nand_write_page_syndrome(9)

🌸 NAME 🌸

From the Kernel API Manual, bestie: nand_write_page_syndrome — [REPLACEABLE] hardware ECC syndrome based page write. That's the name tea, and it's literally nand_write_page_syndrome(9) ✨

✨ SYNOPSIS ✨

okay so the signature is giving:

int nand_write_page_syndrome (struct nand_chip *chip , const uint8_t
       *buf , int oob_required , int page );

🎀 ARGUMENTS 🎀

• chip — nand chip info structure 💖
• buf — data buffer 🎀
• oob_required — must write chip->oob_poi to OOB 👀
• page — page number to write 🦋

💅 DESCRIPTION 💅

The hw generator calculates the error syndrome automatically — no cap. Therefore we need a special oob layout and handling. That's the whole vibe of this one, bestie: special oob layout + special handling, periodt ✨
