2016-07-19ARMv8: add the secure monitor firmware frameworkHou Zhiqiang
This framework is introduced for ARMv8 secure monitor mode firmware. The main functions of the framework are, on EL3, verify the firmware, load it to the secure memory and jump into it, and while it returned to U-Boot, do some necessary setups at the 'target exception level' that is determined by the respective secure firmware. So far, the framework support only FIT format image, and need to define the name of which config node should be used in 'configurations' and the name of property for the raw secure firmware image in that config. The FIT image should be stored in Byte accessing memory, such as NOR Flash, or else it should be copied to main memory to use this framework.

2016-07-19armv8: fsl-layerscape: add i/d-cache enable function to enable_cachesHou Zhiqiang
This function assume that the d-cache and MMU has been enabled earlier, so it just created MMU table in main memory. But the assumption is not always correct, for example, the early setup is done in EL3, while enable_caches() is called when the PE has turned into another EL.

2016-07-15ARM: PSCI: Make psci_get_cpu_stack_top local to armv7/psci.SChen-Yu Tsai
Now that we have a secure data section for storing variables, there should be no need for platform code to get the stack address.

2016-07-15ARM: Add CONFIG_ARMV7_SECURE_MAX_SIZE and check size of secure sectionChen-Yu Tsai
As the PSCI implementation grows, we might exceed the size of the secure memory that holds the firmware. Add a configurable CONFIG_ARMV7_SECURE_MAX_SIZE so platforms can define how much secure memory is available. The linker then checks the size of the whole secure section against this.

2016-07-15ARM: PSCI: Remove unused psci_text_end symbolChen-Yu Tsai

2016-07-15ARM: Add an empty secure stack sectionChen-Yu Tsai
Until now we've been using memory beyond psci_text_end as stack space for the secure monitor or PSCI implementation, even if space was not allocated for it. This was partially fixed in ("ARM: allocate extra space for PSCI stack in secure section during link phase"). However, calculating stack space from psci_text_end in one place, while allocating the space in another is error prone. This patch adds a separate empty secure stack section, with space for CONFIG_ARMV7_PSCI_NR_CPUS stacks, each 1 KB. There's also __secure_stack_start and __secure_stack_end symbols. The linker script handles calculating the correct VMAs for the stack section. For platforms that relocate/copy the secure monitor before using it, the space is not allocated in the executable, saving space. For platforms that do not define CONFIG_ARMV7_PSCI_NR_CPUS, a whole page of stack space for 4 CPUs is allocated, matching the previous behavior.

2016-07-15ARM: Page align secure section only when it is executed in situChen-Yu Tsai
Targets that define CONFIG_ARMV7_SECURE_BASE will copy the secure section to another address before execution. Since the secure section in the u-boot image is only storage, there's no reason to page align it and increase the binary image size. Page align the secure section only when CONFIG_ARMV7_SECURE_BASE is not defined. And instead of just aligning the __secure_start symbol, align the whole .__secure_start section. This also makes the section empty, so we need to add KEEP() to the input entry to prevent the section from being garbage collected. Also use ld constant "COMMONPAGESIZE" instead of hardcoded page size. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2016-07-15sunxi: Move remaining PSCI assembly code to CChen-Yu Tsai
This patch finishes the rewrite of sunxi specific PSCI parts into C code. The assembly-only stack setup code has been factored out into a common function for ARMv7. The GIC setup code can be renamed as psci_arch_init. And we can use an empty stub function for psci_text_end.

2016-07-15ARM: PSCI: Split out common stack setup code from psci_arch_initChen-Yu Tsai
Every platform has the same stack setup code in assembly as part of psci_arch_init. Move this out into a common separate function, psci_stack_setup, for all platforms. This will allow us to move the remaining parts of psci_arch_init into C code, or drop it entirely. Also provide a stub no-op psci_arch_init for platforms that don't need their own specific setup code. Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: Hans de Goede <hdegoede@redhat.com>

2016-07-15sunxi: FEL - Add the ability to recognize and auto-import uEnv-style dataBernhard Nortmann
The patch converts one of the "reserved" fields in the sunxi SPL header to a fel_uEnv_length entry. When booting over USB ("FEL mode"), this enables the sunxi-fel utility to pass the string length of uEnv.txt compatible data; at the same time requesting that this data be imported into the U-Boot environment. If parse_spl_header() in the sunxi board.c encounters a non-zero value in this header field, it will therefore call himport_r() to merge the string (lines) passed via FEL into the default settings. Environment vars can be changed this way even before U-Boot will attempt to autoboot - specifically, this also allows overriding "bootcmd". With fel_script_addr set and a zero fel_uEnv_length, U-Boot is safe to assume that data in .scr format (a mkimage-type script) was passed at fel_script_addr, and will handle it using the existing mechanism ("bootcmd_fel").

2016-07-15sunxi: Support booting from SPI flashSiarhei Siamashka
Allwinner devices support SPI flash as one of the possible bootable media type. The SPI flash chip needs to be connected to SPI0 pins (port C) to make this work. More information is available at: https://linux-sunxi.org/Bootable_SPI_flash This patch adds the initial support for booting from SPI flash. The existing SPI frameworks are not used in order to reduce the SPL code size. Right now the SPL size grows by ~370 bytes when CONFIG_SPL_SPI_SUNXI option is enabled. While there are no popular Allwinner devices with SPI flash at the moment, testing can be done using a SPI flash module (it can be bought for ~2$ on ebay) and jumper wires with the boards, which expose relevant pins on the expansion header. The SPI flash chips themselves are very cheap (some prices are even listed as low as 4 cents) and should not cost much if somebody decides to design a development board with an SPI flash chip soldered on the PCB. Another nice feature of the SPI flash is that it can be safely accessed in a device-independent way (since we know that the boot ROM is already probing these pins during the boot time). And if, for example, Olimex boards opted to use SPI flash instead of EEPROM, then they would have been able to have U-Boot installed in the SPI flash now and boot the rest of the system from the SATA hard drive. Hopefully we may see new interesting Allwinner based development boards in the future, now that the software support for the SPI flash is in a better shape :-) Testing can be done by enabling the CONFIG_SPL_SPI_SUNXI option in a board defconfig, then building U-Boot and finally flashing the resulting u-boot-sunxi-with-spl.bin binary over USB OTG with a help of the sunxi-fel tool: sunxi-fel spiflash-write 0 u-boot-sunxi-with-spl.bin The device needs to be switched into FEL (USB recovery) mode first. The most suitable boards for testing are Orange Pi PC and Pine64. Because these boards are cheap, have no built-in NAND/eMMC and expose SPI0 pins on the Raspberry Pi compatible expansion header. The A13-OLinuXino-Micro board also can be used.
