I thought not. 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.

Your one may be a little easier to understand, but if someone switches a board over to OF_PLATDATA then it will be confusing... Please let me know which you prefer. Regards, Simon

OF_PLATDATA is used to reduce the size of the SPL, right? In most cases, some rk3288 boards use OF_LIBFDT. If OF_PLATDATA is really required, I think your comment is very clear. I perfer my above opinion? :-) > Regards, > Simon > > >
