[U-Boot] [PATCH 2/2] cpu9260: update board support
Eric Bénard
eric at eukrea.com
Tue Jan 25 23:31:24 CET 2011
- 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)
