[U-Boot] [PATCH 1/4] Make pixis_set_sgmii more general to support MPC85xx boards.

[U-Boot] [PATCH 1/4] Make pixis_set_sgmii more general to support MPC85xx boards.

[Jason Jin]

From: Liu Yu <yu.liu@freescale.com>

The pixis sgmii command depend on the FPGA support on the board, some 85xx
boards support SGMII riser card but did not support this command, define
CONFIG_PIXIS_SGMII_CMD for those boards which support the sgmii command.

Not like 8544, 8572 has 4 eTsec so that the other two's pixis bits
are not supported by 8544. Therefor, define PIXIS_VSPEED2_MASK and
PIXIS_VCFGEN1_MASK in header file for both boards.

[U-Boot] [PATCH 4/4] Do not init SATA when disabled on 8536DS.

[Jason Jin]

SGMII and SATA share the serdes on MPC8536 CPU, When SATA disabled and the
driver still try to access the SATA registers, the cpu will hangup.
This patch try to fix this by reading the serdes status before the SATA
initialize.
