I am back again on the subject !!
I succeeded to compile and start my own kernel, using the branch allwinner-v3.0-
android-v2 ...
But when I install the sata module (sw_ahci_platform) I have this error:

<6>ata1: EH complete
<3>ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
<3>ata1: irq_stat 0x00000040, connection status changed
<3>ata1: SError: { DevExch }
<4>ata1: limiting SATA link speed to 1.5 Gbps
<6>ata1: hard resetting link
<6>ata1: SATA link down (SStatus 1 SControl 310)
<6>ata1: EH complete
<3>ata1: exception Emask 0x10 SAct 0x0 SErr 0x4000000 action 0xe frozen
<3>ata1: irq_stat 0x00000040, connection status changed
<3>ata1: SError: { DevExch }

I checked the internet, some guys report a cable error, but when I boot on 
Android I get this:

sw_ahci sw_ahci.0: controller can't do PMP, turning off CAP_PMP
sw_ahci sw_ahci.0: forcing PORTS_IMPL to 0x1

Any suggestions ?
