hm2_tram_add_bspi_frame

NAME

hm2_tram_add_bspi_frame — add a register-write to the Hostmot2 TRAM

SYNTAX

hm2_tram_add_bspi_frame ( char *name, int chan, u32 wbuff, u32 rbuff )

DESCRIPTION

hm2_tram_add_bspi_frame Add a regular (every thread) write event to the Hostmot2 tram for bspi instance "name". "name" is a unique string given to each bspi channel during hostmot2 setup.
The names of the available channels are printed to standard output during the driver loading process and take the form:
hm2_<board name>.<board index>.bspi.<index>
For example
hm2_5i23.0.bspi.0

This function is used to add a regular, every thread, write or write-read transaction to the Translation RAM system.
A write need not have a read (use 0 for **rbuff) but it is an error to have a read without a write.
Note that the TRAM list is not actioned until the hm2_allocate_bspi_tram function is called.
The read and write parameters must be pointers to pointers, as TRAM re-maps the buffers into contiguous memory.

RETURN VALUE

Returns 0 on success and -1 on failure.
