2016-07-21image: fix IH_ARCH_... values for uImage compatibilityMasahiro Yamada
Commit 555f45d8f916 ("image: Convert the IH_... values to enums") accidentally changed some IH_ARCH_... values. Prior to that commit, there existed a gap between IH_ARCH_M68K and IH_ARCH_MICROBLAZE, like follows. #define IH_ARCH_SPARC64 11 /* Sparc 64 Bit */ #define IH_ARCH_M68K 12 /* M68K */ #define IH_ARCH_MICROBLAZE 14 /* MicroBlaze */ #define IH_ARCH_NIOS2 15 /* Nios-II */ The enum conversion broke the compatibility with existing uImage files. Reverting 555f45d8f916 will cause build error unfortunately, so here is a more easy fix. I dug the git history and figured out the gap was introduced by commit 1117cbf2adac ("nios: remove nios-32 arch"). So, I revived IH_ARCH_NIOS just for filling the gap. I added comments to each enum block. Once we assign a value to IH_... it is not allowed to change it.

2016-07-20mtd: cfi_flash: fix polling for bit XSR.7 on Intel chipsDaniel Schwierzeck
flash_full_status_check() checks bit XSR.7 on Intel chips. This should be done by only checking bit 7 and not by comparing the whole status byte or word with 0x80. This fixes the non-working block erase in the pflash emulation of Qemu when used with the MIPS Malta board. MIPS Malta uses x32 mode to access the pflash device. In x32 mode Qemu mirrors the lower 16 bits of the status word into the upper 16 bits. Thus the CFI driver gets a status word of 0x8080 in x32 mode. If flash_full_status_check() uses flash_isequal(), then it polls for XSR.7 by comparing 0x8080 with 0x80 which never becomes true.

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.

2016-07-15ARM: 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: PSCI: Add missing CONFIG_ARMV7_PSCI_NR_CPUS for PSCI enabled platformsChen-Yu Tsai

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>
