The SPI NOR core will get Octal DTR in following commits. This has presented a significant challenge of keeping the SPL size in check on the x530 platform.
On a previous iteration of the series, adding a set of compile-time switches got the build working. But rebasing on the latest master breaks the build again. We are fighting a losing battle here. Every addition to either the SPI NOR core in the future, or any other core part of U-Boot will potentially lead to the SPL size going beyond the limit and the build failing.
To combat this we will have to keep adding more and more compile-time switches, increasing the complexity of the code in the process. This is not sustainable. So use tiny SPI NOR instead. It is designed with size-limited SPL binaries in mind, and will afford us more breathing room.
To enable tiny SPI NOR, CONFIG_SPI_FLASH_BAR has to be disabled.
