Also, you want to use #if CONFIG_IS_ENABLED(...) here to guard against SPL builds too. However, I don't fully grasp why you need this patch. Please describe in your commit message what the incentive is for creating it. What errors are you trying to protect against?

Hello Takahiro, doesn't this imply that building common/spl/spl_sata.c without FAT will fail for CONFIG_SPL_SATA_SUPPORT=y (e.g. cm_t54_defconfig with FAT disabled).

Sure; See https://lists.denx.de/pipermail/u-boot/2018-August/338054.html In short, one macro definition in this file will break without CONFI_FS_FAT_*.

Yes, you're right, but this is a matter of cm_t54_defconfig. spl_sta.c uses spl_load_image_fat[_os]() which are implemented in spl_fat.c which replies on CONFIG_SPL_FAT_SUPPORT, which will in turn select CONFIG_FS_FAT. The problem is that cm_t54_defconfig doesn't enable CONFIG_SPL_FAT_SUPPORT. To fix this issue, we should add "depends on SPL_FAT_SUPPORT" to SPL_SATA_SUPPORT (and SPL_USB_SUPPORT) as well. > Did you run Travis CI on your patch series?

Therefore, I don't think we need a change Alex suggested.

So it is advisable for the submitter of the patch series to already run the same tests, especially for large changes. This will require that you have a repository on Github and authorize Travis CI to access it. Then every time you push to the repository the Travis test suite will be run. As this takes several hours I have decided to use a separate repository for Travis testing only. Best regards Heinrich
