CPU Microcode

Modern CPUs usually require a special bit stream called microcode [6] to be
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.
Driver Model
------------
x86 has been converted to use driver model for serial and GPIO.
