[U-Boot] U-boot initialization test

Hello,

Below is my board initialization process :

U-Boot 1.3.1 (Nov 27 2008 - 08:30:43) MPC83XX

Reset Status: Software Hard, External/Internal Soft, External/Internal Hard

CPU: e300c1, MPC8349E, Rev: 31 at 528 MHz, CSB: 264 MHz Board: MPX8349GC PCI1: 32 bit, 33 MHz SRAM: 1 MB I2C: ready DRAM: 512 MB (DDR2, 64-bit, ECC on) FLASH: 16 MB PCI: Bus Dev VenId DevId Class Int 00 0f 10cf 202b 0380 00 In: serial Out: serial Err: serial Net: TSEC0, TSEC1

During above initialization process of u-boot,

1. Does it conduct a test to all board hardware listed? 2. If above answer is yes, what method is used to do the test?
