Subject: = Best=20 location for call to spi_register_board_info () on PPC=20 (MPC5200)

I'm working on an SPI procol driver on the MPC52XX.
I spend = some time=20 in trying to find the best location for calling = spi_register_board_info ()=20 (which basically registers the relations between protocol drivers and = the SPI=20 chip selects).

I wish to call this function from my copy of = the=20 arch/ppc/platforms/Lite5200.c file  since these relations are=20 board-specific, however I found that placing the call in any of these=20 functions (eg. lite5200_setup_arch) results in an -ENOMEM from the=20 spi_register_board_info () call.

Now I'm calling=20 spi_register_board_info () from the spi controller driver which is soo = ugly.

Thanks in advance,

Henk.
