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>
2015-03-24remove unnecessary version.h includesRob Herring
Various files are needlessly rebuilt every time due to the version and build time changing. As version.h is not actually needed, remove the include.

2014-05-15arm: move exception handling out of start.S filesAlbert ARIBAUD
Exception handling is basically identical for all ARM targets. Factorize it out of the various start.S files and into a single vectors.S file, and adjust linker scripts accordingly. Signed-off-by: Albert ARIBAUD <albert.u.boot@aribaud.net>
2014-02-26arm: remove unneeded symbol offsets and _TEXT_BASEAlbert ARIBAUD

2013-10-17ARM: mxs: Setup stack in JTAG modeMarek Vasut
In case the MX23/MX28 is switched into JTAG mode via the BootMode select switches, the BootROM bypasses the CPU core registers initialization. This in turn means that the Stack Pointer (SP) register is not set as it is in every other mode of operation, but instead is only zeroed out. To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out. Note that in case the SP is already configured, we must preserve that exact SP value and must not modify it. This is important since in every other mode but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to continue it's operation after returned from SPL and the system would crash. Finally, add the JTAG mode switch identifier, so it's not recognised as Unknown mode.

2013-09-10ARM: mxs: Receive r0 and r1 passed from BootROMMarek Vasut
Make sure value in register r0 and r1 is preserved and passed to the board_init_ll() and mxs_common_spl_init() where it can be processed further. The value in r0 can be configured during the BootStream generation to arbitary value, r1 contains pointer to return value from CALL'd function. This patch also clears the value in r0 before returning to BootROM to make sure the BootROM is not confused by this value. Finally, this patch cleans up some comments in the start.S file.

2013-03-15Replace __bss_end__ with __bss_endSimon Glass
Note this is a tree-wide change affecting multiple architectures. At present we use __bss_start, but mostly __bss_end__. This seems inconsistent and in a number of places __bss_end is used instead. Change to use __bss_end for the BSS end symbol throughout U-Boot. This makes it possible to use the asm-generic/sections.h file on all archs. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-09-01MX28: Drop the cp15 reconfiguration from SPLMarek Vasut
The SPL doesn't need the CP15 reconfiguration, as that's what the BootROM does for us already. Moreover, when the CP15 is reconfigured and the code returns control to BootROM, the USB boot works no more. Remove the code and allow [1] to work properly as well.
