Hello!
BOARD: QuadMo747-X/T20
i get kernel 2.6.36.2 from nvidia tegra partners: Toradex Colibri (http://developer.toradex.com/software-resources/arm-family/linux/source-code/linux-(colibri-t20)-source-code), and SecoQseven (http://www.secoqseven.com/en/download/downloads.html)


I build kernel with option "User mode SPI device support"
Example of my board-harmony.c file in attachment

While 

echo -ne "x5c">/dev/spidev1.1 &  
kernel module interface spi freezes. (bash not responding, and ignore SIGKILL)
if i run spidev_test.c from Documentation/spi folder - process spidev_test freezes

For that kernel, you will need to get support from whoever supplied the
kernel; Toradex or Seco.

If you can reproduce the problem using an upstream kernel instead, then
this list may be an appropriate place to get support. Feel free to ask
questions about porting the upstream kernel to your board here.

By the way in the upstream kernel 3.8.5 in my opinion there is no header file with registers of tegra t20?

Which aspect of the registers?

If you mean the base address of each HW module: that is described in
device-tree now. See arch/arm/boot/dts/tegra20.dtsi.

If you mean the individual register fields for each module, those are
part of the individual drivers; either in the .c file or an accompanying
.h file. For example, drivers/gpio/gpio-tegra.c or
sound/soc/tegra/tegra20_i2s.h.
