Re: [Patch v4] net: pfe_eth: Use spi_flash_read API to access flash memory

On 13.01.20 10:23, Kuldeep Singh wrote:

Current PFE firmware access spi-nor memory directly. New spi-mem framework does not support direct memory access. So, let's use spi_flash_read API to access memory instead of directly using it.
