Moving the Storage buffer to SDRAM in the dev_msc_ramdisk_bm_c7 example

[andrelongo85]

Hello,

we are ruining some performance test on the RT1170 evkit and we are using the dev_msc_ramdisk_bm_cm7 example. As the storge buffer is limited by the internal DTCM size we would like to move it on the external SDRAM. We couldn't find an easy way to do it. Can anyone help us on it?

Best Regards,

Andrea
