SPI bus on MPC8xx

Hello everybody,

I'm a french student, new to this list and i'm actually developping an interface to dialog via the SPI bus of a MPC852T with an HC908GR4. I have started my developpement with the driver that Alex Zeffertt made and i had a surprise when i saw that Alex use some CPM function (m8xx_cpm_dpalloc, m8xx_cpm_hostalloc, ... ) to implement his module and that those functions weren't exported in the kernel (/proc/ksyms). I'd like to konw if it was a time when those functions were exported since Alex used them and the reasons why nowadays this is no more the case.

Thanks you
