[U-Boot] [PATCH 1/4] ppc: Split MPC83xx SERDES code from MPC85xx/MPC86xx/QorIQ

[U-Boot] [PATCH 1/4] ppc: Split MPC83xx SERDES code from MPC85xx/MPC86xx/QorIQ

[Kumar Gala]

The MPC83xx SERDES control is different from the other FSL PPC chips.
For now lets split it out so we can standardize on interfaces for
determining of a device on SERDES is configured.

[U-Boot] [PATCH 2/4] 85xx: Add is_serdes_configured() support to MPC8536 SERDES

[Kumar Gala]

Add the ability to determine if a given IP block connected on SERDES is
configured.  This is useful for things like PCIe and SRIO since they are
only ever connected on SERDES.

[U-Boot] [PATCH 3/4] 85xx/mpc8536ds: Use is_serdes_configured() to determine of PCIe enabled

[Kumar Gala]

The new is_serdes_configured covers a broader range of devices than the
PCI specific code.  Use it instead as we convert away from the
is_fsl_pci_cfg() code.

[U-Boot] [PATCH 4/4] 85xx/fsl-sata: Use is_serdes_configured() to determine if SATA is enabled

[Kumar Gala]

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.

The header change is already in the P2020 serdes patch series.  Would
you help to merge that patch series and deal with the conflict also?
