![Baruch Siach](/assets/img/avatar_default.png)
Add support for read/write of ONIE "Tlvinfo" EEPROM data format. TLV
stands for Type-Length-Value. The data format is described here:
https://opencomputeproject.github.io/onie/design-spec/hw_requirements.html#board-eeprom-information-format
Based on U-Boot patch from the Open Compute project:
ec87e872d4/patches/u-boot/common/feature-sys-eeprom-tlv-common.patch
Keep only I2C EEPROM support. Use the generic eeprom driver. Fix
checkpatch issues.
Add support for multiple EEPROM TLV stores on the same system. This is
useful in case of SOM and carrier that both provide ID and hardware
configuration information.
Add option to enable for SPL. This allows selection of RAM configuration
based on EEPROM stored board identification.

Provides an 'iotrace' command which supports recording I/O reads and

writes in a trace buffer in memory . It also maintains a checksum
|
|
of the trace records (even if space is exhausted) so that the
|
|
sequence of I/O accesses can be verified.
|
|
|
|
When debugging drivers it is useful to see what I/O accesses were
|
|
done and in what order.
|
|
|
|
Even if the individual accesses are of little interest it can be
|
|
useful to verify that the access pattern is consistent each time
|
|
an operation is performed. In this case a checksum can be used to
|
|
characterise the operation of a driver. The checksum can be compared
|
|
across different runs of the operation to verify that the driver is
|
|
working properly.
|
|
|
|
In particular, when performing major refactoring of the driver, where
|
|
the access pattern should not change, the checksum provides assurance
|
|
that the refactoring work has not broken the driver.
|
|
|
|
This works by sneaking into the io.h heder for an architecture and
|
|
redirecting I/O accesses through iotrace's tracing mechanism.
|
|
|
|
For now no commands are provided to examine the trace buffer. The
|
|
format is fairly simple, so 'md' is a reasonable substitute.
|
|
|
|
Note: The checksum feature is only useful for I/O regions where the
|
|
contents do not change outside of software control. Where this is not
|
|
suitable you can fall back to manually comparing the addresses. It
|
|
might be useful to enhance tracing to only checksum the accesses and
|
|
not the data read/written.

This is used with the Freescale secure boot mechanism.
|

Freescale's SEC block has built-in Blob Protocol which provides
|
|
a method for protecting user-defined data across system power
|
|
cycles. SEC block protects data in a data structure called a Blob,
|
|
which provides both confidentiality and integrity protection.
|
|

|
Encapsulating data as a blob
|
|
Each time that the Blob Protocol is used to protect data, a
|
|
different randomly generated key is used to encrypt the data.
|
|
This random key is itself encrypted using a key which is derived
|
|
from SoC's non-volatile secret key and a 16 bit Key identifier.
|
|
The resulting encrypted key along with encrypted data is called a
|
|
blob. The non-volatile secure key is available for use only during
|
|
secure boot.

During decapsulation, the reverse process is performed to get back
|
|
the original data.
