STRUCT NFC_CFG(9)

💖 NAME 💖

Hey bestie, welcome to the struct nfc_cfg(9) page from the Kernel API Manual — and it's literally the Rockchip NAND controller configuration struct. That's the whole vibe: one iconic struct holding the NAND controller's config, offsets, and ECC status bits. No cap 🫶

✨ SYNOPSIS ✨

       struct nfc_cfg {
           enum nfc_type type;
           u8 ecc_strengths[NFC_ECC_MAX_MODES];
           u32 ecc_cfgs[NFC_ECC_MAX_MODES];
           u32 flctl_off;
           u32 bchctl_off;
           u32 dma_cfg_off;
           u32 dma_data_buf_off;
           u32 dma_oob_buf_off;
           u32 dma_st_off;
           u32 bch_st_off;
           u32 randmz_off;
           u32 int_en_off;
           u32 int_clr_off;
           u32 int_st_off;
           u32 oob0_off;
           u32 oob1_off;
           struct rk_ecc_cnt_status ecc0;
           struct rk_ecc_cnt_status ecc1;
        };

🧚 Members 🧚

Okay so here's the member-by-member breakdown, and yes, every single one is important 💅

• type — NFC version.
• ecc_strengths — ECC strengths.
• ecc_cfgs — ECC config values.
• flctl_off — FLCTL register offset.
• bchctl_off — BCHCTL register offset.
• dma_cfg_off — DMA_CFG register offset.
• dma_data_buf_off — DMA_DATA_BUF register offset.
• dma_oob_buf_off — DMA_OOB_BUF register offset.
• dma_st_off — DMA_ST register offset.
• bch_st_off — BCG_ST register offset. Yes, it says BCG_ST exactly — we're keeping it exactly as written, bestie.
• randmz_off — RANDMZ register offset.
• int_en_off — interrupt enable register offset.
• int_clr_off — interrupt clean register offset.
• int_st_off — interrupt status register offset.
• oob0_off — oob0 register offset.
• oob1_off — oob1 register offset.
• ecc0 — represent ECC0 status data.
• ecc1 — represent ECC1 status data.

💌 cute sign-off: this page came from ./drivers/mtd/nand/raw, dated October 2026, and it's all about struct nfc_cfg(9). Bye bestie — go configure that Rockchip NAND controller and slay 💅✨
