-Subject: [PATCH] S3C24xx NAND: allow for faster timings
-
-Tacls can actually be zero with some NAND flash devices, so we need
-to permit this.
-
-Also, the TACLS register actually specifies the actual number of
-HCLK clocks, where the TWRPH0 and TWRPH1 registers are auto-incremented
-by one HCLK clock in hardware.
