The PMECC driver will check minimum required ecc on ONFI parameter from NAND flash. If pmecc-cap, pmecc-sector-size in dts file is specified, use those two. otherwise, set those according to NAND flash ONFI parameters. If the pmecc-cap, pmecc-sector-size in dts are different with ecc requirement in ONFI, print out a warning. For the following compile error: ERROR (phandle_references): Reference to non-existent node or label "pinctrl_ssc0_tx" ERROR: Input tree has errors, aborting (use -f to force output) make[2]: *** [arch/arm/boot/dts/at91sam9g20ek.dtb] Error 2 the fixes are already merged in Linux mainline in v3.8-rc4. you can find in: 544ae6b2e676c3c37fb8c93ef9327932fc2e5bc2 (ARM: at91/dts: add pinctrl support for SSC peripheral) ea03c81521bde526570e1dec96eaa21fe5ac84a2 (ASoC: atmel-ssc: add pinctrl selection to driver) Change logs: v2: rebase to v3.8-rc3. And wrapped the commit message. v3: big chages: 1. reduce the PMECC lookup table mapping. Just the lookup table not whole ROM code according to J.C's suggestion. 2. use simpler strategy to handle pmecc-cap, pmecc-sector-size: * make pmecc-cap, pmecc-sector-size optional. * If pmecc-cap, pmecc-sector-size are not set, use ONFI ecc parameters. otherwise, use those in DTS file. * print out a warning if PMECC use different ecc bits or sector size from ONFI ecc parameters.
