7f0f1806e3 test: pinmux: Add test for pin muxing
This extends the pinctrl-sandbox driver to support pin muxing, and adds a
test for that behaviour. The test is done in C and not python (like the
existing tests for the pinctrl uclass) because it needs to call
pinctrl_select_state.  Another option could be to add a command that
invokes pinctrl_select_state and then test everything in
test/py/tests/test_pinmux.py.

The pinctrl-sandbox driver now mimics the way that many pinmux devices
work.  There are two groups of pins which are muxed together, as well as
four pins which are muxed individually. I have tried to test all normal
paths. However, very few error cases are explicitly checked for.

175e8322bc sandbox: avoid duplicate backslash input
When using SDL for input the SDL key codes are first converted to Linux key
codes and then to matrix entries of the cross wired keyboard.

We must not map any key code to two different places on the keyboard. So
comment out one backslash position.

Update the rest of the file from Linux 5.7.

358599efd8 firmware: add SCMI agent uclass
This change introduces SCMI agent uclass to interact with a firmware
using the SCMI protocols [1].

SCMI agent uclass currently supports a single method to request
processing of the SCMI message by an identified server. A SCMI message
is made of a byte payload associated to a protocol ID and a message ID,
all defined by the SCMI specification [1]. On return from process_msg()
method, the caller gets the service response.

SCMI agent uclass defines a post bind generic sequence for all devices.
The sequence binds all the SCMI protocols listed in the FDT for that
SCMI agent device. Currently none, but later change will introduce
protocols.

This change implements a simple sandbox device for the SCMI agent uclass.
The sandbox nicely answers SCMI_NOT_SUPPORTED to SCMI messages.
To prepare for further test support, the sandbox exposes a architecture
function for test application to read the sandbox emulated devices state.
Currently supports 2 SCMI agents, identified by an ID in the FDT device
name. The simplistic DM test does nothing yet.

SCMI agent uclass is designed for platforms that embed a SCMI server in
a firmware hosted somewhere, for example in a companion co-processor or
in the secure world of the executing processor. SCMI protocols allow an
SCMI agent to discover and access external resources as clock, reset
controllers and more. SCMI agent and server communicate following the
SCMI specification [1]. This SCMI agent implementation complies with
the DT bindings defined in the Linux kernel source tree regarding
SCMI agent description since v5.8.

a402035028 sandbox: u-boot.lds: Remove bogus __bss_start symbol
The sections described in the sandbox linker script are inserted before
data section via "INSERT BEFORE .data;". Running readelf -S on sandbox
u-boot binary shows that the bss section is located after the data

This means that the __bss_start assignment in the linker script is bogus,
as the actual bss section start is located elsewhere. Remove this
assignment, as the __bss_start symbol is not used on sandbox anyway.

037a56d6b1 sandbox, test: change hog gpio
Since commit 9ba84329dc ("sandbox, test: add test for GPIO_HOG
function"), the gpio_a 0,1,2 and 3 are used by hog in test.dts.
But 2 leds 'sandbox:red' and 'sandbox:green' are using gpio_a 0
and 1. As hog always request his gpios, the led command on both
led is broken:

=> led sandbox:red
LED 'sandbox:red' not found (err=-16)

The gpio is already requested by hog, so it can't be enabled
for led 'sandbox:red'.

This commit change the gpio used by hog to 10, 11, 12 and 13,
so the led command could be used again with 'sandbox:red' and
'sandbox:green'.

fefac0b064 dm: acpi: Enhance acpi_get_name()
For many device types it is possible to figure out the name just by
looking at its uclass or parent. Add a function to handle this, since it
allows us to cover the vast majority of cases automatically.

However it is sometimes impossible to figure out an ACPI name for a device
just by looking at its uclass. For example a touch device may have a
vendor-specific name. Add a new "acpi,name" property to allow a custom
name to be created.

With this new feature we can drop the get_name() methods in the sandbox
I2C and SPI drivers. They were only added for testing purposes. Update the
tests to use the new values.

be1a6e9425 dm: uclass: don't assign aliased seq numbers
If there are aliases for an uclass, set the base for the "dynamically"
allocated numbers next to the highest alias.

Please note, that this might lead to holes in the sequences, depending
on the device tree. For example if there is only an alias "ethernet1",
the next device seq number would be 2.

In particular this fixes a problem with boards which are using ethernet
aliases but also might have network add-in cards like the E1000. If the
board is started with the add-in card and depending on the order of the
drivers, the E1000 might occupy the first ethernet device and mess up
all the hardware addresses, because the devices are now shifted by one.

