Now I tried to boot openwrt kernel image and it is working fine on
tested espressobin v5 unit. I compiled u-boot with all those a37xx
patches.

DRAM:  512 MiB
Comphy-0: USB3_HOST0    5 Gbps    
Comphy-1: PEX0          2.5 Gbps  
Comphy-2: SATA0         5 Gbps    
SATA link 0 timeout.
AHCI 0001.0300 32 slots 1 ports 6 Gbps 0x1 impl SATA mode

mmc0 is current device
