[PATCH v7 05/21] arm: mvebu: x530: Use tiny SPI NOR

[Pratyush Yadav]

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.
