Thanks Xiaowei

I have check these set of patches, it don't impact my patches, my patches implemented the ESPI DM driver of POWERPC.
But you add:
+#undef CONFIG_DM_SPI_FLASH
for SPL, Which is problematic as explained in the patch set.
Can I modify the patches like this? diff --git a/include/config_uncmd_spl.h b/include/config_uncmd_spl.h index da94b3d..c2f9735 100644 --- a/include/config_uncmd_spl.h +++ b/include/config_uncmd_spl.h @@ -15,7 +15,6 @@ #undef CONFIG_DM_GPIO #undef CONFIG_DM_I2C #undef CONFIG_DM_SPI -#undef CONFIG_DM_SPI_FLASH #endif

+/* SPI Flash Configs */ +#if defined(CONFIG_SPL_BUILD) +#undef CONFIG_DM_SPI +#undef CONFIG_DM_SPI_FLASH +#undef CONFIG_SPI_FLASH_MTD +#endif
The whole point is to avoid adding the above code.
The rationale for this can be found in the commit message: https://patchwork.ozlabs.org/patch/1146375/
Hi Lukasz, thanks for your comments, ask a question, I modify my driver like this: diff --git a/drivers/spi/fsl_espi.c b/drivers/spi/fsl_espi.c index fd5ac97..54be036 100644 --- a/drivers/spi/fsl_espi.c +++ b/drivers/spi/fsl_espi.c @@ -367,6 +367,7 @@ void espi_setup_slave(struct fsl_spi_slave *fsl) * 10), spi_freq);/* Set eSPI BRG

When I compile the driver with SPL mode, the DM or non DM mode cod will be compiled together, I think CONFIG_IS_ENABLED(DM_SPI) is 0 or 1, so the DM code or non DM code will be compiled, but not both, this make me confused, do I miss something, could you tell me the reason? Thanks a lot.
So the CONFIG_IS_ENABLED(FOO) is true if:
- The CONFIG_FOO is defined in Kconfig files (if it is defined
in ./include/configs/<board.h> then CONFIG_IS_ENABLED will return false, which is wrong).
- The CONFIG_IS_ENABLED(FOO) is true if in Kconfig you have defined
CONFIG_FOO
- CONFIG_IS_ENABLED(FOO) is true if in Kconfig you have defined
CONFIG_SPL_FOO
So the CONFIG_IS_ENABLED(FOO) shall be used in conjunction with CONFIG_DM_FOO (SPI in your case).
