From 43ecc776cac9b95d5e7fa151138936d03239f439 Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Sun, 30 Oct 2016 23:16:19 +0530 Subject: [PATCH] sf: params: Add S25FS256S_64K spi flash support Add Spansion S25FS256S_64K spi flash to the list of spi_flash_ids. In spansion S25FS-S family the physical sectors are grouped as normal and parameter sectors. Parameter sectors are 4kB in size with 8 set located at the bottom or top address of a device. Normal sectors are similar to other flash family with sizes of 64kB or 32 kB. To erase whole flash using sector erase(D8h or DCh) won't effect the parameter sectors, so in order to erase these we must use 4K sector erase commands (20h or 21h) separately. So better to erase the whole flash using 4K sector erase instead of detecting these family parts again and do two different erase operations.
