2018-10-22imx: mx7: avoid some initialization if low level is skippedRui Miguel Silva
We can have the case where u-boot is launched after some other low level enabler, like for example when u-boot runs after arm-trusted-firmware and/or optee. So, because of that we may need to jump the initialization of some IP blocks even because we may no longer have the permission for that. So, if the config option to skip low level init is set disable also timer, board and csu initialization.

2018-10-22power: Add power domain driver for i.MX8Peng Fan
Add the power domain DM driver for i.MX8, that it depends on the DTB power domain trees to generate the power domain provider devices. Users need to add power domain trees with property "compatible = "nxp,imx8-pd";" When power on a PD device, the driver will power on its ancestor PD devices in power domain tree. When power off a PD device, the driver will check its child PD devices first. Only if all child PD devices are off, then power off the current PD device. Then the driver checks sibling PD devices. If sibling PD devices are off, then it will power off parent PD device. There is no counter maintained in this driver, but a state to hold current on/off state. So the request and free functions are empty. The power domain implementation in i.MX8 DTB set the "#power-domain-cells" to 0, so there is no ID binding with each PD device. We don't use "id" variable in struct power_domain. At the same time, we have to set of_xlate to empty to bypass standard of_xlate in uclass driver.

2018-10-22x86: Fix the mystery of printch() during 64-bit bootBin Meng
At present in arch_setup_gd() it calls printch(' ') at the end which has been a mystery for a long time as without such call the 64-bit U-Boot just does not boot at all. In fact this is due to the bug that board_init_f() was called with boot_flags not being set. Hence whatever value being there in the rdi register becomes the boot_flags if without such magic call. With a printch(' ') call the rdi register is initialized as 0x20 and this value seems to be sane enough for the whole boot process.

2018-10-22x86: put global data pointer into the .data sectionHeinrich Schuchardt
On x86_64 the field global_data_ptr is assigned before relocation. As sections for uninitialized global data (.bss) overlap with the relocation sections (.rela) this destroys the relocation table and leads to spurious errors. Initialization forces the global_data_ptr into a section for initialized global data (.data) which cannot overlap any .rela section.

2018-10-22x86: Ensure no instruction sets of MMX/SSE are generated in 64-bit buildBin Meng
With the '-march=core2' fix, it seems that we have some luck that the 64-bit U-Boot boots again. However if we examine the disassembly codes there are still SSE instructions elsewhere which means passing cpu type to GCC is not enough to prevent it from generating these instructions. A simple test case is doing a 'bootefi selftest' from the U-Boot shell and it leads to a reset too. The 'bootefi selftest' reset is even seen with the image created by the relative older GCC 5.4.0, the one shipped by Ubuntu 16.04. The reset actually originates from undefined instruction exception caused by these SSE instructions. To keep U-Boot as a bootloader as simple as possible, we don't want to handle such advanced SIMD stuff. To make sure no MMX/SSE instruction sets are generated, tell GCC not to do this. Note AVX is out of the question as CORE2 is old enough to support AVX yet.

2018-10-22x86: Specify -march=core2 to build 64-bit U-Boot properBin Meng
With newer kernel.org GCC (7.3.0 or 8.1.0), the u-boot.rom image built for qemu-x86_64 target does not boot. It keeps resetting soon after the 32-bit SPL jumps to 64-bit proper. Debugging shows that the reset happens inside env_callback_init(). 000000000113dd85 <env_callback_init>: 113dd85: 41 54 push %r12 113dd87: 55 push %rbp 113dd88: 31 c0 xor %eax,%eax 113dd8a: 53 push %rbx 113dd8b: 0f 57 c0 xorps %xmm0,%xmm0 Executing "xorps %xmm0,%xmm0" causes CPU to immediately reset. However older GCC like 5.4.0 (the one shipped by Ubuntu 16.04) does not generate such instructions that utilizes SSE for this function - env_callback_init() and U-Boot boots without any issue. Explicitly specifying -march=core2 for newer GCC allows U-Boot proper to boot again. Examine assembly codes of env_callback_init and there is no SSE instruction in that function hence U-Boot continues to boot. core2 seems to be the oldest arch in GCC that supports 64-bit. Like 32-bit U-Boot build we use -march=i386 which is the most conservative cpu type so that the image can run on any x86 processor, let's do the same for the 64-bit U-Boot build.
