The Host shall set correct CRC in the argument ofCMD8. If
CRC error is detected, card returns CRC error in R1 response
regardless of command index."

| Add more generated files to .gitignore
barebox* is not limited to the toplevel directory, so this ignores
all files starting with 'barebox' from which we have several we do
not wish to ignore. Add barebox-flash-image to the ignore list which
seemed to be the motivation for the original patch.

As a new implementation of Y-Modem protocol is available,
switch from old implementation to the new one :
- remove old xyzModem* files
- remove old command loady2
- rename command loady2 to loady

The current Y-Modem implementation has some limitations:
- Y-Modem/G protocol is not supported
- Multiple files (aka. batch) transfers are not supported
- Transfer speed over fast lines (USB console) is slow
- Code is not trivial to maintain (personnal opinion)
This implementation tries to address all these points by
introducing loady2 command.
The effects are :
- transfer speed for Y-Modem over USB jumps from 2kBytes/s
to 180kBytes/s
- transfer speed for Y-Modem/G jumps to 200kBytes/s
- multiple file transfers are possible
This command was tested on a USB console and UART 9600bps
serial line :
- NAKs (and retransmissions) were tested for faulty
serial lines
- multiple file transfers were tested
- Y-Modem, Y-Modem/G and X-Modem transfers were tested

The idea of having /env/init/* scripts was to make the configuration
more flexible and customizable for boards. It turned out though that
people (including myself) do not find the place where they should
change these settings.
So this patch brings back /env/config for defenv-2. The individual
env/init/* scripts are removed and their content is added to
/env/init/config-board. This makes the values from /env/init/config-board
the board specific defaults which can be overwritten in /env/config.
