[U-Boot] [PATCH 1/3] mtd: spi: Add a new option SPL_SPI_FLASH_MTD to Kconfig

[Schrempf Frieder]

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

To allow SPI_FLASH_MTD being enabled separately in SPL we add a new
option. The only user currently is the stm32mp15_basic board.

[U-Boot] [PATCH 2/3] stm32mp1: configs: Add CONFIG_SPL_SPI_FLASH_MTD

[Schrempf Frieder]

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

As SPI_FLASH_MTD is used in SPL and U-Boot proper, we enable both,
now that a separate option for SPL was introduced.

Yes, this is unrelated, but that's what 'menuconfig' and 'savedefconfig' 
gave me as output. So I would think it's ok. If you don't think so, feel 
free to remove this change or let me know if I should remove it.

In patchwork all three patches of this series are marked with "Changes

Thought you might drop that unrelated change and send next version,
but anyway I have changed and

I have asked you to "let me know if I should remove it" above and you 
didn't do so. Therefore I assumed you do it yourself, or you apply it as is.

[U-Boot] [PATCH 3/3] mtd: spi: Clean up usage of CONFIG_SPI_FLASH_MTD

[Schrempf Frieder]

From: Frieder Schrempf <frieder.schrempf@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.

I don't know much about the U-Boot release cycle, so maybe these are 
stupid questions.

Jagan, I saw that these 3 patches are assigned to you. When will you 
pick them? For the current release, or the next one?

Do we still need an ack for patch 2/3 from the stm32mp maintainers?

Thanks,
Frieder

These ifdef changes look unrelated wrt actual patch. any comments?

Also please rebase and send this patch, rest look fine for me.

No, they are not unrelated. This is the actual reason for having this 
patch after all. We want to be able to enable/disable the code for 
CONFIG_SPI_FLASH_MTD per build target (SPL, U-Boot proper).
These changes need to be done in a single patch together with the 
defconfig and Makefile changes to sustain bisectibility.

Ok, I will rebase on current master and send a v2.

The spi Kconfig code is so convoluted, that we shall try to do it in a
single patch (as was done here).

Otherwise we will end up with not bisectable code.

No, "#ifdef CONFIG_FOO" is definitely not the same as "#if 
CONFIG_IS_ENABLED(FOO)". Please have a look at the definition of 
CONFIG_IS_ENABLED: [1].

"CONFIG_IS_ENABLED(FOO)" will resolve to 1 if CONFIG_SPL_FOO and 
CONFIG_SPL_BUILD are defined.

"#ifdef CONFIG_FOO" will only resolve to 1 if CONFIG_FOO is defined.
