spi_nor_late_init_params(9)

✨ spi_nor_late_init_params ✨

okay bestie, so this one's from the Kernel API Manual — section 9, the big-kid kernel-functions section, we love her 💅. Pull up a chair, this is gonna be cute and educational.

---

🌸 NAME 🌸

spi_nor_late_init_params — the "late" glow-up of your default flash parameters. like, the second pass. the finishing touches. the part where the flash actually gets its whole personality 🎀

---

🦋 SYNOPSIS 🦋

int spi_nor_late_init_params (struct spi_nor *nor );

---

💖 ARGUMENTS 💖

• nor — a pointer to a struct spi_nor. that's it. that's the whole argument. she's lowkey low-maintenance, as she should be ✨

---

👑 DESCRIPTION 👑

so here's the tea ☕ — this function initializes flash parameters that aren't declared in the JESD216 SFDP standard, or for those situations where the SFDP tables just... aren't defined at all 🙈 like, no tables, no problem, we move.

it's the late init pass, so it's catching all the stuff the standard didn't cover. main character energy fr fr.

📌 heads up bestie: this function will replace the spi_nor_manufacturer_init_params method. so if you were attached to that one... yeah. she's being retired. we're passing the torch. respect the glow-up 💅
