i don't use the bsp , i only use uboot, configure regeister under the uboot, i say configure regeisters,as example CS0

i configure:

IOMUXC_GPR1 value is 0x410249,mean  cs0~cs3 all 32M

IOMUXC_SW_MUX_CTL_PAD_EPDC_PWR_CTRL2 value is 0x03, mean EIM_CS0_B

Pad Mux Register's EIM_EB0 EIM_EB1 EIM_EB2 EIM_EB3 EIM_OE EIM_RW EIM_LBA EIM_ADDR0 ~ EIMADDR20  EIM_DATA0~EIM_DATA15  all value is 0x03,mean set eim mode 

EIM_CS0GCR1  value is 0x4104B1

EIM_CS0GCR2 value is 0x1

EIM_CS0RCR1 value is 0x1c212412

EIM_CS0RCR2 value is 0x0

EIM_CS0WCR1 value is 0x1c40088a

EIM_CS0WCR2 value is 0x0

i want to know ,if eim can function normal , configure these regeister is right ? if  OK, i will find read and write time sequence configrtion.
