+	  - SPL boot does not support reading of ONFI parameters. This is done to
+	    keep SPL code foot-print small.
+	  - In current U-Boot flow using nand_init(), driver initialization
+	    happens in board_nand_init() which is called before any device probe
+	    (nand_scan_ident + nand_scan_tail), thus device's ONFI parameters are
