Reads of the TPM fifo by the Host are done in chunks of up to 63 bytes
at a time. The existing routine used to copy data read from the TPM
layer to the I2CS fifo operates one byte at a time. This method is
fine for single and four byte register reads. However, for larger
buffers the performace can be improved by aligning the the fifo write
pointer to be at a word boundary.

This CL adds support for reading of TPM fifo registers. Since I2C does
not provide means to communicate how many bytes the host wants to read
there must be some handshake involved between the host and Cr50.
The method added by this CL to allow Host reads of the TPM fifo
assumes the following steps:
1. Host reads burstcount from Cr50 (which will be set to default 63)
2. Host reads 1st 10 bytes of the TPM response.
3. Cr50 will copy MIN(burstcount, msg_len) bytes into its I2CS HW fifo
4. Host computes msg_len and calculates amount of data still buffered
5. Host does a TPM fifo read of buffered data only
(The following steps are repeated until the response read is complete)
6. Host reads burstcount from STS register.
7. Host issues read of burscount bytes from TPM fifo
8. I2CS will copy burstcount amount of bytes in to I2CS HW fifo
9. TPM layer sets burstcount to MIN(63, remaining msg bytes)
The version register is treated similar to a fifo access. The data
written or the number of bytes is a don't care, but there must be
at least one byte of data written with the version register write.
In the case of reads, the host must read burstcount bytes of the
version register. If burstcount is longer than the Cr50 version string
there is no issue because the version register read function always
returns the number of bytes requested, stuffing in 0s once the end of
the version string is reached.

Created test code in coreboot that exercises TPM register reads and

to detect when it is on reef and modifies the ccd behavior to
initialize usb on the AP phy when ccd is disabled. On gru the cr50
behavior is unchanged.
In RDD this change removes the checks that the current_map is the
correct one based on the detected debug state. rdd_init calls
rdd_interrupt to set up the usb and ccd state correctly. Having that
check prevents that initial rdd_interrupt from calling rdd_detached.
Before rdd_detached just disabled usb and we knew during init it
would already be disabled. Now we want to make sure it is called if a
debug accessory is not attached to initialize usb on the AP PHY.

Nothing has used this config option since Spring and Skate, back
in early 2014. There's nothing in ToT that uses it at all. I want
to add something similar for other purposes, and having two
similar-sounding options will just cause confusion.
NOTE: Although the comments in include/system.h said that the two
functions
system_get_console_force_enabled()
system_set_console_force_enabled()
were only useful when CONFIG_CONSOLE_RESTRICTED_INPUT is defined,
they were being used in chip/stm32/system.c. But since the
bkpdata registers are only accessible to the EC, there was no way
to initialize or modify the one relevant bit that those functions
cared about, so they almost certainly had no effect.

The nvmem_write() and nvmem_move() funcitons return an error
if the write or move operation would exceed the user buffer
boundary. However, the TPM2 functions which call these functions
do not check for errors. Instead TPM2 NvMem relies on the return
value of the nv_commit() function to determine if a TPM command
which modifies NvMem succeeds or fails.
This CL adds a nvmem_write_error flag which is set in cases where
an nvmem_write/nvmem_move returns an error. This error flag
is then checked in nvmem_commit() so that the commit operation can
be abandonded and the error returned back up the TPM2 stack.
Tested in full system for two cases.
Installed TPM certificates on the Cr50, then manually erased NvMem with
flasherase 0x7b000 0x5000 and rebooted system. Then on Kevin console
entered the command <trunks_client --own>
NV_MEMORY_SIZE = 9932
NVMEM_TPM_SIZE = 7168
Case 1 -> Without internal write error state, so commit() always
executes if called. In this case, the Kevin console reports
a TRUNKS_RC_WRITE_ERROR and there is a Cr50 reboot.

In this case, the attempted write overflow sets the internal error
state and the commit() following attempted overflow detection is not
