[U-Boot] passing board description structure when loading OS image

Hi everyone,

Is there any special reason to not pass the board description structure to OS when loading OS image ? u-boot does not pass bd_t pointer to any images not loaded with "bootm". We cannot convert our image to u-boot format and we want to access board description structure. Could you please say if there are any options to get bd_t except for direct u-boot patching ?
