2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-02-07spl: eMMC/SD: Provide one __weak spl_boot_mode() functionLukasz Majewski
The goal of this patch is to clean up the code related to choosing SPL MMC boot mode. The spl_boot_mode() now is called only in spl_mmc_load_image() function, which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled. To achieve the goal, all per mach/arch implementations eligible for unification has been replaced with one __weak implementation.

2017-10-04treewide: replace with error() with pr_err()Masahiro Yamada
U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err(). Done with the help of Coccinelle, excluing tools/ directory.

2016-12-06ARM: socfpga: Add boot0 hook to prevent SPL corruptionMarek Vasut
Valid Altera SoCFPGA preloader image must contain special data at offsets 0x40, 0x44, 0x48 and valid instructions at address 0x4c or 0x50. These addresses are by default used by U-Boot's vector table and a piece of reset handler, thus a valid preloader corrupts those addresses slightly. While this works most of the time, this can and does prevent the board from rebooting sometimes and triggering this issue may even depend on compiler. The problem is that when SoCFPGA performs warm reset, it checks the addresses 0x40..0x4b in SRAM for a valid preloader signature and header checksum. If those are found, it jumps to address 0x4c or 0x50 (this is unclear). These addresses are populated by the first few instructions of arch/arm/cpu/armv7/start.S: ffff0040 <data_abort>: ffff0040: ebfffffe bl ffff0040 <data_abort> ffff0044 <reset>: ffff0044: ea000012 b ffff0094 <save_boot_params> ffff0048 <save_boot_params_ret>: ffff0048: e10f0000 mrs r0, CPSR ffff004c: e200101f and r1, r0, #31 ffff0050: e331001a teq r1, #26 Without this patch, the CPU will enter the code at 0xffff004c or 0xffff0050 , at which point the value of r0 and r1 registers is undefined. Moreover, jumping directly to the preloader entry point at address 0xffff0000 will also fail, because address 0xffff004. is invalid and contains the preloader magic. Add BOOT0 hook which reserves the area at offset 0x40..0x5f and populates offset 0x50 with jump to the entry point. This way, the preloader signature is stored in reserved space and can not corrupt the SPL code.
