Aligned malloc for dma and mbufs for powerpc ppc405gp

[gene.smith at siemens.com (Smith, Gene)]

I have a requirement to allocate a block of memory (on a 4KB boundary 
according to the manual) for dma descriptor. I also need to have my 
mbufs allocated on 32 byte boundaries as dma buffers. This is due to the 
ppc405gp emac and mal devices and cache line boundaries. Is there a way 
to do this in rtems using the standard API? If not, any suggestions on 
how this should be done?

Since my driver is not working I think this must be part of the problem.

Tks,
