2016-12-03cmd: move CMD_PXE to KconfigYann E. MORIN
Currently, CMD_PXE is forcibly enabled in config_distro_defaults.h, so that general purpose distributions can rely on it being defined. This header is included, under conditions or not, by various archs or famillies of archs / SoCs. However, it is very possible that boards based on those SoCs will not have a physical ethernet connector at all, even if the have a MAC; for example, the Nanopi Neo AIR (sunxi H3) does not. It is also possible that network booting is absolutely not necessary for a device. However, it is not possible to disable the PXE command, as it is forcibly enabled and is non-configurable. But it turns out we already have a config option to build a distro-ready image, in the name of DISTRO_DEFAULTS. Move CMD_PXE out of the hard-coded config_distro_defaults.h into a Kconfig option, that gets selected by DISTRO_DEFAULTS when it is set. Signed-off-by: "Yann E.

A number of platforms had been using the distro default feature before it was moved to Kconfig but did not enable the new Kconfig option when it was enabled.

2016-12-02libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORYMasahiro Yamada
Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt(). It will be useful when we want to use a memory node from a kernel DTB as is, but need some fixups for Spin-Table/PSCI.

Most new systems in U-Boot these days make use of the generic "distro" framework which allows a user to have U-Boot scan for a bootable OS on all available media types.

Traditionally the DFU support is available only as part 2nd stage boot loader(u-boot) and DFU is not supported in SPL. The SPL-DFU feature is useful for boards which does not have MMC/SD, ethernet boot mechanism to boot the board and only has USB inteface. This patch add DFU support in SPL with RAM memory device support to load and execute u-boot. And then leverage full functionality DFU in u-boot to flash boot inital binary images to factory or bare-metal boards to memory devices like SPI, eMMC, MMC/SD card using USB interface.

2016-09-19Revert "Increase default of CONFIG_SYS_MALLOC_F_LEN for SPL_OF_CONTROL"Masahiro Yamada
This reverts commit 90c08d9e08c7a108ab904f3bbdeb558081757892. I took a closer look at this after the commit was applied, and found CONFIG_SYS_MALLOC_F_LEN=0x2000 was too much. 8KB memory for SPL is actually too big for some boards.

2016-08-05treewide: move CONFIG_PHYS_64BIT to KconfigMasahiro Yamada
We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so that it is always available to the build system. Otherwise we can run into cases where we have inconsistent sizes of certain attributes. Ravi Babu reported offset mismatch of struct dwc3 across files since commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t"). Since the commit, resource_addr_t points to phys_addr_t, whose size is dependent on CONFIG_PHYS_64BIT for ARM architecture. I tried my best to use "select" where possible (for example, ARMv8 architecture) because I think this kind of option is generally user- unconfigurable. However, I see some of PowerPC boards have 36BIT defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the defconfigs for such boards. CONFIG_36BIT is no longer referenced, so all of the defines were removed from CONFIG_SYS_EXTRA_OPTIONS.

DISTRO_DEFAULTS is intended to mirror / replace include/config_distro_defaults.h. The intend is for boards which include this file to select this from their Kconfig files and when moving setting to Kconfig which are #define-ed in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that boards which have selected DISTRO_DEFAULTS will keep the same configuration as before without needing any defconfig file changes. The initial list of selected things matches all settings recently removed from config_distro_defaults.h because they have been converted to Kconfig, with the exception of CMD_ELF and CMD_NET, which have a default of y, if the default of these ever changes they should be selected by DISTRO_DEFAULTS too.

malloc_simple uses a part of the stack as heap, initially it uses SYS_MALLOC_F_LEN bytes which typically is quite small as the initial stacks sits in SRAM and we do not have that much SRAM to work with. When DRAM becomes available we may switch the stack from SRAM to DRAM to give use more room. This commit adds support for also switching to a new bigger malloc_simple heap located in the new stack. Note that this requires spl_init to be called before spl_relocate_stack_gd which in practice means that spl_init must be called from board_init_f.

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.

2015-03-04arm: spl: Allow board_init_r() to run with a larger stackSimon Glass
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.

2015-02-24kconfig: switch to single .config configurationMasahiro Yamada
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 cbdd9a9737cc (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 b724bd7d6349 (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.

2015-01-29FIT: Modify option FIT_SIGNATURE in KconfigRuchika Gupta
For FIT signature based approach to work, RSA library needs to be selected. The FIT_SIGNATURE option in Kconfig is modified to automatically select RSA. Selecting RSA compiles the RSA library required for image verification.

2015-01-14Kconfig: move CONFIG_SYS_CLK_FREQ to KconfigAlexey Brodkin
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.
