Message:

1/ introducing support to display images on the frame buffer
with the vci_chbuf_dma (in stdio.c and drivers.c)
2/ introducing support for mem_cache configuration segment
as the memory cache is considered as another addressable peripheral type
(in drivers.c)
3/ Introducing the new "increment" parameter in the mapping header.
This parameter define the virtual address increment for the vsegs
associated to the replicated peripherals (ICU, XICU, MDMA, TIMER, MMC).
This parameter is mandatory, and all map.xml files the "mappings"
directory have been updated.
