[PATCH 0/5] arch/arm: mioa701 linux booting

[Robert Jarzmik]

This patch serie makes linux autobooting and barebox flashing
and reflashing much more automated.
This serie serves as the first fully working barebox setup,
fully replacing the existing legacy boot code on the mioa701.

[PATCH 2/5] arch/arm: mioa701 make autoboot of Linux work

[Robert Jarzmik]

Make the autoboot work :
 - if no USB cuable is plugged, continue directly to
   autoboot
 - if an USB cable is plugged, wait for 3 seconds for
   any input on the USB serial gadget, and if none
   happens, continue to autoboot linux kernel
 - else interrupt autoboot and interact on barebox
   console

[PATCH 3/5] arch/arm: mioa701 add IPL and DPS1 updater

[Robert Jarzmik]

In order for barebox to be functional, the docg3 DPS1 has to
protect barebox from writes, and have its embedded IPL coded
to load barebox (as barebox is the SPL).

Add a raw DPS1, which :
 - protects the area from block 6 to block 123
   This is DPS1 + barebox + barebox-logo
 - encodes the 2048 bytes IPL

[PATCH 4/5] arch/arm: mioa701 use maximum CPU frequency

[Robert Jarzmik]

To speed-up linux kernel loading, switch the PXA cpu to the
maximum allowed frequency (520 MHz). This improves the load
time from several seconds to less than a second from the
MTD.
