2016-07-26i2c: mvtwsi: Factor out adap parametermario.six@gdsys.cc
To be able to use the compatibility layer from the DM functions, we factor the adap parameter out of all functions, and pass the actual register base instead. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Stefan Roese <sr@denx.de>

To prepare for the DM conversion, we add a layer of compatibility functions to be used by both the legacy and the DM functions. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Stefan Roese <sr@denx.de>
2016-07-26i2c: mvtwsi: Use 'uint' instead of 'unsigned int'mario.six@gdsys.cc
Since some additional parameters will be added in the course of this patch series (especially with the addition of DM support), we replace the longer "unsigned int" declarations with "uint" declarations to keep the parameter lists more readable.

2016-07-26i2c: mvtwsi: Get rid of status parametermario.six@gdsys.cc
The twsi_stop function contains a parameter "status," which is used to pass in the current exit status of the function calling twsi_stop, and either return this status unchanged if it indicates an error, or return twsi_stop's exit status if it does not indicate an error. While not massively complicated, this adds another purpose to the twsi_stop function, which should have the sole purpose of asserting a STOP condition on the bus (and not manage the exit status of its caller). Therefore, we move the exit status management into the caller functions by introducing a "stop_status" variable and returning either the status before the twsi_stop call (kept in the "status" variable), or the status from the twsi_stop call, depending on which indicates an error.

2016-07-26i2c: mvtwsi: Eliminate flags parametermario.six@gdsys.cc
Due to breaking boots from NOR flashes, commit d6b7757 ("i2c: mvtwsi: Eliminate twsi_control_flags") removed the static global twsi_control_flags variable, which kept a set of default flags that were always or'd to the control register when writing. It was replaced with a flags parameter, which was passed around between the functions that needed it. Since the twsi_control_flags variable was used just for the purposes of a) setting the MVTWSI_CONTROL_TWSIEN on every control register write, and b) setting the MVTWSI_CONTROL_ACK from twsi_i2c_read if needed, anyway, the added overhead of another variable being passed around is no longer justified, and we are better off implementing this flag setting logic locally in the functions that actually write to the control register. Therefore, this patch sets MVTWSI_CONTROL_TWSIEN on every control register write, replaces the twsi_i2c_read's flags parameter with a ack_flag parameter, which tells the function whether to acknowledge the read or not, and removes every other instance of the flags variable. This has the added benefit that now every notion of "global default flags" is gone, and it's much easier to see which control flags are actually set at which point in time.

2016-07-25rockchip: sdram: Fix register layout for LinuxJohn Keeping
The ChromeOS kernel reads the RAM settings from PMU_SYS_REG2 and expects the bootloader to store the necessary information there. We're using the same register to pass the same information between the SPL and U-Boot but in a slightly different format. Change this to use the format expected by the Linux DMC driver so that the system doesn't hang in Linux by misconfiguring the RAM. This is almost the same as commit b5788dc ("rockchip: rk3288: correct sdram setting") which was reverted in commit b525556 ("Revert "rockchip: rk3288: correct sdram setting"") but parenthese have been added to apply the mask correctly when reading the "bw" setting and a couple of minor style issues have been fixed to keep check_patch.pl happy.
