Just wondering, Isn't NAND framework moved to Driver model and Device-tree model? In that case, these values should be obtained from DT.
Thanks and regards, Lokesh
Hi Lokesh
NAND framework doesn't seems moved to driver model so we obtained values in mem-guardian.h
Thanks and regards, Gireesh Hiremath

I am worried this is going to effect other platforms. Recently CLK support is introduced for am33 platforms. Can you use that and get clocks info from DT.
Thanks and regards, Lokesh
Hi Lokesh
I removed lcdc clock enabling code from board file and used recently added CLK & LCD driver support from am33 platforms.

Please split driver and defconfig changes. Isn't it possible to re-use drivers/bootcount/bootcount_davinci.c?
Thanks and regards, Lokesh
Hi Lokesh
Splited driver and defconfig changes.
We are using the update manager on an AM3352 where we have only the RTC Scratch registers to store the data in. Unfortunately the drivers/bootcount/bootcount_davinci.c is only handling the bootcount itself and not dealing with update_available and version. The consequence is that rollbacks could always happen, not just after an update. This can e.g. be triggered if the user tries to start up the device with a weak accu pack where the device bootloader might be executed and then the battery dies off during Linux startup. Then bootcount would be incremented, but not reset by the Linux process. If that happens several times in a row, the device will roll back, even if the update was done years ago. Other backends, like drivers/bootcount/bootcount_ext.c handle this properly, by only incrementing boot count if update_available==1. We thought of modifying bootcount_davinci.c but we concerned about backwards compatibility and breakage of other user space update managers. Therefore we think to introduce an alternative backend.
Thanks and regards, Gireesh Hiremath
