From 5abeb06a73c6f3073f2796a726ea6dc7fb584371 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Sun, 12 Jan 2020 15:12:18 -0700 Subject: drivers/spi/spi_flash: organize spi flash by sector topology By grouping the spi flash parts by their {vendor, sector topology} tuple one can use a common probe function for looking up the part instead of having per-vendor probe functions. Additionally, by grouping by the command set one can save more space as well. SST is the exception that requires after_probe() function to unlock the parts. 2KiB of savings in each of verstage, romstage, and ramstage on Aleena Chrome OS Build.
