2017-05-17sunxi: Store the device tree name in the SPL headerSiarhei Siamashka
This patch updates the mksunxiboot tool to optionally add the default device tree name string to the SPL header. This information can be used by the firmware upgrade tools to protect users from harming themselves by trying to upgrade to an incompatible bootloader. The primary use case here is a non-removable bootable media (such as NAND, eMMC or SPI flash), which already may have a properly working, but a little bit outdated bootloader installed. For example, the user may download or build a new U-Boot image for "Cubieboard", and then attemept to install it on a "Cubieboard2" hardware by mistake as a replacement for the already existing bootloader. If this happens, the flash programming tool can identify this problem and warn the user. The size of the SPL header is also increased from 64 bytes to 96 bytes to provide enough space for the device tree name string.

2017-05-17ARM: uniphier: add weird workaround code for LD20Masahiro Yamada
When booting from ARM Trusted Firmware, U-Boot runs in EL1-NS. The boot flow is as follows: BL1 -> BL2 -> BL31 -> BL33 (i.e. U-Boot) This boot sequence works fine for LD11 SoC (Cortex-A53), but LD20 SoC (Cortex-A72) hangs in U-Boot. The solution I found is to read sctlr_el1 and write back the value as-is. This should be no effect, but surprisingly fixes the problem for LD20 to boot. I do not know why.

Remove 'pad-offset' of soc_gpio_s5_0, soc_gpio_s5_1, soc_gpio_s5_2, pin_usb_host_en0 and pin_usb_host_en1. These offsets are actually wrong. Correct value should be added by 0x2000, but since they are supposed to be 'mode-gpio', 'pad-offset' is not needed at all.

Add a device-tree property use-lvl-write-cache that will cause writes to lvl to be cached instead of read from lvl before each write. This is required on some platforms that have the register implemented as dual read/write (such as Baytrail). Prior to this fix the blue USB port on the Minnowboard Max was unusable since USB_HOST_EN0 was set high then immediately set low when USB_HOST_EN1 was written.

2017-05-17x86: acpi: Fix Windows S3 resume failureBin Meng
U-Boot sets up the real mode interrupt handler stubs starting from address 0x1000. In most cases, the first 640K (0x00000 - 0x9ffff) system memory is reported as system RAM in E820 table to the OS. (see install_e820_map() implementation for each platform). So OS can use these memories whatever it wants. If U-Boot is in an S3 resume path, care must be taken not to corrupt these memorie otherwise OS data gets lost. Testing shows that, on Microsoft Windows 10 on Intel Baytrail its wake up vector happens to be installed at the same address 0x1000. While on Linux its wake up vector does not overlap this memory range, but after resume kernel checks low memory range per config option CONFIG_X86_RESERVE_LOW which is 64K by default to see whether a memory corruption occurs during the suspend/resume (it's harmless, but warnings are shown in the kernel dmesg logs). We cannot simply mark the these memory as reserved in E820 table because such configuration makes GRUB complain: unable to allocate real mode page. Hence we choose to back up these memories to the place where we reserved on our stack for our S3 resume work. Before jumping to OS wake up vector, we need restore the original content there.
