The application may need to read/write/erase the flash memory,

CONFIG_FLASH_PHYSICAL, which allows the higher-level CONFIG_FLASH

TPM resets happen asynchronously, conceivably there is some interface
(i2cs or sps) activity under way when TPM is reset.
Sps driver provides a means of disconnecting the client of the driver,
while the i2cs driver does not. Come to think of it, there is no real
need to provide a special function to disconnect a client, this makes
API simpler and allows to add driver initialization to the client
registration function.
To make tpm_registers.c more flexible - allow to register a callback
for interface initialization, this way when TPM is reset, the
interface can be also re-initialized and is guaranteed to start from
scratch after reset.

There is now a call to reset the retry counter before the hard reset
after an update. Cr50 will use the updated image for the next 5 boots,
but on the 6th it sees the retry counter is greater than 5 and then
jumps back to the old image. Cr50 needs to call
system_process_retry_counter to reset the counter and corrupt the old
image header to prevent falling back to the old image.
Normally the reset counter would be processed after it receives a TPM
command. Reef does not have Cr50 TPM support. Until Cr50 has TPM
support for Reef, Cr50 should have a different point to know when the
update is good. This change adds a board property to mark the process
the reset counter once the Cr50 USB controller receives a set address
request from the host. On Reef the controller defaults to the AP PHY
when suzyq is not connected, so it should have a connection to the AP

CONFIG_POWER_TRACK_HOST_SLEEP_STATE has a dependency on
CONFIG_POWER_COMMON, so remove it from test builds that don't have a
chipset task, rather than heavy-handedly removing it from all test
builds.

stm32f446 uses a synopsys designware USB block
rather than the typical ST one. This change adds driver support
for the new block, including usb console support.

Add a policy to handle the case where the device can source the
`CONFIG_USB_PD_MAX_SINGLE_SOURCE_CURRENT` over one of its type-C port if
there is no sink connected on the other ones.

UART0 RX only needs to be disabled on reef. This change uses a system
property instead of a #define to disable UART0 RX that way it can just
be done on Reef not Gru or the dev board.

gru kevin and reef still boot.
Connect DIOA13 to DIOA1 on the dev board and verify the console
can be used.

This adds support for CONFIG_RESTRICTED_CONSOLE_COMMANDS. If the
appropriate options are configured, restricted commands can be
prevented from running.
Nothing in this CL actually uses that, but it works if you turn
it on.
BUG=chrome-os-partner:55322
BRANCH=none
TEST=make buildall, test on Cr50 hardware
I also tested it manually. If you add this to board.h:
#define CONFIG_CONSOLE_COMMAND_FLAGS
#define CONFIG_RESTRICTED_CONSOLE_COMMANDS
#define CONFIG_CONSOLE_COMMAND_FLAGS_DEFAULT CMD_FLAG_RESTRICTED
and this to board.c:
static int restricted_state;
int console_is_restricted(void)
{
return restricted_state;
}
static int command_lock(int argc, char **argv)
{
int enabled;
if (argc > 1) {
if (!parse_bool(argv[1], &enabled))
return EC_ERROR_PARAM1;
restricted_state = enabled;
}
ccprintf("The restricted console lock is %s\n",
restricted_state ? "enabled" : "disabled");
return EC_SUCCESS;
}
DECLARE_CONSOLE_COMMAND_FLAGS(lock, command_lock,
"[<BOOLEAN>]",
"Get/Set the restricted console lock",
0); /* no restrictions */
then you can use the "lock" command to enable and disable every
other console command except for it and "help".

If we add a .flags field to the console commands data structure,
we can use it to distinguish some commands from others, for
example to mark some commands as safe and others as dangerous.
This just adds the undefined CONFIG_ options. They aren't used
anywhere, so there's no behavioral difference yet.
