I applied your patches and worked perfectly, however I've two small issues.

The first issue is that I see the following error:

    scanning bus for devices...
    ERROR: v7_dcache_inval_range - start address is not aligned - 0xfee48618
    ERROR: v7_dcache_inval_range - stop address is not aligned - 0xfee48818

The second issue, and I'm not sure if the problem should be solved at
u-boot level, is that I'm not able to access to the SATA disk at
kernel level. I meant, if I boot to the system with latest stable
u-boot the kernel recognizes the SATA disk and I'm able to mount, read
and write to the disk. If I boot using u-boot with your patches
applied the kernel doesn't recognizes the SATA disk and doesn't work.
In that case the kernel reports the following error:

     ata1: COMRESET failed (errno=-16)

Note that the kernel version that I'm using is 3.8.13 from git.ti.com.

Cheers,
