This reverts commit 2a5d5d27edfbdb0e02a7fcf05569f92c02ae44ee. The commit breaks uboot boot (hang in ddr init) on many PowerPC boards like P3041DS, P4080DS Signed-off-by: Biwen Li Signed-off-by: Priyanka Jain

mpc85xx: ddr: Always start DDR RAM in Self Refresh mode

2019-12-23T08:37:55Z

Some of t1042 boards fails DDR init with an Automatic calibration error every now and then. Investigations revealed that true Warm boots never failed. Warm boots has some extra steps performed, one being to start DDRC in Self Refresh and then clearing SR right after. Applying this SR method unconditionally made all our boards stable again, regardless of Cold/Warm boot. Signed-off-by: Joakim Tjernlund Signed-off-by: Priyanka Jain

boards: lx2160a: Add support of I2C driver model

2019-08-22T03:37:35Z

DM_I2C_COMPAT is a compatibility layer that allows using the non-DM I2C API when DM_I2C is used. When DM_I2C_COMPAT is not enabled for compilation, a compilation error will be generated. This patch solves the problem that the i2c-related api of the lx2160a platform does not support dm. Signed-off-by: Chuanhua Han Reviewed-by: Prabhakar Kushwaha
