From ef45b9c395f92d9239d6c363b1f5a89f6a53f2e6 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Mon, 7 Apr 2025 22:01:54 +0200 Subject: [PATCH] spi: Introduce setup_for_spinand() A common device attached to SPI are SPI NAND and some device might require to have info on the attached NAND to know the flash page size and spare size. To support this, introduce setup_for_spinand() that pass the attached spinand info from manufacturer.
