L1 instruction memory and MMR memory on blackfin can not be accessed by common functions probe_kernel_read() and probe_kernel_write(). Blackfin asks for 2/4 byte align access to MMR memory and DMA access to L1 instruction memory. These functions need to be reimplemented in architecture specific kgdb.c.
