1149config CMD_IOTRACE
1150 bool "iotrace - Support for tracing I/O activity"
1151 help
1152 Provides an 'iotrace' command which supports recording I/O reads and
1153 writes in a trace buffer in memory . It also maintains a checksum
1154 of the trace records (even if space is exhausted) so that the
1155 sequence of I/O accesses can be verified.
1156
1157 When debugging drivers it is useful to see what I/O accesses were
1158 done and in what order.
1159
1160 Even if the individual accesses are of little interest it can be
1161 useful to verify that the access pattern is consistent each time
1162 an operation is performed. In this case a checksum can be used to
1163 characterise the operation of a driver. The checksum can be compared
1164 across different runs of the operation to verify that the driver is
1165 working properly.
1166
1167 In particular, when performing major refactoring of the driver, where
1168 the access pattern should not change, the checksum provides assurance
1169 that the refactoring work has not broken the driver.
1170
1171 This works by sneaking into the io.h heder for an architecture and
1172 redirecting I/O accesses through iotrace's tracing mechanism.
1173
1174 For now no commands are provided to examine the trace buffer. The
1175 format is fairly simple, so 'md' is a reasonable substitute.
1176
1177 Note: The checksum feature is only useful for I/O regions where the
1178 contents do not change outside of software control. Where this is not
1179 suitable you can fall back to manually comparing the addresses. It
1180 might be useful to enhance tracing to only checksum the accesses and
1181 not the data read/written.

2288 from SoC's non-volatile secret key and a 16 bit Key identifier.

2698 UBI is a software layer above MTD layer which admits use of LVM-like
2699 logical volumes on top of MTD devices, hides some complexities of
2700 flash chips like wear and bad blocks and provides some other useful
2701 capabilities. Please, consult the MTD web site for more details
2702 (www.linux-mtd.infradead.org). Activate this option if you want
2703 to use U-Boot UBI commands.
