[PATCH] bcm53xx: add nand subtarget

Arınç ÜNAL arinc.unal at arinc9.com
Sat Aug 19 08:09:04 PDT 2023


The NVMEM_BRCM_NVRAM driver won't work properly with NVRAM in NAND. It
causes the devices with NVRAM in NAND to bootloop. Create a subtarget for
NAND devices and disable the driver on it.

Disable NVMEM too as the bgmac_bcma driver will hang trying to retrieve the
MAC address without NVMEM_BRCM_NVRAM enabled.
