2017-10-02x86: Use asm-generic/io.hPaul Burton
Convert the x86 architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for x86 this is primarily a matter of moving code. This has only been build-tested, feedback from architecture maintainers is welcome.

With bootstage we need access to the timer before driver model is set up. To handle this, put the required state in global_data and provide a new function to set up the device, separate from the driver's probe() method. This will be used by the 'early' timer also.

It was noticed a few times, that the reboot from Linux (reboot command) is different from the reboot (reset command) under U-Boot. The U-Boot version does seem to reset the board more deeply (PCI cards etc) than the Linux reboot. This is actually caused by missing full reset bit in the reset register value in the ACPI FADT table.

2017-08-24x86: fsp: Configure SPI opcode registers before SPI is locked downBin Meng
Some Intel FSP (like Braswell) does SPI lock-down during the call to fsp_notify(INIT_PHASE_BOOT). But before SPI lock-down is done, it's bootloader's responsibility to configure the SPI controller's opcode registers properly otherwise SPI controller driver doesn't know how to communicate with the SPI flash device. This introduces a Kconfig option CONFIG_FSP_LOCKDOWN_SPI for such FSPs. When it is on, U-Boot will configure the SPI opcode registers before the lock-down.

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

64-bit U-Boot image is a combination of 32-bit U-Boot (SPL) plus 64-bit U-Boot (proper). For the U-Boot proper, it has be compiled to 64-bit object codes. Attempting to use a toolchain to compile 64-bit U-Boot for qemu-x86_64, like kernel.org 4.9 i386-linux-gcc, fails with the following errors: arch/x86/cpu/intel_common/microcode.c:79:2: error: PIC register clobbered by 'ebx' in 'asm' The issue is because toolchain is preconfigured to generate code for the 32-bit architecture (i386), and currently '-m64' is missing in the makefile fragment. Using kernel.org 4.9 x86_64-linux-gcc works out of the box, since it is preconfigured to generate 64-bit codes. When compiling U-Boot SPL, '-m32' is passed to the toolchain, no mater 32-bit (i386-linux-) or 64-bit (x86_64-linux) the toolchain is preconfigured to generate.
