This commit introduces new config: CONFIG_SYS_MALLOC_CLEAR_ON_INIT. This config is an expert option and is enabled by default. The all amount of memory reserved for the malloc, is by default set to zero in mem_malloc_init(). When the malloc reserved memory exceeds few MiB, then the boot process can slow down. So disabling this config, is an expert option to reduce the boot time, and can be disabled by Kconfig. Note: After disable this option, only calloc() will return the pointer to the zeroed memory area. Previously, without this option, the memory pointed to untouched malloc memory region, was filled with zeros. So it means, that code with malloc() calls should be reexamined.

At present SPL uses a single stack, either CONFIG_SPL_STACK or CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and environment) require a lot of stack, some boards set CONFIG_SPL_STACK to point into SDRAM. They then set up SDRAM very early, before board_init_f(), so that the larger stack can be used. This is an abuse of lowlevel_init(). That function should only be used for essential start-up code which cannot be delayed. An example of a valid use is when only part of the SPL code is visible/executable, and the SoC must be set up so that board_init_f() can be reached. It should not be used for SDRAM init, console init, etc. Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new address before board_init_r() is called in SPL. The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

When Kconfig for U-boot was examined, one of the biggest issues was how to support multiple images (Normal, SPL, TPL). There were actually two options, "single .config" and "multiple .config". After some discussions and thought experiments, I chose the latter, i.e. to create ".config", "spl/.config", "tpl/.config" for Normal, SPL, TPL, respectively. It is true that the "multiple .config" strategy provided us the maximum flexibility and helped to avoid duplicating CONFIGs among Normal, SPL, TPL, but I have noticed some fatal problems: [1] It is impossible to share CONFIG options across the images. If you change the configuration of Main image, you often have to adjust some SPL configurations correspondingly. Currently, we cannot handle the dependencies between them. It means one of the biggest advantages of Kconfig is lost. [2] It is too painful to change both ".config" and "spl/.config". Sunxi guys started to work around this problem by creating a new configuration target. Commit cbdd9a97 (sunxi: kconfig: Add %_felconfig rule to enable FEL build of sunxi platforms.) added "make *_felconfig" to enable CONFIG_SPL_FEL on both images. Changing the configuration of multiple images in one command is a generic demand. The current implementation cannot propose any good solution about this. [3] Kconfig files are getting ugly and difficult to understand. Commit b724bd7d (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files. [4] The build system got more complicated than it should be. To adjust Linux-originated Kconfig to U-Boot, the helper script "scripts/multiconfig.sh" was introduced. Writing a complicated text processor is a shell script sometimes caused problems. Now I believe the "single .config" will serve us better. With it, all the problems above would go away. Instead, we will have to add some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM, but we will not have much. Anyway, this is what we do now in scripts/Makefile.spl. I admit my mistake with my apology and this commit switches to the single .config configuration. It is not so difficult to do that: - Remove unnecessary processings from scripts/multiconfig.sh This file will remain for a while to support the current defconfig format. It will be removed after more cleanups are done. - Adjust some makefiles and Kconfigs - Add some entries to include/config_uncmd_spl.h and the new file scripts/Makefile.uncmd_spl. Some CONFIG options that are not supported on SPL must be disabled because one .config is shared between SPL and U-Boot proper going forward. I know this is not a beautiful solution and I think we can do better, but let's see how much we will have to describe them. - update doc/README.kconfig More cleaning up patches will follow this.

At present defaults in arch-specific Kconfig files are ignored if the top-level item comes ahead of it in include order. This means that it is not possible to have a U-Boot default that architectures and boards can override. This does not seem very useful. Move the include earlier to support this.

It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig" instead of "include/configs/xxx.h" because then header will be reusable across boards with different CPU clocks. Also this nice to have an ability for end user to tune this value himself via "menuconfig". For now I'm only applying this change to all ARC configs because otherwise scope of change will be huge.

CONFIG_DEFCONFIG_LIST specifies the default defconfig. It is used by "make savedefconfig" when .config is missing. But that's it. I could not find other useful cases.
