Yes, only firefly-rk3288 board use OF_PLATDATA. But driver get 
rk3288_sdram_channel via fdtdec_get_byte_array with the size which is  
sizeof(struct rk3288_sdram_channel).
In commit 9ca7e67 rockchip: Update the sdram-channel property to support 
of-platdata, you add dummy element in struct rk3288_sdram_channel and 
size was changed to 9.
Without this fix, driver get rk3288_sdram_channel failed.

Maybe add CONFIG_IS_ENABLED(OF_PLATDATA) for distinction is better, how 
about?

struct rk3288_sdram_channel {
     u8 rank;
     u8 col;
     u8 bk;
     u8 bw;
     u8 dbw;
     u8 row_3_4;
     u8 cs0_row;
     u8 cs1_row;
#if CONFIG_IS_ENABLED(OF_PLATDATA)
     /*
      * For of-platdata, which would otherwise convert this into two
      * byte-swapped integers. With a size of 9 bytes, this struct will
      * appear in of-platdata as a byte array.
      */
     u8 dummy;
#endif
};
