Changeset 200 for soft/giet_vm/boot/boot_init.c

Timestamp:

Author:

Message:

+ removing some bugs from:

• xml_parser.c: check that strcmp == 0 for coproc direction
• mwmr_channel.c: mwmr->ptr to ptr.
• utils.h double definition of memcpy fonction.

+ mapping_info.h : naming the enums
+ boot_init.c: changing the order of initialisation in order

to initialise the coproc with the mwmr channel values( depth, width...).
Note that the vobjs are now physically initialised.

+ mwmr_channel.h: changing the order argument definition to suit vci_mwmr_channel Soclib componnent.
+ hwr_mapping.h: adding the register description of the vci_mwmr_controller .
