| | | | | | | | | | | | | | | | | | | | | | This commit relocates the exception vectors. As ARM1176 and ARMv7 have the security extensions, it uses VBAR.

* | arm: make .vectors section allocatableGeorges Savoundararadj2014-10-29-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A regression was introduced in commit 41623c91. The consequence of that is the non-relocation of the section .vectors symbols : _undefined_instruction, _software_interrupt, _prefetch_abort, _data_abort, _not_used, _irq and _fiq. Before commit 41623c91, the exception vectors were in a .text section. The .text section has the attributes allocatable and executable [1]. In commit 41623c91, a specific section is created, called .vectors, with the attribute executable only. What have changed between commit 41623c91^ and 41623c91 is the attribute of the section which contains the exception vectors. An allocatable section is "a section [that] occupies memory during process execution" [1] which is the case of the section .vectors. Adding the lacking attribute (SHF_ALLOC or "a") for the definition of the section .vectors fixed the issue. To summarize, the fix has to mark .vectors as allocatable because the exception vectors reside in "memory during execution" and they need to be relocated.

* Revert "ARM: SPL: do not set gd again"Tom Rini2014-09-16-0/+3
| | | | | | | | | | | | | | At the high level, the problem is that we set gd multiple times (and still do, even after the commit we're reverting). We set important parts of gd to the copy which is not above stack but rather in the data section. For the release, we're going to revert this change and for the next release we shall correct things to only, really, set gd once to an appropriate location and ensure that comments about it are correct too.

* arm: Fix _start for CONFIG_SYS_DV_NOR_BOOT_CFGBenoît Thébaudeau2014-09-11-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | The boards using CONFIG_SYS_DV_NOR_BOOT_CFG (i.e. calimain, da850evm_direct_nor and enbw_cmc) had the _start symbol defined after the CONFIG_SYS_DV_NOR_BOOT_CFG word rather than before it in arch/arm/lib/vectors.S. Because of that, if by lack of luck 'gd->mon_len = (ulong)&__bss_end - (ulong)_start' (see setup_mon_len()) was a multiple of 4 kiB (see reserve_uboot()), then the last BSS word overlapped the first word of the following reserved RAM area (or went beyond the top of RAM without such an area) after relocation because __image_copy_start did not match _start (see relocate_code()). This was broken by commit 41623c9 'arm: move exception handling out of start.S files', which defined _start twice (before and after the CONFIG_SYS_DV_NOR_BOOT_CFG word), then by commit 0a26e1d 'arm: fix a double-definition error of _start symbol', which kept the definition of the _start symbol after the CONFIG_SYS_DV_NOR_BOOT_CFG word. This new commit fixes this issue by restoring the original behavior, i.e. by defining the _start symbol before the CONFIG_SYS_DV_NOR_BOOT_CFG word.

* arm: Make reset position-independentBenoît Thébaudeau2014-09-11-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Some boards, like mx31pdk and tx25, require the beginning of the SPL code to be position-independent. For these two boards, this is because they use the i.MX external NAND boot, which starts by executing the first NAND Flash page from the NFC page buffer. The SPL then needs to copy itself to its actual link address in order to free the NFC page buffer and use it to load the non-SPL image from Flash before running it. This means that the SPL runtime address differs from its link address between the reset and the initial copy performed by board_init_f(), so this part of the SPL binary must be position-independent. This requirement was broken by commit 41623c9 'arm: move exception handling out of start.S files', which used an absolute address to branch to the reset routine. This new commit restores the original behavior, which just performed a relative branch. This fixes the boot of mx31pdk and tx25.

| | | | | | | | | | | | | | | | | | | | On an Odroid U3 board, the SOC is unable to reset the eMMC card in the DWMMC mode by the cpu software reset. Manual reset of the card by switching proper gpio pin - fixes this issue. Such solution needs to add a call to pre reset function. This is done by the reset_misc() function, which is called before reset_cpu(). The function reset_misc() is a weak function.

