driver/net/fm/memac_phy: set NEG bit for external MDIOs
NEG bit default is '1' for external MDIOs as per FMAN-v3 RM, but on some platforms, e.g. T2080QDS, this bit is '0', which leads to MDIO failure on XAUI PHY, so set this bit definitely to align with the RM.

powerpc: macros for e500mc timer regs added
For e500mc cores the watchdog timer period has to be set by means of a 6bit value, that defines the bit of the timebase counter used to signal a watchdog timer exception on its 0 to 1 transition. The macro used to set the watchdog period TCR_WP, was redefined for e500mc to support 6 WP setting.
The parameter (x) given to the macro specifies the prescaling factor of the time base clock (fTB):
watchdog_period = 1/fTB * 2^x

mpc85xx/t104x: Enable L2 and CPC cache when resume
When resume from deep sleep, uboot needs to enable L2 and CPC cache, or they would be keeping unusable in kernel because kernel didn't enble or initialized them. This patch didn't change the existing L2 cache enabling code, just put them in a function.

powerpc/mpc85xx: Add workaround to enable TDM on T1040
This is a workaround for 32 bit hardware limitation of TDM. T1040 has 36 bit physical addressing, TDM DMAC register are 32 bit wide but need to store address of CCSR space which lies beyond 32 bit address range. This workaround creats a LAW to enable access of TDM DMA to CCSR by mapping CCSR to overlap with DDR. A hole of 16M is created in memory using device tree. This workaround law is set only if "tdm" is defined in hwconfig. Also disable POST tests and add LIODN for TDM

powerpc/serdes: Add the workaround for erratum A-007186
SerDes PLL is calibrated at reset. When the junction temperature delta from the time the PLL is calibrated exceeds +56C/-66C, jitter may increase and can cause PLL to unlock.
This workaround overwrite the SerDes registers with new values, to calibrate SerDes registers. These values are known to work fine for all temperature ranges.
This workaround is valid for B4, T4 and T2 platforms, so added in their config.

powerpc/mpc85xx: Add workaround for DDR erratum A004508
When the DDR controller is initialized below a junction temperature of 0°C and then operated above a junction temperature of 65°C, the DDR controller may cause receive data errors, resulting ECC errors and/or corrupted data. This erratum applies to the following SoCs and their variants: MPC8536, MPC8569, MPC8572, P1010, P1020, P1021, P1022, P1023, P2020.
