5This BSP is designed to support multiple Motorola PowerPC boards.  The
6following extract from some email from Eric Valette should provide
7the basic information required to use this BSP on other models.

41In theory, each board starting with 0x1E0 should be really straighforward
42to port (604 proc or above and raven host bridge...).

44Joel> Then we just have to add README.BOARD_MODEL and TIMES.BOARD_MODEL
45
46I should also make a README to explain that some file containing
47switch statement should be completed (e.g libbsp/powerpc/shared/irq_init.c
48[NOTE: This is that README. :) ]

94NB : re readding the code I should have done a switch... TSSSS.A future patche
95     I think.
