Still not test on real hardware. From commit 
f022d36e8a4517b2a9d25ff2d75bd2459d0c68b1,
"
         uint    adsaddr;        /* ADMA system address register */
-       char    reserved2[160]; /* reserved */
+       char    reserved2[100]; /* reserved */
+       uint    vendorspec;     /* Vendor Specific register */
+       char    reserved3[59];  /* reserved */
         uint    hostver;        /* Host controller version register */
"
It's clear that 160 bytes does not equal with (100 + 4 + 59)bytes.
