From 76884835684411264cda2f15585261eb02183541 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 29 Nov 2009 15:10:44 +0000 Subject: sfc: Extend MTD driver for use with new NICs In new NICs flash is managed by firmware and we will use high-level operations on partitions rather than direct SPI commands. Add support for multiple MTD partitions per flash device and remove the direct link between MTD and SPI devices. Maintain a list of MTD partitions in struct efx_nic.
