Hello Andre,
being compatible to Linux is the goal. If this doesn't work, then this
is a bug. You can add a ticket for this and fix the issues.

I discovered that the Spidev include (linux/spi/spidev.h) contains different
implementations of the ioctl structure when comparing rtems and linux.
I used the mode value of the structure and wanted to compile the application
for rtems and linux, that is where I got some errors.
A few further value names differ also: cs, word_delay_usecs, pad.
I don't think the "pad" member should be used by an application.
Does anybody now why there is this difference?
Or is it not necessary to use the mode value for the ioctl commands?
On rtems it looks like this:
struct spi_ioc_transfer {
void *rx_buf;
const void *tx_buf;
Maybe use uintptr_t instead of void *.
