kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

default X86_RUN_32BIT
help
U-Boot can be built as a 32-bit binary which runs in 32-bit mode
even on 64-bit machines. In this case SPL is not used, and U-Boot
runs directly from the reset vector (via 16-bit start-up).
Alternatively it can be run as a 64-bit binary, thus requiring a
64-bit machine. In this case SPL runs in 32-bit mode (via 16-bit
start-up) then jumps to U-Boot in 64-bit mode.
For now, 32-bit mode is recommended, as 64-bit is still
experimental and is missing a lot of features.
config X86_RUN_32BIT
bool "32-bit"
help
Build U-Boot as a 32-bit binary with no SPL. This is the currently
supported normal setup. U-Boot will stay in 32-bit mode even on
64-bit machines. When booting a 64-bit kernel, U-Boot will switch
to 64-bit just before starting the kernel. Only the bottom 4GB of
memory can be accessed through normal means, although
arch_phys_memset() can be used for basic access to other memory.

Build U-Boot as a 64-bit binary with a 32-bit SPL. This is

mode and jumps to U-Boot proper.

x86: ivybridge: Implement SDRAM init Implement SDRAM init using the Memory Reference Code (mrc.bin) provided in the board directory and the SDRAM SPD information in the device tree. This also needs the Intel Management Engine (me.bin) to work. Binary blobs everywhere: so far we have MRC, ME and microcode. SDRAM init works by setting up various parameters and calling the MRC. This in turn does some sort of magic to work out how much memory there is and the timing parameters to use. It also sets up the DRAM controllers. When the MRC returns, we use the information it provides to map out the available memory in U-Boot. U-Boot normally moves itself to the top of RAM. On x86 the RAM is not generally contiguous, and anyway some RAM may be above 4GB which doesn't work in 32-bit mode. So we relocate to the top of the largest block of RAM we can find below 4GB. Memory above 4GB is accessible with special functions (see physmem). It would be possible to build U-Boot in 64-bit mode but this wouldn't necessarily provide any more memory, since the largest block is often below 4GB. Anyway U-Boot doesn't need huge amounts of memory - even a very large ramdisk seldom exceeds 100-200MB. U-Boot has support for booting 64-bit kernels directly so this does not pose a limitation in that area. Also there are probably parts of U-Boot that will not work correctly in 64-bit mode. The MRC is one. There is some work remaining in this area. Since memory init is very slow (over 500ms) it is possible to save the parameters in SPI flash to speed it up next time. Suspend/resume support is not fully implemented, or at least it is not efficient. With this patch, link boots to a prompt. Signed-off-by: Simon Glass <sjg@chromium.org>

pylibfdt: compile pylibfdt only when dtoc/binman is necessary Currently, pylibfdt is always compiled if swig is installed on your machine. It is really annoying because most of targets (excepts x86, sunxi, rockchip) do not use dtoc or binman. "checkbinman" and "checkdtoc" are wrong. It is odd that the final build stage checks if we have built necessary tools. If your platform depends on dtoc/binman, you must be able to build pylibfdt. If swig is not installed, it should fail immediately. I added PYLIBFDT, DTOC, BINMAN entries to Kconfig. They should be property select:ed by platforms that need them.

The Slim Bootloader is designed with multi-stage architecture for the execution from reset vector to OS booting, and supports QEMU, Apollolake, Whiskeylake and Coffeelake platforms consuming Intel FSP (https://github.com/IntelFsp) for silicon initialization including CAR and memory initialization. The Slim Bootloader generates new HOB (Hand Off Block) which are serial port info, memory map info, performance data info and so on, and passes it to a Payload. U-Boot as a payload will use these HOB information for basic initialization such as serial console.

For example some rockchip boards can also boot from SPI flash. Also, at least on x86, binary blobs are sadly quite common. It is not possible to build a functional image without them, and U-Boot needs to know this at build time. Introduce a new CONFIG_HAS_ROM option which selects whether u-boot.rom is built and a new CONFIG_ROM_NEEDS_BLOBS option to indicate whether binary blobs are also needed. If they are not needed, it is safe to build the ROM always. Otherwise we still require the BUILD_ROM environment variable.

x86: make the LAPIC / IOAPIC construct switchable with Kconfig There are still systems running which do not have any LAPIC or even IOAPIC. Responsible MSRs for those do not exist and the systems are crashing on trying to setup LAPIC. This commit makes the APIC stuff able to switch off for those boards which dont' have an LAPIC / IOAPIC.

The (A)dvanced (P)rogrammable (I)nterrupt (C)ontroller is responsible
for catching interrupts and distributing them to one or more CPU
cores. In most cases there are some LAPICs (local) for each core and
one I/O APIC. This conjunction is found on most modern x86 systems.

x86: Support booting SeaBIOS SeaBIOS is an open source implementation of a 16-bit x86 BIOS. It can run in an emulator or natively on x86 hardware with the use of coreboot. With SeaBIOS's help, we can boot some OSes that require 16-bit BIOS services like Windows/DOS. As U-Boot, we have to manually create a table where SeaBIOS gets system information (eg: E820) from. The table unfortunately has to follow the coreboot table format as SeaBIOS currently supports booting as a coreboot payload.

help
SeaBIOS is an open source implementation of a 16-bit X86 BIOS.
It can run in an emulator or natively on X86 hardware with the use
of coreboot/U-Boot. By turning on this option, U-Boot prepares
all the configuration tables that are necessary to boot SeaBIOS.
Check http://www.seabios.org/SeaBIOS for details.
x86: Prepare configuration tables in dedicated high memory region Currently when CONFIG_SEABIOS is on, U-Boot allocates configuration tables via normal malloc(). To simplify, use a dedicated memory region which is reserved on the stack before relocation for this purpose. Add functions for reserve and malloc.

help
SeaBIOS itself resides in E seg and F seg, where U-Boot puts all
configuration tables like PIRQ/MP/ACPI. To avoid conflicts, U-Boot
puts a copy of configuration tables in high memory region which
is reserved on the stack before relocation. The region size is
determined by this option.
Increse it if the default size does not fit the board's needs.
This is most likely due to a large ACPI DSDT table is used.

kconfig: add board Kconfig and defconfig files This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.
