fs: ext4: Prevent infinite loop in ext4fs_iterate_dir
If the ext3 journal gets out of sync with what is written on disk, for
example because of an unexpected power cut, ext4fs_read_file can
return an all-zero directory entry. In that case, ext4fs_iterate_dir
would infinite loop.
This patch detects when a directory entry's direntlen member is 0 and
returns a failure status, which breaks out of the infinite loop. As a
result, U-Boot will not find files that may subsequently be recovered
when the journal is replayed.
This is better behaviour than hanging in an infinite loop, but as a
further improvement maybe U-Boot could interpret the ext3 journal and

This can be verified by reading the value of the AHB1_APB1_CFG_REG
register via /dev/mem. It always reads as 0x3180 regardless of
the current cpufreq operating point. So this configuration should
be safe for use in U-Boot too.
PLL6 also needs to be configured before it is used as the clock
source, according to the "CCU / Programming Guidelines" section
of the Allwinner manual.

speed when booting via FEL. This patch can increase the FEL USB

It is possible that this may prove useful for non-test situations. For
example the console output may be suppressed for normal operations, but
recorded and stored for access by the OS. That feature is not implemented
at present.

Add a circular memory buffer implementation
This will be used to support console recording. It provides for a circular
buffer which can be written at the head and read from the tail. It supports
avoiding data copying by providing raw access to the data.

Move console definitions into a new console.h file
The console includes a global variable and several functions that are only
used by a small subset of U-Boot files. Before adding more functions, move
the definitions into their own header file.

sandbox: Add a way to skip time delays
Some tests are slow due to delays which are unnecessary on sandbox. The
worst offender is USB where we lose two seconds. Add a way to disable time
delays.
