In the document QorIQ SDK v2.0-1703 Documentation: Section 3.3.1 Customize U-Boot : The document says u-boot <machine>.conf UBOOT_CONFIG variables are to be modified as needed and then u-boot source code is modified.
Our custom board will boot from QSPI FLASH. It will have a larger FLASH than the ls1021Atwr.
When analyzing the <machine>.conf file, there are a variety of "defaults" configured. I see that several u-boot versions are built, one of which is QSPI boot.
So, my questions are:
1) Are the required modifications to u-boot source/configs already taken care of by the SDK?
2) If not, which ones require mods for a given boot device? I read in other places that the boot source when building with yacto is determined in the local.conf file, but I don't see that said in the SDK document. ... So, this is confusing.
Would you mind clarifying what needs to be done to build a QSPI boot from Nor for a ls1021a?
