🦋 spi_nor_init_erase_cmd_list(9) — initialize erase command list 🦋

okay so bestie, this is the Kernel API Manual page for spi_nor_init_erase_cmd_list(9), and the vibe is very “we are setting up the erase command list” ✨ no cap, every detail is staying right here.

💖 NAME 💖

spi_nor_init_erase_cmd_list — initialize erase command list

🌸 SYNOPSIS 🌸

int spi_nor_init_erase_cmd_list (struct spi_nor *nor , struct list_head
       *erase_list , u64 addr , u32 len );

🎀 ARGUMENTS 🎀

• nor — pointer to a struct spi_nor, bestie 🌱
• erase_list — list of erase commands to be executed once we validate that the erase can be performed. that validation part is important 👀
• addr — offset in the serial flash memory 📍
• len — number of bytes to erase 🧮

🫶 DESCRIPTION 🫶

Builds the list of best fitted erase commands and verifies if the erase can be performed. it’s giving prep work, but make it iconic 💅

⭐ RETURN ⭐

0 on success, -errno otherwise. slay when it’s zero, errno when it’s not 😭
