mtd: nand: add a shorthand to generate nand_ecc_caps structure
struct nand_ecc_caps was designed as flexible as possible to support multiple stepsizes (like sunxi_nand.c). So, we need to write multiple arrays even for the simplest case. I guess many controllers support a single stepsize, so here is a shorthand macro for the case. It allows to describe like ... NAND_ECC_CAPS_SINGLE(denali_pci_ecc_caps, denali_calc_ecc_bytes, 512, 8, 15); ... instead of static const int denali_pci_ecc_strengths[] = {8, 15}; static const struct nand_ecc_step_info denali_pci_ecc_stepinfo = { .stepsize = 512, .strengths = denali_pci_ecc_strengths, .nstrengths = ARRAY_SIZE(denali_pci_ecc_strengths), }; static const struct nand_ecc_caps denali_pci_ecc_caps = { .stepinfos = &denali_pci_ecc_stepinfo, .nstepinfos = 1, .calc_ecc_bytes = denali_calc_ecc_bytes, }; Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> [Linux commit: a03c60178c181767ecfb26fb311a88742d228118]
