[U-Boot] [PATCH 0/7] ARM: OMAP4+: Cleanup clocks, control and emif code
This series is intended to cleanup code which is duplicated across soc specific files. This is accomplished by moving soc specifc data to one place and having the code common. This helps in avoiding un necessary cpu checks and minimal code addition for future socs.
Tested this on OMAP5 ES1.0, OMAP4460 Panda boards and verified MAKEALL for all armv7 boards.
Lokesh Vutla (4): ARM: OMAP4+: emif: Detect SDRAM from SDRAM config register ARM: OMAP4+: Cleanup emif specific files ARM: OMAP4+: Make control module register structure generic ARM: OMAP5: Clean up iosettings code
R Sricharan (3): ARM: OMAP4+: Change the PRCM structure prototype common for all Socs ARM: OMAP4+: Cleanup the clocks layer ARM: OMAP4+: Clean up the pmic code

Now SDRAM initialization is done on the basis of omap revision. Instead this should be done on basis of SDRAM type read from EMIF_SDRAM_CONFIG register. This will be helpful to avoid unnessecary cpu checks for new boards

Does this mean the ROM is already doing some basic EMIF programming here? I swear I looked down this path before, when I wanted to share this code with am33xx and the problem is that while the registers aren't reset on warm boot, on cold boot they always come up in a default value, for both DDR2 and DDR3.
Or are you able to get by as the platforms come up with different default values?

Not the ROMCODE, the default value for SDRAM_CONFIG register is exported from control module register based on efuse settings. We did see that this default value was correct depending upon LPDDR2 or DDR3 in the case of OMAP.
So does this mean that am3xx did not have the logic to load this register dynamically based on efuse settings ? If that is the only exception, then we can hardcode the register during startup only in that case. Except for this, where you able to use the emif-common driver in your case ?

OK, good.

In my initial testing, it was not being setup correctly. I think it was between that, and trying to abstract out further the PM-related changes there wasn't much common EMIF code left, so I set the project aside at the time. I'll try and take another whack at it as I know someone is adding ti814x support currently and did find a good match-up with this EMIF code rather than the am33xx version, so maybe that will help me to see what's going on.
And with all of that: Reviewed-by: Tom Rini trini@ti.com

The current PRCM structure prototype directly matches the hardware register layout. So there is a need to change this for every new silicon revision which has register space changes.
Avoiding this by making the prototye generic and populating the register addresses seperately for all Socs.

The current PRCM structure prototype directly matches the hardware register layout. So there is a need to change this for every new silicon revision which has register space changes.
Avoiding this by making the prototye generic and populating the register addresses seperately for all Socs.

These two are missing license information, please fix.
Otherwise, I like the concept and I think it all looks fine. We stay about the same, binary size wise with all of this, correct?

Sorry for missing this. Will send a V2

Yes,i checked this after the change.The spl size for OMAP4 is still 29KB and less than the limit (32KB). The size is never an issue with OMAP5
Regards, Sricharan
Currently there is quite a lot of code which is duplicated in the clocks code for OMAP 4 and 5 Socs. Avoiding this here by moving the clocks data to a SOC specific place and the sharing the common code.
This helps in addition of a new Soc with minimal changes.

Currently there is quite a lot of code which is duplicated in the clocks code for OMAP 4 and 5 Socs. Avoiding this here by moving the clocks data to a SOC specific place and the sharing the common code.
This helps in addition of a new Soc with minimal changes.

The pmic code is duplicated for OMAP 4 and 5. Instead move the data to Soc specific place and share the code.

Removing the duplicated code in ddr3 initialization. Also creating structure for lpddr2 mode registers to avoid unnessecary revision checks.
These change reduces code addition for future Socs.

A seperate omap_sys_ctrl_regs structure is defined for omap4 & 5. If there is any change in control module for any of the ES versions, a new structure needs to be created. In order to remove this dependency, making the register structure generic for all the omap4+ boards.

A seperate omap_sys_ctrl_regs structure is defined for omap4 & 5. If there is any change in control module for any of the ES versions, a new structure needs to be created. In order to remove this dependency, making the register structure generic for all the omap4+ boards.

There is some code duplication in the ddr io settings code. This is avoided by moving the data to a Soc specific place and letting the code generic.
This avoids unnessecary code addition for future socs.
