The SPEAr600 Serial Memory Interface (SMI) is a dedicated serial flash
14
+
controller supporting up to four chip selects for serial NOR flashes
15
+
connected in parallel. The controller is memory-mapped and the attached
16
+
flash devices appear in the CPU address space.The driver
17
+
(drivers/mtd/devices/spear_smi.c) probes the attached flashes
18
+
dynamically by sending commands (e.g., RDID) to each bank.
19
+
Flash sub nodes describe the memory range and optional per-flash
20
+
properties.
