Using the internal vs. external pull resistors it is possible to get
27 different combinations from 3 strapping pins. Add an implementation
of this.
This involves updating the sandbox GPIO driver to model external and
(weaker) internal pull resistors. The get_value() method now takes account
of what is driving a pin:
sandbox: GPIOD_EXT_DRIVEN - in which case GPIO_EXT_HIGH provides the
value
outside source - in which case GPIO_EXT_PULL_UP/DOWN indicates the
external state and we work the final state using those flags and
the internal GPIOD_PULL_UP/DOWN flags
Of course the outside source does not really exist in sandbox. We are just
modelling it for test purpose.
Signed-off-by: Simon Glass <sjg@chromium.org>
Add a new flag to keep track of whether sandbox is driving the pin, or
whether it is expecting an input signal. If it is driving, then the value
of the pin is the value being driven (0 or 1). If not driving, then we
consider the value 0, since we don't currently handle things like pull-ups
yet.

Historically, the reset_cpu() function had an `addr` parameter which was
meant to pass in an address of the reset vector location, where the CPU
should reset to. This feature is no longer used anywhere in U-Boot as
all reset_cpu() implementations now ignore the passed value. Generic
code has been added which always calls reset_cpu() with `0` which means
this feature can no longer be used easily anyway.
Over time, many implementations seem to have "misunderstood" the
existence of this parameter as a way to customize/parameterize the reset
(e.g. COLD vs WARM resets). As this is not properly supported, the
code will almost always not do what it is intended to (because all
call-sites just call reset_cpu() with 0).
To avoid confusion and to clean up the codebase from unused left-overs
of the past, remove the `addr` parameter entirely. Code which intends
to support different kinds of resets should be rewritten as a sysreset
driver instead.

The __of_translate_address routine translates an address from the
device tree into a CPU physical address. A note in the description of
the routine explains that the crossing of any level with
since inherited from IBM. This does not happen for Texas Instruments, or
at least for the beaglebone device tree. Without this patch, in fact,
the translation into physical addresses of the registers contained in the
am33xx-clocks.dtsi nodes would not be possible. They all have a parent
with #size-cells = <0>.
The CONFIG_OF_TRANSLATE_ZERO_SIZE_CELLS symbol makes translation
possible even in the case of crossing levels with #size-cells = <0>.
The patch acts conservatively on address translation, except for
removing a check within the of_translate_one function in the
drivers/core/of_addr.c file:
+
ranges = of_get_property(parent, rprop, &rlen);
- if (ranges == NULL && !of_empty_ranges_quirk(parent)) {
- debug("no ranges; cannot translate\n");
- return 1;
- }
if (ranges == NULL || rlen == 0) {
offset = of_read_number(addr, na);
memset(addr, 0, pna * 4);
debug("empty ranges; 1:1 translation\n");
There are two reasons:
1 The function of_empty_ranges_quirk always returns false, invalidating
the following if statement in case of null ranges. Therefore one of
the two checks is useless.
2 The implementation of the of_translate_one function found in the
common/fdt_support.c file has removed this check while keeping the one
about the 1:1 translation.
The patch adds a test and modifies a check for the correctness of an
address in the case of enabling translation also for zero size cells.
The added test checks translations of addresses generated by nodes of
a device tree similar to those you can find in the files am33xx.dtsi
and am33xx-clocks.dtsi for which the patch was created.
The patch was also tested on a beaglebone black board. The addresses
generated for the registers of the loaded drivers are those specified
by the AM335x reference manual.

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.

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.

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'.

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

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

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.

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

At present driver model supports the IRQ uclass but there is no way to

Add a mechanism, similar to clock and reset, to read the interrupts

U-Boot itself does not have interrupt-driven handlers, so just provide a

peripherals which must use an interrupt to determine when data is
available, for example.

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

[bmeng: correct the unclear comments in test.dts]
Signed-off-by: Bin Meng <bmeng.cn@gmail.com>
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.

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

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)

However this arrange cannot handle one important case, which is where a
