# Make rules for A8 - This file has all the common rules and defines required
#                     for Cortex-A8 ISA
#
# This file needs to change when:
#     1. Code generation tool chain changes (currently it uses CodeSourcery)
#     2. Internal switches (which are normally not touched) has to change
#     3. XDC specific switches change
#     4. a rule common for A8 ISA has to be added or modified