* ARM: Fix overflow in MMU setupMarek Vasut2014-08-30-1/+1
| | | | | | | | | | | | | | | | | | The patch fixes a corner case where adding size to DRAM start resulted in a value (1 << 32), which in turn overflew the u32 computation, which resulted in 0 and it therefore prevented correct setup of the MMU tables. The addition of DRAM bank start and it's size can end up right at the end of the address space in the special case of a machine with enough memory. To prevent this overflow, shift the start and size separately and add them only after they were shifted. Hopefully, we only have systems in tree which have DRAM size aligned to 1MiB boundary. If not, this patch would break such systems. On the other hand, such system would be broken by design anyway. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Albert ARIBAUD <albert.u.boot@aribaud.net>

* ARM: HYP/non-sec: allow relocation to secure RAMMarc Zyngier2014-07-28-13/+9
| | | | | | | | | | | | | | | | | | | | The current non-sec switching code suffers from one major issue: it cannot run in secure RAM, as a large part of u-boot still needs to be run while we're switched to non-secure. This patch reworks the whole HYP/non-secure strategy by: - making sure the secure code is the *last* thing u-boot executes before entering the payload - performing an exception return from secure mode directly into the payload - allowing the code to be dynamically relocated to secure RAM before switching to non-secure.

* arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo2014-07-03-0/+234
| | | | | | | | | | | | | | | | | | | | | | The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF images and u-boot, and does this for virtual platforms by using semihosting. This commit extends this idea by allowing u-boot to also use semihosting to load the kernel/ramdisk/dtb. This eliminates the need for a bootwrapper and produces a more realistic boot sequence with virtual models. Though the semihosting code is quite generic, support for armv7 in fastmodel is less useful due to the wide range of available silicon and the lack of a free armv7 fastmodel, so this change contains an untested armv7 placeholder for the service trap opcode. Please refer to doc/README.semihosting for a more detailed description of semihosting and how it is used with the armv8 virtual platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot has supported two kinds of asm-offsets.h. One is generic for all architectures and its source is located at ./lib/asm-offsets.c. The other is SoC specific and its source is under SoC directory. The problem here is that only boards with SoC directory can use the asm-offsets infrastructure. Putting asm-offsets.c right under CPU directory does not work. Now a new demand is coming. PowerPC folks want to use asm-offsets. But no PowerPC boards have SoC directory. It seems inconsistent that some boards add asm-offsets.c to SoC directoreis and some to CPU directories. It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib. This commit merges asm-offsets.c under SoC directories into arch/$(ARCH)/lib/asm-offsets.c. By the way, I doubt the necessity of some entries in asm-offsets.c. I am leaving refactoring to the board maintainers. Please check "TODO" in the comment blocks in arch/{arm,nds32}/lib/asm-offsets.c.

We are not happy about parsing config.mk again and again. We have to keep the same behavior with a different way. By adding "CONFIG_" prefix, this macro appears in include/autoconf.mk, include/spl-autoconf.mk. (And treating USE_PRIVATE_LIBGCC as CONFIG macro is reasonable enough.) Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes" in arch/arm/cpu/arm720t/tegra*/config.mk, whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk. It means Tegra enables PRIVATE_LIBGCC only for SPL. We can describe the same behavior by adding #ifdef CONFIG_SPL_BUILD # define CONFIG_USE_PRIVATE_LIBGCC #endif to include/configs/tegra-common.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we tell the compiler to optimize for ARMv7 (and ARMv6 for that matter) it assumes a default of SCTRL.A being cleared and unaligned accesses being allowed and fast at the hardware level. We set this bit and must pass along -mno-unaligned-access so that the compiler will still breakdown accesses and not trigger a data abort. To better help understand the requirements of the project with respect to unaligned memory access, the Documentation/unaligned-memory-access.txt file has been added as doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1 tag of the kernel.
