2019-06-10spi: mpc8xxx: Rename variableMario Six
The variable "char_size" holds the number of bits to be transferred in the current loop iteration. A better name would be "xfer_bitlen", which we rename this variable to. Signed-off-by: Mario Six <mario.six@gdsys.cc> Acked-by: Jagan Teki <jagan@amarulasolutions.com>
2019-06-10spi: mpc8xxx: Make code more readableMario Six
Introduce the to_prescale_mod and set_char_len inline functions to make the code more readable. Note that the added "if (bitlen > 16)" check does not change the semantics of the current code, and hence only preserves the current error (this will be fixed in a later patch in the series).

2019-06-10spi: mpc8xxx: Reduce scope of loop variablesMario Six
The transmission loop starts with setting some variables, which are only used inside the loop. Reduce the scope to the loop to make the declaration and initialization of these variables coincide. In the case of char_size this also always initializes the variable immediately with the final value actually used in the loop (instead of the placeholder value 32).

2019-06-10spi: mpc8xxx: Simplify logic a bitMario Six
We do nothing in the loop if the "not empty" event was not detected. To simplify the logic, check if this is the case, and skip the execution of the loop early to reduce the nesting level and flag checking.

2019-06-10spi: mpc8xxx: Get rid of is_readMario Six
Get rid of the is_read variable, and just keep the state of the "not empty" and "not full" events in two boolean variables within the loop body. Signed-off-by: Mario Six <mario.six@gdsys.cc> Acked-by: Jagan Teki <jagan@amarulasolutions.com>
2019-06-10spi: mpc8xxx: Simplify ifMario Six
Instead of having a nested if block, just have two branches within the overarching if block to eliminate one nesting level. Signed-off-by: Mario Six <mario.six@gdsys.cc> Acked-by: Jagan Teki <jagan@amarulasolutions.com>

2019-06-06mtd: Fix get_mtdparts()Patrice Chotard
When ENV_IS_IN_UBI is enable, get_mtdparts is called before relocation. During first get_mtdparts() call, mtdparts is not available in environment, it can be retrieved by calling board_mtdparts_default(), but following env_set() do nothing as we are before relocation. Finally mtdparts is still not available in environment. At second get_mtdparts() call, use_defaults is false, but mtdparts is still not in environment and is NULL. Remove use_defaults bool, only mtdparts criteria is useful.

2019-06-01dm: net: macb: Implement link speed change callbackBin Meng
At present the link speed change callback is a nop. According to macb device tree bindings, an optional "tx_clk" is used to clock the ethernet controller's TX_CLK under different link speed. In 10/100 MII mode, transmit logic must be clocked from a free running clock generated by the external PHY. In gigabit GMII mode, the controller, not the external PHY, must generate the 125 MHz transmit clock towards the PHY.
