c61479bbd8 Cr50: Added Pinweaver base implementation.
This adds some of the ground work for hardware backed brute force
resistance on Cr50. The feature is called Pinweaver. It will
initially be used to enable PIN authentication on CrOS devices
without reducing the security of the platform. A Merkle tree is
used to validate encrypted metadata used to track login attempts.

The metadata tracks counts of failed attempts, a timestamp of the
last failed attempt, the secrets, and any associated parameters.
Instead of storing the metadata on Cr50 an AES-CTR is used with an
HMAC to encrypt the data so it can be stored off-chip and loaded
when needed.

The Merkle tree is used to track the current state of all the
metadata to prevent replay attacks of previously exported copies.
It is a tree of hashes whose root hash is stored on Cr50, and whose
leaves are the HMACs of the encrypted metadata.

e54c3e1728 chipset: Add callback for chipset pre-initialization
This change adds a callback for chipset_pre_init_callback which is
made by x86 common power state machine when in G3S5 state. Until now,
there was a hook CHIPSET_PRE_INIT_CALLBACK that was notified by
chipset task when in G3S5 state. However, there are at least following
reasons why this should be a callback and not a hook notification:
1. The initialization that is done as part of pre-init could be
essential for the power state machine to make progress. Though the
chipset task goes to sleep waiting for power signals after the hook
notification, pre-initialization can all be done as part of a callback
since it is mostly board-specific code that is doing work to
initialize PMIC.
2. Typically, boards use I2C transactions to setup PMIC on getting
chipset pre-init notification. However, since i2c transfers are not
encouraged in hook task, they have to be deferred anyways.
3. Since the initialization is being done as part of hook task, use of
any constructs e.g. pwr_5v_en_req which allows multiple consumers to
enable/disable power rails will use task id for hook task. Instead it
is better to provide correct information about the task by letting
chipset task perform this request.

Thus, this change adds a callback chipset_pre_init_callback in G3S5
state for x86 power state machine. This callback is guarded by
CONFIG_CHIPSET_HAS_PRE_INIT_CALLBACK.

The hook notification is left as is for now until all x86 boards are
moved over to using the newly added callback.

46ca9738f2 chgstv2: Check charger power in prevent_power_on.
charge_prevent_power_on() had sections which were gated on the following
CONFIG_* option:

    CONFIG_CHARGER_LIMIT_POWER_THRESH_BAT_PCT

However, the block of code that this gated didn't even take the battery
percentage into account and made it very confusing as to why.

This commit simply changes the CONFIG_* option used to gate to be the
following:

    CONFIG_CHARGER_MIN_POWER_MW_FOR_POWER_ON

This better reflects the checks that were actually being made.

Additionally, this CONFIG_* option is defined by default for boards that
have a chipset task and is initialized to 15W, which is the power that
indicates that the charger is likely to speak USB PD.

b42dd73603 core: add chip-specific memory regions definition mechanism
When a chip has special/non-contiguous SRAM physical memory region,
rather than extending the generic linker file ad nauseam, define a
mechanism to declare a chip specific list of those regions.

To do so, a chip must declare the CONFIG_CHIP_MEMORY_REGIONS
configuration and have a memory_regions.inc with the list of regions.

The special-purpose preprocessed chip/<chip_name>/memory_regions.inc
file has one region declaration per line using the following macro:
REGION(name, attributes, start_address, size)

Each region will get a proper MEMORY entry and a section in the linker
file.
the __SECTION(region_name) helper is provided as a convenience to
declare variable in a specific region.

Note: those 'special' regions are NOT cleared at startup contrary to
.bss.

f23f45e74e cortex-m: enable I-cache on ARMv7-M
The ARMv7-M ISA defines standard (and optional) mechanism to manage the
CPU caches through the SCB (System Control Block) registers.
So far, only the Cortex-M7 core implements such as a mechanism (e.g. the
Cortex-M4 with caches we have are using a proprietary mechanism for the
management).

Define the functions to use the I-Cache,
and enable them on STM32H7 which is our only supported Cortex-M7 core.

The D-Cache mechanism is still To Be Done, as it involves a bit more

d940d2a991 common: Add support for PWM LEDs.
This commit adds support for a common framework for PWM controlled LEDs.
If there are multiple LEDs, they will all follow the same pattern.  The
pattern is such that it follows the Chrome OS LED behaviour
specification, essentially a similar version of led_policy_std.c but for
PWM controlled LEDs.

To use this framework, a board must do the following:

- First, define the number of logical PWM LEDs which will be controlled
  by this common policy, CONFIG_LED_PWM_COUNT.

- Then declare those logical LEDs and define the PWM channels that
 comprise those LEDs. (struct pwm_led pwm_leds[]).

- Next, define what each color should look like (struct pwm_led
  led_color_map[]).

By default, the colors follow the recommended colors in the LED
behaviour spec, which assume an LED with a red and green channel.  If a
board differs or wishes to change the colors in general, they can
redefine the colors (CONFIG_LED_PWM_*_COLOR) as they see fit.  The
colors must be one in enum ec_led_colors.  These colors are the ones
that can represent the charging state, SoC state, etc.

b245e71e82 stm32: add usb_isochronous
Templates for USB isochronous implementation.  Current implementation
only supports TX transmit.  Example of usage can be found in CL:803414.

Basically, declare an USB isochronous interface by

USB_ISOCHRONOUS_CONFIG_FULL(<NAME>,
                            <INTERFACE_NUM>,
                            <USB_CLASS>,
                            <USB_SUBCLASS>,
                            <SUB_PROTOCOL>,
                            <USB_STR_FOR_INTERFACE_NAME>,
                            <USB_EP_NUM>,
                            <PACKET_SIZE>,

                            <SET_INTERFACE>)

where <PACKET_SIZE> is size of each USB packet, <TX_CALLBACK> is called
when USB hardware has completed a packet.  The buffer that USB is not
currently using will be passed to <TX_CALLBACK>, allow applications to
write next packet to it.

When a SET_INTERFACE packet is received, <SET_INTERFACE> will be called
with bAlternateSetting and bInterfaceNumber.

We will declare interface descriptor with bAlternateSetting = 0 and 1
for you, if you need more alternate settings, you need to declare by
yourself.

51e9e69f38 power: introducing pwr_avg console command
pwr_avg provides an average voltage, current, and power over the last
1 minute. It's up to the battery drivers to implement this
functionality.
This change allows us to have better power tracking while minimizing
the power impact on the EC, because
- the pwr_avg command only needs to be called once every minute, and is
short, thus less expensive to parse on ECs without a UART buffer
- the work done to keep the avg is partially done by the batteries
already and it's just a question of retrieving it.
