunctional IO pin. It can also perform basic GPIO functions, such as
reading the current value of a pin. However, GPIO functionality remains
largely unimplemented (in favor of the dedicated GPIO peripherals).

The pinmux property allows for smaller and more compact device trees,
especially when there are many pins which need to be assigned individually.
Instead of specifying an array of strings to be parsed as pins and a
function property, the pinmux property contains an array of integers
representing pinmux groups. A pinmux group consists of the pin identifier
and mux settings represented as a single integer or an array of integers.
Each individual pin controller driver specifies the exact format of a
pinmux group. As specified in the Linux documentation, a pinmux group may
be multiple integers long. However, no existing drivers use multi-integer
pinmux groups, so I have chosen to omit this feature. This makes the
implementation easier, since there is no need to allocate a buffer to do
endian conversions.
Support for the pinmux property is done differently than in Linux. As far
as I can tell, inversion of control is used when implementing support for
the pins and groups properties to avoid allocating. This results in some
duplication of effort; every property in a config node is parsed once for
each pin in that node. This is not such an overhead with pins and groups
properties, since having multiple pins in one config node does not occur
especially often. However, the semantics of the pinmux property make such a
configuration much more appealing. A future patch could parse all config
properties at once and store them in an array. This would make it easier to
create drivers which do not function solely as callbacks from
pinctrl-generic.
This commit increases the size of the sandbox build by approximately 48
bytes. However, it also decreases the size of the K210 device tree by 2
KiB from the previous version of this series.
The documentation has been updated from the last Linux commit before it was
split off into yaml files.

The VIM3 on-board MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.
This adds this dynamic switching right before booting Linux
