- I/O tracing:
When CONFIG_IO_TRACE is selected, U-Boot intercepts all I/O
accesses and can checksum them or write a list of them out
to memory. See the 'iotrace' command for details. This is
useful for testing device drivers since it can confirm that
the driver behaves the same way before and after a code
change. Currently this is supported on sandbox and arm. To
add support for your architecture, add '#include <iotrace.h>'

Example output from the 'iotrace stats' command is below.

still continue to operate.

Freescale Layerscape Management Complex Firmware Support:
---------------------------------------------------------
The Freescale Layerscape Management Complex (MC) supports the loading of
"firmware".
This firmware often needs to be loaded during U-Boot booting, so macros
are used to identify the storage device (NOR flash, SPI, etc) and the address
within that device.
- CONFIG_FSL_MC_ENET
Enable the MC driver for Layerscape SoCs.
- CONFIG_SYS_LS_MC_FW_ADDR
The address in the storage device where the firmware is located. The
meaning of this address depends on which CONFIG_SYS_LS_MC_FW_IN_xxx macro
is also specified.
- CONFIG_SYS_LS_MC_FW_LENGTH
The maximum possible size of the firmware. The firmware binary format
has a field that specifies the actual size of the firmware, but it
might not be possible to read any part of the firmware unless some
local storage is allocated to hold the entire firmware first.
- CONFIG_SYS_LS_MC_FW_IN_NOR
Specifies that MC firmware is located in NOR flash, mapped as
normal addressable memory via the LBC. CONFIG_SYS_LS_MC_FW_ADDR is the
virtual address in NOR flash.
