Support of the MINI2440 board from FriendlyARM from an old version of u-boot : http://repo.or.cz/r/u-boot-openmoko/mini2440.git
Currently, supporting only boot from NOR.
Signed-off-by: Gabriel Huau contact@huau-gabriel.fr --- Changes for v2: - Coding style cleanup - Remove unnecessary files modification - Remove unnecessary board configuration set
Changes for v3: - Coding style cleanup - Move some macro definition from lowlevel_init.S to a new header - Remove some "magic bloat" with I/O board initialization - Add a pll_delay and replace loop by it - Somme cleanup in the configuration file - Cancel modifications on an SoC specific header - Add my name to copyright
Changes for v4: - Move dram init to dram_init() instead low_levelinit - Remove u -boot env from configuration file and change the address of initial SP - Remove PLL init, now it's SoC specific
Changes for v5: - Clean up configuration file - Add a MAINTAINERS entry - Add a README.mini2440 file - Use gpio/iomux interface in case of magic numbers - Use get_ram_size()
Changes for v6: - Coding style cleanup - Remove some unused define in the board config
Changes for v7: - Cleanup coding style - Changement of the commit message
Changes for v8: - Replace define[tab] by define[space]
Changes for v9: - Add a nice commit message
