+Modern CPUs usually require a special bit stream called microcode [8] to be
 loaded on the processor after power up in order to function properly. U-Boot
 has already integrated these as hex dumps in the source tree.
 
+SMP Support
+-----------
+On a multicore system, U-Boot is executed on the bootstrap processor (BSP).
+Additional application processors (AP) can be brought up by U-Boot. In order to
+have an SMP kernel to discover all of the available processors, U-Boot needs to
+prepare configuration tables which contain the multi-CPUs information before
+loading the OS kernel. Currently U-Boot supports generating two types of tables
+for SMP, called Simple Firmware Interface (SFI) [9] and Multi-Processor (MP)
+[10] tables. The writing of these two tables are controlled by two Kconfig
+options GENERATE_SFI_TABLE and GENERATE_MP_TABLE.