Also adapt the test cases to the new handling and add test cases
checking the holes in the seq numbers.

2960107a22 sandbox: also restore terminal settings when killed by SIGINT
Hitting Ctrl-C is a documented way to exit the sandbox, but it is not
actually equivalent to the reset command. The latter, since it follows
normal process exit, takes care to reset terminal settings and
restoring the O_NONBLOCK behaviour of stdin (and, in a terminal, that
is usually the same file description as stdout and stderr, i.e. some
/dev/pts/NN).

Failure to restore (remove) O_NONBLOCK from stdout/stderr can cause
very surprising and hard to debug problems back in the terminal. For
example, I had "make -j8" consistently failing without much
information about just exactly what went wrong, but sometimes I did
get a "echo: write error". I was at first afraid my disk was getting
bad, but then a simple "dmesg" _also_ failed with write error - so it
was writing to the terminal that was buggered. And both "make -j8" and
dmesg in another terminal window worked just fine.

So install a SIGINT handler so that if the chosen terminal
mode (cooked or raw-with-sigs) means Ctrl-C sends a SIGINT, we will
still call os_fd_restore(), then reraise the signal and die as usual
from SIGINT.

Before:

$ grep flags /proc/$$/fdinfo/1
flags:  0102002
$ ./u-boot
# hit Ctrl-C
$ grep flags /proc/$$/fdinfo/1
flags:  0106002

After:

$ grep flags /proc/$$/fdinfo/1
flags:  0102002
$ ./u-boot
# hit Ctrl-C
$ grep flags /proc/$$/fdinfo/1
flags:  0102002

025543554c dm: irq: Add support for requesting interrupts
At present driver model supports the IRQ uclass but there is no way to
request a particular interrupt for a driver.

Add a mechanism, similar to clock and reset, to read the interrupts
required by a device from the device tree and to request those interrupts.

U-Boot itself does not have interrupt-driven handlers, so just provide a
means to read and clear an interrupt. This can be useful to handle
peripherals which must use an interrupt to determine when data is
available, for example.

Bring over the basic binding file as well, from Linux v5.4. Note that the
older binding is not supported in U-Boot; the newer 'special form' must be
used.

Add a simple test of the new functionality.

ba87607971 dm: irq: Add support for interrupt controller types
There can be different types of interrupt controllers in a system and some
drivers may need to distinguish between these. In general this can be
handled using the device tree by adding the interrupt information to
device nodes.

However on x86 devices we have interrupt controllers which are not tied
to any particular device and not really used in U-Boot. These still need
to be inited, so a convenient method is to give each controller a type
and allow a particular controller type to be probed.

Add support for this in sandbox along with a test.

These functions do not use driver model but are fairly widely used in

so we don't want to label them as 'legacy'.

Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

073e6d65d1 sandbox: fix cpu property in test.dts for pytest
When I tried to run some new efi tests with pytest, efi_smbios_register()
triggered a segmentation fault. Here is the location where it happened:
efi_init_obj_list()
  efi_smbios_register()
    write_smbios_table()
      smbios_write_type4()
        smbios_write_type4_dm()

where dev_get_parent_platdata() should return a pointer to struct
cpu_platdata, but it is actually NULL because any cpu device on
sandbox is attached to "root_driver."

With this patch, this issue will be fixed by moving all the definitions
of cpus under "cpus" node so that they have a "cpu_bus" parent.

9b69ba4a78 pci: sandbox: Move the emulators into their own node
Sandbox pci works using emulation drivers which are currently children of
the pci device:

	pci-controller {
		pci@1f,0 {
			compatible = "pci-generic";
			reg = <0xf800 0 0 0 0>;
			emul@1f,0 {
				compatible = "sandbox,swap-case";
			};
		};
	};

In this case the emulation device is attached to pci device on address
f800 (device 1f, function 0) and provides the swap-case functionality.

However this is not ideal, since every device on a PCI bus has a child
device. This is only really the case for sandbox, but we want to avoid
special-case code for sandbox.

Worse, child devices cannot be probed before their parents. This forces
us to use 'find' rather than 'get' to obtain the emulator device. In fact
the emulator devices are never probed. There is code in
sandbox_pci_emul_post_probe() which tries to track when emulators are
active, but at present this does not work.

