89bcc93547 stm32f0: flash: Don't check protect bits for flash that doesn't exist
Each pair of protect bits locks 4K, so for parts with 64K flash, don't
bother checking STM32_OPTB_WRP23.

BUG=chrome-os-partner:49354
TEST=Run flashrom to protect PD MCU (see repro steps on linked crbug),
reboot and verify system boots into dev mode with all_at_boot and

ebd29d4557 nuc: Adjust core clock from 16/12 MHz to 15/13 MHz.
We found the deviation of 115200 UART baud-rate is too large when core
clock is 16 or 12MHz. It causes failure during FAFT since sometime EC
could not receive correct commands to proceed test. We adjusted core
clock from 16/12 to 15/13 to reduce the deviation of 115200. Both of
them have run FAFT and stress tests for weeks and no UART issues were
found.

Since the lowest source clock of i2c is 6.5MHz, we modified tSCLL, tSCLH
and hold time directly for better i2c timing when freq is 400K. And if
freq is 100K, we introduced normal mode to handle it.

Modified sources:
1. clock.c: Adjust core clock from 16/12 MHz to 15/13 MHz.
2. clock_chip.h: Set target core clock as 15 MHz.
3. uart.c: Add baud-rate support for 15/13 MHz.
4. register.h: Add new register definitions of SMBus.
5. i2c.c: Modified tSCLL, tSCLH and hold time directly for better i2c
timing.

e933d0b7b6 mec1322: lpc: Clear STATUS_PROCESSING LPC status bit on init
When a sysjump host command is received, there is a (usually) small
period of time when the EC has sent a reply packet back to the host, but
interrupts are still enabled. If the host sends a new host command,
STATUS_PROCESSING will be set by the EC ISR, but the host command will
never be handled due to pending sysjump. In this case, STATUS_PROCESSING
will still be set, so we need to clear it on LPC post-sysjump re-init.

BUG=chrome-os-partner:49318
TEST=Add 200ms msleep before call to interrupt_disable() in
jump_to_image(), boot to software sync, and verify host commands are
handled successfully post-sysjump and system continues to boot.

Modified hibernate funcs to support hibernate_wake_pins on weatley, npcx_evb

a48945568e wheatley: Proposed workaround for RESET_FLAG_RESET_PIN issue on wheatley.
During pressing VolUp + VolDn + Pwr buttons, Silego polls down both EC_RST_L
and ROP_LDO_EN on wheatley. Beside VCC1_RST occurs, power-on reset also occurs
simultaneously since EC's power rail is turned off by PMIC for a while.
VCC1_RST_STS bit is cleared by power-on reset and it will influence recovery
mode detection.
The workaround treats no matter power-on or VCC1_RST reset as reset-pin reset.
Use BOARD_WHEATLEY to distinguish them.

f72decc804 Cr50: Implement USB according to Programmer's Guide
This is a rewrite of the Cr50 USB Device Control Endpoint
implementation, using the instructions in the DWC USB 2.0 OTG
Programmer's Guide (such as they are). Some of the major
differences:

* Not every USB interrupt indicates the receipt of an incoming
  packet. Many merely provide updates on packet transfer status,
  transaction stages, or other activity. We handle those
  cases correctly.

* We may need to start a new Control transaction at any point,
  even in the middle of an existing transaction.

* Large IN data transfers can be handled with one interrupt by
  chaining multiple together.

* Logical separation of the phases of each transaction (Setup,
  Data, Status).

That said, while this CL matches the Programmer's Guide fairly
closely, that Guide is pretty crappy and this is just the first
commit. There is still a fair amount to do (marked with comments
and bug reports). However, it works at least as well as the
previous version and is much closer to what the supplier claims
is the correct implementation.

30f8fdaa91 Cr50: Cleaner API for USB_DECLARE_IFACE callbacks
The control endpoint (EP0) can receive some Setup packets that
are specific to individual Interfaces. The USB_DECLARE_IFACE
macro is used to register the callbacks that an interface
implementation provides to handle those Setup packets.

This change cleans up the callback API a bit, so that we don't
have to export the internal workings of the Cr50's EP0 interrupt
handler.

55e5649494 cr50: fix calculations determining the image type
The startup message includes the type of the image it is running (RO
vs RW currently). cr50 reports RW as RO, which this patch fixes. This
issue requires a bit more attention though: first, the RO type can be
deduced at compile time. Second, RW and RW_B should be accommodated.
RW_B should also be accounted in other places in the code where now
only two options are considered: RO vs RW.

432ea75d92 cr50: add ability to include two identical RW sections in the EC image
A typical EC image includes two similar in their functionality
subsections, RO and RW. CR50 has a small RO subsection, all it does -
detects a proper RW image to run and starts it up. To provide for
reliable firmware updates, the CR50 image needs to include two RW
sections, while the code is running from one RW subsection, the other
one can be upgraded.

This patch adds the ability to generate two identical RW sections,
mapped half flash size apart, and include them into the resulting EC
image.

To keep things simple the previously existing RW section's name is not
being changed, while the new (identical) RW section is named RW_B.

Two configuration options need to be defined to enable building of the
new image type: CONFIG_RW_B to enable the feature and
CONFIG_RW_B_MEM_OFF to define where RW_B should be mapped into the
flash.

A new rule added to Makefile.rules allows to generate a different lds
file from the same source (core/cortex-m/ec.lds.S) by defining a
compile time variable to pick a different base address for the
rewritable section, when RW_B is built.

BUG=chromium:43025
TEST=as follows:
    - make buildall -j still succeeds

d1f1e7722d cr50: reduce hash implementation stack requirements
Stack space is pretty tight on cr50, and since there is no need to
support SHA digest sizes in excess of 256 bits, the digest buffer size
should be reduced.

This patch makes the maximum expected digest size dependent on the set
of configured hash algorithms, moves hash size related asserts from
run time to compile time, and passes compile time definition to the
TPM2 library to increase its hash state container (it became too small
when SHA384 was disabled).

The sw context requirements should be reduced, but this is a task for
another day. We also do not have to store a local digest copy if the
API allowed reading a partial digest.

c20cff09e6 stm32: hwtimer: Use correct TIM1 interrupt
Our system timer uses capture compare mode, so the TIM1_CC interrupt
should be used.

BUG=chrome-os-partner:47851
TEST=Set TIM_CLOCK_LSB to 1 on snoball (TIM1), verify that timer
interrupts function, HOOK_SECOND hooks are called and watchdog doesn't
fire.
BRANCH=None

93760af711 mec1322: i2c: clear specified status bits
In handle_interrupt(), "|= 1 << 29" will clears all status bits, not
just bit 29. Fix this to make it only clear specified status bit and
keep R/W bits intact.

BUG=None
BRANCH=None
TEST=Verified on Kunimitus system
    1. In configure_controller() write R/W bits in completion register
    2. In handle_interrupt() print the value of completion register and
    status bits is cleared, R/W bits are kept.
