- Add a comment about the MADT table version
- Add SPCR
- Update comment to include tables defined or reserved by ACPI
- Separate out the log newline
- Update comment in acpi_inc_align() to show the alignment
- Put back cast on table_compute_checksum()

- Split out hid-over-i2c into its own patch
- Drop mention of PRIC
- Rename acpi,desc to acpi,ddn
- Correct description of acpi,probed
- Drop hid-descr-addr
- Just add the device.txt binding file in this patch
- Change the example to ELAN
- Add a pointer to information about acpi,compatible
- Add new patch to move acpi_s3.h to include/acpi/
- Update commit message to say that we move most of its contents
- Move acpi_table.h to include/acpi
- Add forward declarations for the functions
- Fix file comment for acpi_table.c
- Fix a few typos
- Make use of BIT()
- Fix DMA_ typo
- Add missing error check in acpi_create_dmar()
- Drop duplicate assert
- Drop ASL_REVISION
- Add new patch to add hexdump.h to the unit test header
- Rename acpi_align_large() to acpi_align64()
- Fix 'RSDP' typo
- Fix 'XDST' typo
- Move acpi_align_large() out of dm_test_acpi_setup_base_tables()
- Beef up the comment explaining how the unaligned address is used

Changes in v2:
- Don't bracket the definitions with DM_SPI
- Add trailing commas to enum
- Drop the other comment change since it is already applied
- Drop the Chrome OS pieces
- Rename the 'coreboot' console to 'U-Boot'
- Move LOGC_ACPI definition to this patch
- Fix definition of HID
- Infer hid-over-i2c CID value
- Add the hid-over-i2c binding document

There are quite a few string functions in U-Boot with no tests. Make a
start by adding a test for strtoul().

Add a helper function for this operation. Update the strtoul() tests to
check upper case as well.

Update FAT writing to use this new function.

Different CPUs may support different address widths, meaning the amount of
memory they can address. Add a property for this to the cpu_info struct.

With ACPI we need to describe the settings of the SPI bus. Add enums to
handle this.

At present the cr50 driver claims the locality and does not release it for
Linux. This causes problems. Fix this by tracking what is claimed, and
adding a 'remove' method.

At present the cleanup() method is called on every transfer. It should
only be called on failing transfers. Fix this and tidy up the error
handling a little.

  To: u-boot

With P2SB the initial BAR (base-address register) is set up by TPL and
this is used unchanged right through U-Boot.

At present the reading of this address is split between the ofdata() and
probe() methods. There are a few problems that are unique to the p2sb.
One is that its children need to call pcr_read32(), etc. which needs to
have the p2sb address correct. Also some of its children are pinctrl
devices and pinctrl is used when any device is probed. So p2sb really
needs to get its base address set up in ofdata_to_platdata(), before it is
probed.

Another point is that reading the p2sb BAR will not work if the p2sb is
hidden. The FSP-S seems to hide it, presumably to avoid confusing PCI
enumeration.

Reading ofdata in ofdata_to_platdata() is the correct place anyway, so
this is easy to fix.

Move the code into one place and use the early-regs property in all cases
for simplicity and to avoid needing to probe any PCI devices just to read
the BAR.

At present if reading a BAR returns 0xffffffff (e.g. the device is not
present) then the value is masked and a different value is returned.
This makes it harder to detect the problem when debugging.

Update the function to avoid masking in this case.

ACPI (Advanced Configuration and Power Interface) is a standard for
specifying information about a platform. It is a little like device
tree but the bindings are part of the specification and it supports an
interpreted bytecode language.

Driver model does not use ACPI for U-Boot's configuration, but it is
convenient to have it support generation of ACPI tables for passing to
Linux, etc.

As a starting point, add an optional set of ACPI operations to each
device. Initially only a single operation is available, to obtain the
ACPI name for the device. More operations are added later.

Enable ACPI for sandbox to ensure build coverage and so that we can add
tests.

+* HID over I2C Device-Tree bindings
+
+HID over I2C provides support for various Human Interface Devices over the
+I2C bus. These devices can be for example touchpads, keyboards, touch screens
+or sensors.
+
+The specification has been written by Microsoft and is currently available here:
+http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx
+
+If this binding is used, the kernel module i2c-hid will handle the communication
+with the device and the generic hid core layer will handle the protocol.
+
+Required properties:
+- compatible: must be "hid-over-i2c"
+- reg: i2c slave address
+- hid-descr-addr: HID descriptor address
+- interrupts: interrupt line
+
+Additional optional properties:
+
+Some devices may support additional optional properties to help with, e.g.,
+power sequencing. The following properties can be supported by one or more
+device-specific compatible properties, which should be used in addition to the
+"hid-over-i2c" string.
+
+- compatible:
+  * "wacom,w9013" (Wacom W9013 digitizer). Supports:
+    - vdd-supply (3.3V)
+    - vddl-supply (1.8V)
+    - post-power-on-delay-ms
+
+- vdd-supply: phandle of the regulator that provides the supply voltage.
+- post-power-on-delay-ms: time required by the device after enabling its regulators
+  or powering it on, before it is ready for communication.
+
+Example:
+
+	i2c-hid-dev at 2c {
+		compatible = "hid-over-i2c";
+		reg = <0x2c>;
+		hid-descr-addr = <0x0020>;
+		interrupt-parent = <&gpx3>;
+		interrupts = <3 2>;
+	};

Devices need to report various identifiers in the ACPI tables. Rather than
hard-coding these in drivers it is typically better to put them in the
device tree.

