[U-Boot] [PATCH] spl:falcon:trats Update Trats default board configuration file to support FALCON MODE

[Lukasz Majewski]

Hi Minkyu,

> Support for a new command (defined at envs) - spl_export generates
> the ATAGS image necessary for fast boot. Afterwards, it is stored
> at ext4 partition.
> 
> Generated image format:
> CRC [4B] SIZE [4B] PAYLOAD(ATAGS/DT) [SIZE]
> 
> Remarks:
> - CRC is calculated only for PAYLOAD
> - SIZE is the size of PAYLOAD
> 
> It is important to adjust ${splsize} when large image is generated.
> It is defined as hex, since ext4 related commands expect it.
> 
> The ${spladdr} environment variable corresponds to
> CONFIG_SYS_SPL_ARGS_ADDR
> 
> Additionally definitions for DFU have been refactored and support for
> EFI has been added as well.

Could this patch be added to u-boot-samsung tree? It brings many
updates for trats configuration and it would be nice to bring it to
2013.01 u-boot release.
