Dear Gabriel Huau,
> Signed-off-by: Gabriel Huau <cont...@huau-gabriel.fr>
Cc albert please to see what's his opinion ... I'm fine with this as is.

> 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
