2014-09-08net: Merge asm/fsl_enet.h into fsl_mdio.hClaudiu Manoil
fsl_enet.h defines the mapping of the usual MII management registers, which are included in the MDIO register block common to Freescale ethernet controllers. So it shouldn't depend on the CPU architecture but it should be actually part of the arch independent fsl_mdio.h. To remove the arch dependency, merge the content of asm/fsl_enet.h into fsl_mdio.h. Some files (like fm_eth.h) were simply including fsl_enet.h only for phy.h. These were updated to include phy.h instead. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com>
2014-08-01powerpc: macros for e500mc timer regs addedBoschung, Rainer
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 Signed-off-by: Rainer Boschung <rainer.boschung@keymile.com> Reviewed-by: York Sun <yorksun@freescale.com>

2014-06-05powerpc/mpc85xx: Add workaround to enable TDM on T1040Sandeep Singh
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 Signed-off-by: Sandeep Singh <Sandeep@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>

Erratum A007212 for DDR is about a runaway condition for DDR PLL oscilliator. Please refer to erratum document for detail. For this workaround to work, DDR PLL needs to be disabled in RCW. However, u-boot needs to know the expected PLL ratio. We put the ratio in a reserved field RCW[18:23]. U-boot will skip this workaround if DDR PLL ratio is set, or the reserved field is not set. Workaround for erratum A007212 applies to selected versions of B4/T4 SoCs. It is safe to apply the workaround to all versions. It is helpful for upgrading SoC without changing u-boot. In case DDR PLL is disabled by RCW (part of the erratum workaround), we need this u-boot workround to bring up DDR clock. Signed-off-by: York Sun <yorksun@freescale.com>
