From: Alif Zakuan Yuslaimi<[email protected]>This patch set updates the boot support for the Altera SoCFPGA Gen5/Arria10 platform in U-Boot. The changes include: 1. Update MMU/dcache setup across Gen5/Arria10 using common driver 2. Add ECC scrubbing support for Gen5/Arria10 3. Add DRAM size checking for Gen5/Arria10 4. Assign unit address to memory node in common SoCFPGA device tree file This patch set has been tested on CycloneV devkit with SDMMC boot and RAM boot (TFTP & ARM DS debugger).

I will need to drop these patches (1/5, 2/5, 3/5) for now as it causes the U-Boot SPL file size to exceed the limit on several Cyclone V variant defconfigs (see CI failure: https://source.denx.de/u-boot/custodians/u-boot-socfpga/-/jobs/1379031).
Please consider restructuring the changes so that Arria 10 and Cyclone V are handled separately. Arria 10 has a larger OCRAM footprint, while Cyclone V is much more constrained.
The SPL size overflow on certain Cyclone V boards must be properly resolved before we can take this upstream.
Also, please make sure to run the pipeline tests and confirm they pass before resubmitting the patches upstream.
Thanks for your understanding, and please resend once the Cyclone V size issue has been properly addressed and the pipeline is clean.
Best regards, Tien Fong
