powerpc/mpc85xx: Add support for single source clocking

2014-01-02T22:10:13Z

Single-source clocking is new feature introduced in T1040. In this mode, a single differential clock is supplied to the DIFF_SYSCLK_P/N inputs to the processor, which in turn is used to supply clocks to the sysclock, ddrclock and usbclock. So, both ddrclock and syclock are driven by same differential sysclock in single-source clocking mode whereas in normal clocking mode, generally separate DDRCLK and SYSCLK pins provides reference clock for sysclock and ddrclock DDR_REFCLK_SEL rcw bit is used to determine DDR clock source -If DDR_REFCLK_SEL rcw bit is 0, then DDR PLLs are driven in normal clocking mode by DDR_Reference clock -If DDR_REFCLK_SEL rcw bit is 1, then DDR PLLs are driven in single source clocking mode by DIFF_SYSCLK Add code to determine ddrclock based on DDR_REFCLK_SEL rcw bit.

powerpc/mpc8349: Use generic mpc85xx DDR driver

2013-12-04T22:55:05Z

MPC8349 has been using mpc85xx DDR driver through a symbolic link to mpc85xx_ddr_gen2.c. After consolidating the drivers to a single set under driver/ddr/fsl/, the link is replaced by referring driver directly. We now can simply enable the macro and use the driver. Other mpc83xx SoCs still use their own driver. Signed-off-by: York Sun

T4240: Address T4240/T4160 Rev2.0 DDR clock change

2013-12-04T22:54:42Z

MEM_PLL_RAT on T4240/T4160 Rev2.0 uses a value which is half of Rev1.0. It's 12 in Rev1.0, for Rev2.0 it uses 6. Signed-off-by: Roy Zang Signed-off-by: Shaohui Xie Acked-by: York Sun

powerpc/corenet: CPC1 speculation disable

2013-12-04T22:54:10Z

In PBL RAMBOOT(SPI/SD/NAND boot) mode, CPC1 used as SRAM, should disable CPC1 speculation and keep it till relocation. Otherwise, speculation transactions will go to DDR controller, it will cause problem. Signed-off-by: Dave Liu Signed-off-by: Shaohui Xie Acked-by: York Sun
