This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option.
Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif
in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig.
The goal of this patch:
Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver.
Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA).
In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c):
- U-Boot proper driver supporting DT/DTS
- U-Boot proper driver without DT/DTS support (deprecated)
- SPL driver without DT/DTS support
- SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS)
- SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support).
Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL.
This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

Sorry I didn't bisect down to which part of the series is doing this, but I see problems with: ls1046ardb_sdcard ls1046ardb_qspi_spl ls1043ardb_nand ls1046aqds_tfa ls1046aq ds_nand ls1046ardb_qspi ls1046aqds_sdcard_ifc ls1046aqds_SECURE_BOOT ls1046aqds_sdcard_qspi ls1 046aqds_qspi ls1043ardb_sdcard ls1043aqds_sdcard_ifc ls1046ardb_tfa ls1046ardb_tfa_SECURE_BOOT ls1043aqds_nand ls1046aqds_lpuart ls1046ardb_emmc ls1046aqds_tfa_SECURE_BOOT ls1046afrwy_tfa ls 1046aqds ls1043ardb_nand_SECURE_BOOT ls1046ardb_qspi_SECURE_BOOT ls1043aqds_sdcard_qspi
Some of which are dependency problems about SPL/SPL_DM.

which I think means a few conversions weren't right.
