2020-08-27env: Kconfig: Add missing dependency for ENV_IS_IN_EXT4Michal Simek
ENV_IS_IN_EXT4 also need to enable FS_EXT4 which is not covered in Kconfig.

This option marks any U-Boot variable which does not have explicit 'w' writeable flag set as read-only. This way the environment can be locked down and only variables explicitly configured to be writeable can ever be changed by either 'env import', 'env set' or loading user environment from environment storage.

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski
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.

2020-05-08env/sf.c: honour CONFIG_SPL_SAVEENVRasmus Villemoes
Deciding whether to compile the env_sf_save() function based solely on CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build warning in case CONFIG_CMD_SAVEENV=n (because the initialization of the .save member is guarded by CONFIG_CMD_SAVEENV, while the env_sf_save() function is built if !CONFIG_SPL_BUILD - and even without the CONFIG_CMD_SAVEENV guard, the env_save_ptr() macro would just expand to NULL, with no reference to env_sf_save visible to the compiler). And for SPL, when one selects CONFIG_SPL_SAVEENV, one obviously expects to actually be able to save the environment. The compiler warning can be fixed by using a "<something> ? env_sf_save : NULL" construction instead of a macro that just eats its argument and expands to NULL. That way, if <something> is false, env_sf_save gets eliminated as dead code, but the compiler still sees the reference to it. For <something>, we can use CONFIG_IS_ENABLED(SAVEENV), which is true precisely: - For U-Boot proper, when CONFIG_CMD_SAVEENV is set (because CONFIG_SAVEENV is a hidden config symbol that gets set if and only if CONFIG_CMD_SAVEENV is set). - For SPL, when CONFIG_SPL_SAVEENV is set. As a bonus, this also removes quite a few preprocessor conditionals. This has been run-time tested on a mpc8309-derived board to verify that saving the environment does indeed work in SPL with these patches applied.

Deciding whether to compile the env_sf_save() function based solely on CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build warning in case CONFIG_CMD_SAVEENV=n (because the env_save_ptr() macro causes the function to indeed not be referenced anywhere).

2020-04-24env/ext4.c: remove CONFIG_CMD_SAVEENV ifdefRasmus Villemoes
Removing this ifdef/endif pair yields a "defined but unused warning" for CONFIG_CMD_SAVEENV=n, but that vanishes if we use the ENV_SAVE_PTR macro instead. This gives slightly better compile testing, and moreover, it's possible to have CONFIG_CMD_SAVEENV=n CONFIG_SPL_SAVEENV=y SPL_ENV_IS_IN_EXT4=y in which case env_ext4_save would erroneously not be compiled in.

2020-04-24env: add SAVEENV as an alias of the CMD_SAVEENV symbolRasmus Villemoes
Currently, testing whether to compile in support for saving the environment is a bit awkward when one needs to take SPL_SAVEENV into account, and quite a few storage drivers currently do not honour SPL_SAVEENV. To make it a bit easier to decide whether environment saving should be enabled, introduce SAVEENV as an alias for the CMD_SAVEENV symbol. Then one can simply use CONFIG_IS_ENABLED(SAVEENV) Signed-off-by: Rasmus Villemoes <rasmus.villemoes@prevas.dk>
2020-04-24make env_entry::callback conditional on !CONFIG_SPL_BUILDRasmus Villemoes
The callback member of struct env_entry is always NULL for an SPL build. Removing it thus saves a bit of run-time memory in the SPL (when CONFIG_SPL_ENV_SUPPORT=y) since struct env_entry is embedded in struct env_entry_node - i.e. about 2KB for the normal case of 512+change hash table entries. Two small fixups are needed for this, all other references to the callback member are already under !CONFIG_SPL_BUILD: Don't initialize .callback in set_flags() - hsearch_r doesn't use that value anyway. And make env_callback_init() initialize ->callback to NULL for a new entry instead of relying on an unused or deleted entry having NULL in ->callback.

2020-04-24env: remove callback.o for an SPL buildRasmus Villemoes
env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK): * For SPL these are silently dropped to reduce code size, since environment * callbacks are not supported with SPL. So env_callback_init() does a lot of work to not find anything in the guaranteed empty env_clbk list. Drop callback.o entirely from the link and stub out the only public function defined in callback.o. This cuts about 600 bytes from the SPL on my ppc build.
