Hi,

We have received a linux patch file “linux-3.14.27-s70gl02gs.patch.zip” from BushraH_91 on Aug 7, 2019 3:10 PM in the below discussion.

https://community.cypress.com/thread/48218?start=0&tstart=0

S70GL02GS is being detected as 128 MB on our custom board.  Towards this we have few questions on the patch file:

Is the patch applicable for Linux version 4.14?

On which version of Linux version was this patch validated?

Regards

Srinivasa

Hi Srinivasa,

in your case the ti,am3352-gpmc driver is your board driver and is probably taking care of the mapping and calling cfi_probe.

cfi_probe analyzes the provided memory window. If it finds a device and if the memory window is larger than the device size it is probing again at the address range above the first device for additional ones. So no need to call cfi_probe twice from within the board driver.

Best regards,

Gernot