Add a binding file to describe this.

Signed-off-by: Simon Glass <sjg@chromium.org>

Changes in v4:
- Put 'interrupts-extended' property on one line
- Rename acpi-probed to linux,probed
- Note that linux,probed is an out-of-tree feature

Changes in v3:
- Drop mention of PRIC
- Rename acpi,desc to acpi,ddn
- Correct description of acpi,probed
- Drop hid-descr-addr
- Just add the device.txt binding file in this patch
- Change the example to ELAN
- Add a pointer to information about acpi,compatible

Changes in v2:
- Fix definition of HID
- Infer hid-over-i2c CID value
- Add the hid-over-i2c binding document

+Devices
+=======
+
+Device bindings are described by their own individual binding files.
+
+U-Boot provides for some optional properties which are documented here. See
+also hid-over-i2c.txt which describes HID devices. See also
+Documentation/firmware-guide/acpi/enumeration.rst in the Linux kernel for
+the acpi,compatible property.
+
+ - acpi,has-power-resource : (boolean) true if this device has a power resource.
+    This causes an ACPI PowerResource to be written containing the properties
+    provided by this binding, to describe how to handle powering the device up
+    and down using GPIOs
+ - acpi,compatible : compatible string to report
+ - acpi,ddn : Contains the string to use as the _DDN (DOS (Disk Operating
+    System) Device Name)
+ - acpi,hid : Contains the string to use as the HID (Hardware ID)
+    identifier _HID
+ - acpi,uid : _UID value for device
+ - linux,probed : Tells U-Boot to add 'linux,probed' to the ACPI tables so that
+    Linux will only load the driver if the device can be detected (e.g. on I2C
+    bus). Note that this is an out-of-tree Linux feature.
+
+
+Example
+-------
+
+elan_touchscreen: elan-touchscreen at 10 {
+	compatible = "i2c-chip";
+	reg = <0x10>;
+	acpi,hid = "ELAN0001";
+	acpi,ddn = "ELAN Touchscreen";
+	interrupts-extended = <&acpi_gpe GPIO_21_IRQ IRQ_TYPE_EDGE_FALLING>;
+	linux,probed;
+};

The ASL compiler cannot handle C structures and the like so needs some
sort of header guard around these.

We already have an __ASSEMBLY__ #define but it seems best to create a new
one for ACPI since the rules may be different.

Add the check to a few files that ACPI always includes.

Each ACPI table has its own version number. Add the version numbers in a
single function so we can keep them consistent and easily see what
versions are supported.

Start a new acpi_table file in a generic directory to house this function.
We can move things over to this file from x86 as needed.

remapping.

Add a version simple version of this table with only the minimum fields
filled out. i.e. no entries.

Since ut_asserteq_mem() uses bin2hex() we should include this header in

Add a method to permit this.

The current code uses an address but a pointer would result in fewer
casts. Also it repeats the alignment code in a lot of places so this would
be better done in a helper function.

Update write_acpi_tables() to make use of the new acpi_ctx structure,
adding a few helpers to clean things up.

Call the new core function to permit devices to write their own ACPI
tables. These tables will appear after all other tables.

We don't actually support tables without an XSDT so we can drop this dead
code.

Move this code to a generic location so that we can test it with sandbox.
This requires adding a few new fields to acpi_ctx, so drop the local
variables used in the original code.

Also use mapmem to avoid pointer-to-address casts which don't work on
sandbox.

its own function, along with acpi_fill_header(), so we can write a test
for this code.

Changes in v4:
- Put back cast on table_compute_checksum()

Changes in v3:
- Fix 'XDST' typo
- Move acpi_align_large() out of dm_test_acpi_setup_base_tables()
- Beef up the comment explaining how the unaligned address is used

Changes in v2: None

It is useful to dump ACPI tables in U-Boot to see what has been generated.
Add a command to handle this.

To allow the command to find the tables, add a position into the global
data.

Support subcommands to list and dump the tables.

Wouldn't we prefer size_t like in other string functions for len?

Why a special logic for -1? Just use SIZE_MAX when calling the function.

We shouldn't check len and *in twice in the loop.

Please, add a test for

str_to_upper("", SIZE_MAX) which your code is handling incorrectly. - You miss copying 0x00 here.

We should not use toupper() here. We have to consider the FAT charset defined by CONFIG_FAT_DEFAULT_CODEPAGE.

Inconsistent size representation in the comment: 256 bytes, 4096 bytes?
Also I would rather name unused1 and unused2.

I didn't get the division. What proprietary means? For example NHLT spec is
public now AFAIK. But SPCR, for instance, is an extension by Microsoft.

Perhaps the division can be
1st group: ACPI spec defined
2nd: PCI SIG defined
3rd: UEFI ACPI extensions

?

Comma at the end, if it is a terminator line, is redundant.

This seems silly. Let's just have them in alpha order.

I think I did the best I could based on the feedback I got. If
something needs to be changed let's talk about it on the individual
patches.

This is an open TODO. We have capitalization.h which contains the relevant codepoints, e.g. in CP437_CAPITALIZATION_TABLE.
