1002 Provides an 'iotrace' command which supports recording I/O reads and
1003 writes in a trace buffer in memory . It also maintains a checksum
1004 of the trace records (even if space is exhausted) so that the
1005 sequence of I/O accesses can be verified.
1006
1007 When debugging drivers it is useful to see what I/O accesses were
1008 done and in what order.
1009
1010 Even if the individual accesses are of little interest it can be
1011 useful to verify that the access pattern is consistent each time
1012 an operation is performed. In this case a checksum can be used to
1013 characterise the operation of a driver. The checksum can be compared
1014 across different runs of the operation to verify that the driver is
1015 working properly.
1016
1017 In particular, when performing major refactoring of the driver, where
1018 the access pattern should not change, the checksum provides assurance
1019 that the refactoring work has not broken the driver.
1020
1021 This works by sneaking into the io.h heder for an architecture and
1022 redirecting I/O accesses through iotrace's tracing mechanism.
1023
1024 For now no commands are provided to examine the trace buffer. The
1025 format is fairly simple, so 'md' is a reasonable substitute.
1026
1027 Note: The checksum feature is only useful for I/O regions where the
1028 contents do not change outside of software control. Where this is not
1029 suitable you can fall back to manually comparing the addresses. It
1030 might be useful to enhance tracing to only checksum the accesses and
1031 not the data read/written.

1991 This is used with the Freescale secure boot mechanism.
1992
1993 Freescale's SEC block has built-in Blob Protocol which provides
1994 a method for protecting user-defined data across system power
1995 cycles. SEC block protects data in a data structure called a Blob,
1996 which provides both confidentiality and integrity protection.
1997
1998 Encapsulating data as a blob
1999 Each time that the Blob Protocol is used to protect data, a
2000 different randomly generated key is used to encrypt the data.
2001 This random key is itself encrypted using a key which is derived
2002 from SoC's non-volatile secret key and a 16 bit Key identifier.
2003 The resulting encrypted key along with encrypted data is called a
2004 blob. The non-volatile secure key is available for use only during
2005 secure boot.
