cpu9260: update board support
- update to new relocation code - switch to boards.cfg - get rid of LEGACY (still a little hack in .h to compile) - add nand boot configuration - boot tested for the following configurations : 9260 (64MB RAM & nor boot) 9260_nand (64MB RAM & nand boot) 9G20_128M (128MB RAM & nor boot) 9G20_nand_128M (128MB RAM & nand boot) (nor boot is using lowlevel init) Signed-off-by: Eric BĂ©nard <eric@eukrea.com>
