Message:

Introducing a major release, to suppoort the tsar_generic_leti platform
and the various (external or internal) peripherals configurations.
The map.xml format has been modified, in order to support the new
vci_iopic componentand a new policy for peripherals initialisation.
The IRQs are nom described in the XICU and IOPIC components
(and not anymore in the processors).
To enforce this major change, the map.xml file signature changed:
The signature value must be: 0xDACE2014

This new release has been tested on the tsar_generic_leti platform
for the following mappings:

• 4c_4p_sort_leti
• 4c_4p_sort_leti_ext
• 4c_4p_transpose_leti
• 4c_4p_transpose_leti_ext
• 4c_1p_four_leti_ext
