Herve Codina 9472335eaa mtd: rawnand: fsmc: Fix timing computation ... Under certain circumstances, the timing settings calculated by the FSMC NAND controller driver were inaccurate. These settings led to incorrect data reads or fallback to timing mode 0 depending on the NAND chip used. The timing computation did not take into account the following constraint given in SPEAr3xx reference manual: twait >= tCEA - (tset * TCLK) + TOUTDEL + TINDEL Enhance the timings calculation by taking into account this additional constraint. This change has no impact on slow timing modes such as mode 0. Indeed, on mode 0, computed values are the same with and without the patch. NANDs which previously stayed in mode 0 because of fallback to mode 0 can now work at higher speeds and NANDs which were not working at all because of the corrupted data work at high speeds without troubles. Overall improvement on a Micron/MT29F1G08 (flash_speed tool): mode0 mode3 eraseblock write speed 3220 KiB/s 4511 KiB/s eraseblock read speed 4491 KiB/s 7529 KiB/s Fixes: d9fb079571 ("mtd: nand: fsmc: add support for SDR timings") Signed-off-by: Herve Codina <herve.codina@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Link: https://lore.kernel.org/linux-mtd/20211119150316.43080-5-herve.codina@bootlin.com		2021-12-03 14:33:45 +01:00