A better approach seems to be to add a separate node elsewhere in the
device tree, an 'emulation parent'. This could be given a bogus address
(such as -1) to hide the emulators away from the 'pci' command, but it
seems better to keep it at the root node to avoid such hacks.

Then we can use a phandle to point from the device to the correct
emulator, and only on sandbox. The code to find an emulator does not
interfere with normal pci operation.

Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator
given a bus, and finding a bus given an emulator. Update the existing
device trees and the code for finding an emulator.

This brings PCI emulators more into line with I2C.

4a6409b74c sandbox: Correct maths in allocation routines
Allocation routines were adjusted to ensure that the returned addresses
are a multiple of the page size, but the header code was not updated to
take account of this. These routines assume that the header size is the
same as the page size which is unlikely.

At present os_realloc() does not work correctly due to this bug. The only
user is the hostfs 'ls' command, and only if the directory contains a
unusually long filename, which likely explains why this bug was not
caught earlier.

Fix this by doing the calculations using the obtained page size.

001d1885f0 sandbox: Improve debugging in initcall_run_list()
At present if one of the initcalls fails on sandbox the address printing
is not help, e.g.:

  initcall sequence 0000557678967c80 failed at call 00005576709dfe1f (err=-96)

This is because U-Boot gets relocated high into memory and the relocation
offset (gd->reloc_off) does not work correctly for sandbox.

Add support for finding the base address of the text region (at least on
Linux) and use that to set the relocation offset. This makes the output
better:

  initcall sequence 0000560775957c80 failed at call 0000000000048134 (err=-96)

Then you use can use grep to see which init call failed, e.g.:

   $ grep 0000000000048134 u-boot.map
   stdio_add_devices

Of course another option is to run it with a debugger such as gdb:

   $ gdb u-boot
   ...
   (gdb) br initcall.h:41
   Breakpoint 1 at 0x4db9d: initcall.h:41. (2 locations)

Note that two locations are reported, since this function is used in both
board_init_f() and board_init_r().

When fixing sandbox test for regmap_read_poll_timeout(), the

thus generating warnings when used out of sandbox :

include/regmap.h:277:4: warning: implicit declaration of function 'sandbox_timer_add_offset' [-Wimplicit-function-declaration]

This fix adds a timer_test_add_offset() only defined in sandbox, and
renames the previous sandbox_timer_add_offset() to it.

ffd4c7c2ec dts: switch spi-flash to jedec, spi-nor compatible
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot
dts files. This compatible has been added in sf_probe, let use it.

This patch switches to jedec,spi-nor when spi-flash is used in the DTS
and DTSI files, and removed spi-flash when jedec,spi-nor is already
present.

The x86 dts are switched in a separate commit since it depends on a change

1c5a81d803 sandbox: Remove the old memory file later
When debugging sandbox it is sometimes annoying that the memory file is
deleted early on. If sandbox later crashes or we quit (using the
debugger), it is not possible to run it again with the same state since
the memory file is gone.

Remove the old memory file when sandbox exits, instead. Also add debugging
showing the memory filename.

3fcb714758 sandbox: Fix setjmp/longjmp
In sandbox, longjmp returns to itself in an endless loop because
os_longjmp() calls into longjmp() which is provided by U-Boot which
again calls os_longjmp().

Setjmp on the other hand must not return because otherwise the
return freees up stack elements that we need during longjmp().

The only straight forward fix that doesn't involve nasty hacks I
could find is to directly link against the system setjmp/longjmp
implementations. That means we just provide the compiler with
hints that the symbol will be available and actually fill them
out with versions from libc.

This approach should be reasonably platform agnostic

428aa0ca56 sandbox: Enhance map_to_sysmem() to handle foreign pointers
At present map_sysmem() maps an address into the sandbox RAM buffer,
return a pointer, while map_to_sysmem() goes the other way.

The mapping is currently just 1:1 since a case was not found where a more
flexible mapping was needed. PCI does have a separate and more complex
mapping, but uses its own mechanism.

However this arrange cannot handle one important case, which is where a
test declares a stack variable and passes a pointer to it into a U-Boot
function which uses map_to_sysmem() to turn it into a address. Since the
pointer is not inside emulated DRAM, this will fail.

Add a mapping feature which can handle any such pointer, mapping it to a
simple tag value which can be passed around in U-Boot as an address.

7e21fbca26 efi_loader: Rename sections to allow for implicit data
Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.

In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".

Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.

With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

'fdt_dummy0', 'fdt_dummy1', 'fdt_dummy2', 'fdt_dummy3' properties.

