fbc20aab11 powerpc/85xx: always implement the work-around for Erratum SATA_A001
On the P1022/P1013, the work-around for erratum SATA_A001 was implemented
only if U-Boot initializes SATA, but SATA is not initialized by default.  So
move the work-around to the CPU initialization function, so that it's always
executed on the SOCs that need it.

c4c9fbebae consolidate mdelay by providing a common function for all users
There are several mdelay() definitions in the driver and
board code. Remove them all and provide a common mdelay()
in lib/time.c.

007a28d54d fsl_sata: Fix compile error when CONFIG_LBA48 is not defined

is not avaible, and can't be used.

f54fe87ace 85xx/fsl-sata: Use is_serdes_configured() to determine if SATA is enabled
On the MPC85xx platform if we have SATA its connected on SERDES.
Determing if SATA is enabled via sata_initialize should not be board
specific and thus we move it out of the MPC8536DS board code.

Additionally, now that we have is_serdes_configured() we can determine
if the given SATA port is enabled and error out if its not in the
driver.

e4773debb7 fsl_sata: Add the workaround for errata SATA-A001
After power on, the SATA host controller of P1022 Rev1 is configured
in legacy mode instead of the expected enterprise mode.

Software needs to clear bit[28] of HControl register to change to
enterprise mode after bringing the host offline.

f14d81050a fsl_sata: Fix compiler warnings shown by gcc-4.4
Update fsl_sata to use common structures instead of casting
back and forth between the fsl specific ones and the common ones
(which are identical).

9810263afe sata: wait for device updating signature to host
The driver need wait for the device updating signature to host.
If we don't wait for it, the driver can not detect the device(disk)
when the system powers up.
