The lamobo-r1 board, sometimes called the BPI-R1 but not labelled as such
on the PCB, is meant as a A20 based router board. As such the board comes
with a built-in switch chip giving it 5 gigabit ethernet ports, and it
has a large empty area on the pcb with mounting holes which will fit a
2.5 inch harddisk. To complete its networking features it has a
Realtek RTL8192CU for WiFi 802.11 b/g/n.

These files are based on the current latest upstream kernel work. The

The 3.4 kernel from the Allwinner SDK is clocking AHB1 at 200MHz
on Allwinner H3 and using PLL6 as the clock source (PLL6/3).
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.

The current low AHB1 clock speed is limiting the USB transfer
speed when booting via FEL. This patch can increase the FEL USB
transfer speed from ~510 KB/s to ~950 KB/s.

The DFU protocol implementation in U-Boot is much faster than the
FEL protocol implementation in the boot ROM on Allwinner devices.
Using DFU instead of FEL improves the USB transfer speed from
500-900 KB/s to 3.2-3.7 MB/s. This is particularly useful for
reducing the time needed for booting systems with large initrd
images.

FEL is still useful for loading the U-Boot bootloader and a boot
script, which may then activate DFU in the following way:

   setenv dfu_alt_info ${dfu_alt_info_ram}
   dfu 0 ram 0
   bootm ${kernel_addr_r} ${ramdisk_addr_r} ${fdt_addr_r}

The rest of the files can be transferred to the device using the
"dfu-util" tool.

Allow console recording so that tests can use it. Also allow the console
output to be suppressed, to reduce test output 'noise'.
Signed-off-by: NSimon Glass <sjg@chromium.org>

It is useful to be able to record console output and provide console input
via a buffer. This provides sandbox with the ability to run a command and
check its output. If the console is set to silent then no visible output
is generated.

This also provides a means to fix the problem where tests produce unwanted
output, such as errors or warnings. This can be confusing. We can instead
set the console to silent and record this output. It can be checked later
in the test if required.

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.
