[U-Boot] [PATCH v2] mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTD

Wed Oct 23 07:36:52 UTC 2019

From: Frieder Schrempf <frieder.schrempf at kontron.de>

Most boards currently use SPI_FLASH_MTD only in U-Boot proper, not in
SPL. They often rely on hacks in the board header files to include
this option conditionally. To be able to fix this, we previously
introduced a separate option SPL_SPI_FLASH_MTD.

Therefore we can now adjust the Makefile and change the code in
sf_probe.c and sf_internal.h to use CONFIG_IS_ENABLED(SPI_FLASH_MTD).

We also need to move all occurences of CONFIG_SPI_FLASH_MTD from the
header files to the according defconfigs. The affected boards are
socfpga, aristainetos, cm_fx6, display5, ventana, rcar-gen2, dh_imx6
and da850evm.

We do this all in one patch to guarantee bisectibility.

This change was tested with buildman to make sure it does not
introduce any regressions by comparing the resulting binary sizes.