Similar DTC warnings have been recently fixed in Linux kernel, e.g. via
v4.17-rc1 commit d366c30d19f4 ("ARM: dts: STi: Fix aliases property name
for STi boards").

If done alone, the DTS update generates a failure of the
`ut dm fdt_translation` unit test in sandbox environment as seen below:

$ ./u-boot -d arch/sandbox/dts/test.dtb
---<-snip->---
=> ut dm fdt_translation
Test: dm_test_fdt_translation: test-fdt.c
test/dm/test-fdt.c:444, dm_test_fdt_translation(): 0 == uclass_find_device_by_seq(UCLASS_TEST_DUMMY, 0, 1, &dev): Expected 0, got -19

Failures: 2
---<-snip->---

Fix this issue in place, by updating the "name" string in the
UCLASS_DRIVER(fdt_dummy) definition, so that it matches the newly
updated aliases properties. After that, the test passes:

$ ./u-boot -d arch/sandbox/dts/test.dtb

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

e8d5291824 core: ofnode: Fix translation for #size-cells == 0
Commit 286ede6 ("drivers: core: Add translation in live tree case") made
dev_get_addr always use proper bus translations for addresses read from
the device tree. But this leads to problems with certain busses, e.g.
I2C busses, which run into an error during translation, and hence stop
working.

It turns out that of_translate_address() and fdt_translate_address()
stop the address translation with an error when they're asked to
translate addresses for busses where #size-cells == 0 (comment from
drivers/core/of_addr.c):

 * Note: We consider that crossing any level with #size-cells == 0 to mean
 * that translation is impossible (that is we are not dealing with a value
 * that can be mapped to a cpu physical address). This is not really specified
 * that way, but this is traditionally the way IBM at least do things

To fix this case, we check in both the live-tree and non-live tree-case,
whether the bus of the device whose address is about to be translated
has size-cell size zero. If this is the case, we just read the address
as a plain integer and return it, and only apply bus translations if the
size-cell size if greater than zero.

e48eeb9ea3 dm: blk: Improve block device claiming
The intention with block devices is that the device number (devnum field
in its descriptor) matches the alias of its parent device. For example,
with:

	aliases {
		mmc0 = "/sdhci@700b0600";
		mmc1 = "/sdhci@700b0400";
	}

we expect that the block devices for mmc0 and mmc1 would have device
numbers of 0 and 1 respectively.

Unfortunately this does not currently always happen. If there is another
MMC device earlier in the driver model data structures its block device
will be created first. It will therefore get device number 0 and mmc0
will therefore miss out. In this case the MMC device will have sequence
number 0 but its block device will not.

To avoid this, allow a device to request a device number and bump any
existing device number that is using it. This all happens during the
binding phase so it is safe to change these numbers around. This allows
device numbers to match the aliases in all circumstances.

Add a test to verify the behaviour.

63c0941726 libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY
Commit e2f88dfd2d ("libfdt: Introduce new ARCH_FIXUP_FDT option")
allows us to skip memory setup of DTB, but a problem for ARM is that
spin_table_update_dt() and psci_update_dt() are skipped as well if
CONFIG_ARCH_FIXUP_FDT is disabled.

This commit allows us to skip only fdt_fixup_memory_banks() instead
of the whole of arch_fixup_fdt().  It will be useful when we want to
use a memory node from a kernel DTB as is, but need some fixups for
Spin-Table/PSCI.

However this is annoying for tests, which may want to examine the state

be used to exit, if required.

135aa95002 clk: convert API to match reset/mailbox style
The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
  provider now implements a single set of clocks. This provides a simpler
  conceptual interface to clients, and better aligns with device tree
  clock bindings.
* Clocks are now identified with a single "struct clk", rather than
  requiring clients to store the clock provider device and clock identity
  values separately. For simple clock consumers, this isolates clients
  from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
  clk-uclass.h contains the provider API. This aligns with the recently
  added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
  can customize these operations if needed. This also aligns with the
  recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
  clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.

Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.

test/py passes for sandbox (which invokes the dm clk test amongst
others).

The current reset API implements a method to reset the entire system.
In the near future, I'd like to introduce code that implements the device
tree reset bindings; i.e. the equivalent of the Linux kernel's reset API.
This controls resets to individual HW blocks or external chips with reset
signals. It doesn't make sense to merge the two APIs into one since they
have different semantic purposes. Resolve the naming conflict by renaming
the existing reset API to sysreset instead, so the new reset API can be
called just reset.
