Hello, I'm working on a custom board with a Socfpga Altera Arria10 on it with a Micron Serial Nor Flash memory MT25QU01GBBB.
Currently, the Uboot 2020.04 I'm using works with one lane of QSPI data transfer with the Micron memory unit; how can I make it work with four lanes?
I can't find how I can configure it to work this way in the device tree. Also, in the Cadence Qspi driver, I can't find how to change the number of lanes to work with.
I'm working in Altera Environment 20.1.
Any help applaying this change would help.
Thanks in advance, Yoel

Hi Yoels,
Do consider using the latest Uboot for your Arria10 development. Referring to the get Uboot section:

Can search the related device tree enablement in the uboot source code, example socfpga_arria10 related:
You can check with Micron on how their particular device to be enabled as they have tested it for working:
