Reserved blocks are used for storing bad block tables. With "nand bad"
command, these reserved blocks are shown as bad blocks. This is leading
to confusion when compared with Linux bad blocks. Hence, display
"bbt reserved" when printing reserved blocks with "nand bad" command.
To acheive this, return 2 which represents reserved from nand_isbad_bbt()
instead of 1 in case of reserved blocks and catch it in cmd/nand.c.
"nand bad" command display's hexadecimal numbers, so add "0x" prefix.

To quote the author:
Since U-Boot's tracing feature was originally written, quite a few changes
have taken place in this domain. The original text format used by tracing
is still emitted by Linux, but a new trace-cmd tool has invented a binary
format which is now used by new tools, such as kernelshark.
With recent distributions and the move to Python 3, the old pybootchart
tool does not build or run. Unfortunately there is no 1:1 replacement for
the features that were provided by pybootchart, or at least it is not
obvious. Still, it makes sense to keep with the times.
This series updates proftool to use the new binary format, adding support
for function and funcgraph tracing, so that U-Boot's trace records can be
examined by trace-cmd and kernelshark.
This series also adds support for a flamegraph, which provides a visual
way to see which functions are called a lot, as well as which ones consume
the most time.
Some minor updates to the trace implementation within U-Boot are included,
to provide a little more information and to fix a few problems.
No unit tests are provided by proftool, but a functional test ensures that
sandbox can emit traces which can be processed by proftool, then parsed by
trace-cmd and that the timing of the various formats looks consistent.
