From a11c081da3dfbef309cd21ab54b7b2582d0c9f35 Mon Sep 17 00:00:00 2001 From: Tudor Ambarus Date: Wed, 13 Nov 2019 15:42:52 +0000 Subject: mtd: spi: spi-nor-core: Add SST vendor specific SFDP parser JESD216 allow vendors to define their own SFDP tables. Add SST SFDP parser. The vendor table is allocated using resource-managed kmalloc - the table will be freed on driver detach. It will be accessible by getting the UCLASS_SPI_FLASH's private data. The SST's SFDP table is particularly of interest because contains pre-programmed globally unique EUI-48 and EUI-64 identifiers.
