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>
2016-01-14arm: mvebu: Add runtime detection of UART (xmodem) boot-modeStefan Roese
This patch adds runtime detection of the Marvell UART boot-mode (xmodem protocol). If this boot-mode is detected, SPL will return to the BootROM to continue the UART booting. With this patch its now possible, to generate a U-Boot image that can be booted either from the strapped boot-device (e.g. SPI NOR, MMC, etc) or via the xmodem protocol from the UART. In the UART case, the kwboot tool will dynamically insert the UART boot-device type into the image. And also patch the load address in the header, so that the mkimage header will be skipped (as its not expected by the Marvell BootROM). This simplifies the development for Armada XP / 38x based boards. As no special images need to be generated by selecting the MVEBU_BOOTROM_UARTBOOT Kconfig option. Since the Kconfig option MVEBU_BOOTROM_UARTBOOT is not needed any more, its now completely removed.

2015-10-21arm: mvebu: Add option to use UART xmodem protocol via kwbootStefan Roese
This patch enables the use of the kwboot tool, to boot mainline U-Boot on the Marvell Armada XP/38x SoC's. This is done by returning to the SoC's BootROM after SPL has initialized the SDRAM. We need to make sure to not reconfigure the internal register space and MBARs. Otherwise the BootROM will not be able to continue after SPL jumps back to it. To use this feature, please don't forget to change the BOOT_FROM line in your board specfic kwbimage.cfg file this way: BOOT_FROM uart Tested on these Marvell eval boards: DB-MV784MP-GP - Armada XP DB-88F6820-GP - Armada 38x Signed-off-by: Stefan Roese <sr@denx.de> Cc: Dirk Eibach <eibach@gdsys.de> Cc: Kevin Smith <kevin.smith@elecsyscorp.com> Cc: Luka Perkov <luka.perkov@sartura.hr>
2015-05-05arm: armada-xp: Move SoC sources to mach-mvebuStefan Roese
Move arch/arm/cpu/armv7armada-xp/* -> arch/arm/mach-mvebu/* Since this platform will be extended to support other Marvell SoC's as well, lets rename it directly to mvebu. This will be used by the upcoming Armada 38x suport (A38x).
