gitinfo:
meta-yocto        = "master:1fd9a16d2a4594a4e9179dc7353ac51ce32eb712"
meta-fsl-ppc      = "master:8b14fc1436eb204d961c45f5515748c5636ceed6"

When running "dmesg | grep error", I got some error messages in the output:
############
root@p1022ds:~# dmesg | grep error
fsl-l2ctlr: probe of ffe20000.l2-cache-controller failed with error -22
fsl-pq_mdio: probe of ffe25000.mdio failed with error -16
snd-soc-p1022ds: probe of snd-soc-p1022ds.0 failed with error -22

1. fix "fsl-l2ctlr: probe of ffe20000.l2-cache-controller failed with error -22"
by set 'othbootargs ' in uboot.
u-boot setting:
#######################
setenv othbootargs cache-sram=0xfff00000,0x8000
#######################

2. fix "snd-soc-p1022ds: probe of snd-soc-p1022ds.0 failed with error -22"
   by set 'hwconfig' in uboot.
u-boot setting:
#######################
setenv hwconfig audclk:12
#######################

3. "fsl-pq_mdio: probe of ffe25000.mdio failed with error -16"
   fsl-pq_mdio can config for two PHY . 
   there is only PHY in some p1022ds boards. 
   so ,there are errors sometime.

set 'othbootargs ' and 'hwconfig' in uboot.
