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>
2017-11-21rockchip: back-to-bootrom: allow passing a cmd to the bootromPhilipp Tomsich
The BROM supports forcing it to enter download-mode, if an appropriate result/cmd-word is returned to it. There already is a series to support this in review, so this prepares the (newly C-version) of the back-to-bootrom code to accept a cmd to passed on to the BROM. All the existing call-sites are adjusted to match the changed function signature. Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Andy Yan <andy.yan@rock-chips.com>
2017-11-21rockchip: back-to-bootrom: replace assembly-implementation with C-codePhilipp Tomsich
The back-to-bootrom implementation for Rockchip has always relied on the stack-pointer being valid on entry, so there was little reason to have this as an assembly implementation. This provides a new C-only implementation of save_boot_params and back_to_bootrom (relying on setjmp/longjmp) and removes the older assembly-only implementation.

2017-10-01rockchip: bootrom: add definitions to retrieve BROM boot-sourcePhilipp Tomsich
The Rockchip BROM allows reading where it booted from from SRAM. This adds the necessary definitions (as received from Kever) for the location of this information in the RK3399's SRAM and naming for the constants used.

2017-04-18rockchip: Print a message when returning to the bootromSimon Glass
At present if the return to bootrom fails (e.g. because you are not using the Rockchip's bootrom's pointer table in MMC) then the board prints SPL message and hangs. Print a message first if we can, to help in understanding what happened when it hangs.

2017-03-16rockchip: Move bootrom-related declarations to a headerHeiko Stübner
So far spl-boards have declared the back_to_brom() function as simple extern in the files themself. That doesn't scale well if every boards defines this on its own. Therefore move the declarations to a bootrom header. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Tested-by: Kever Yang <kever.yang@rock-chips.com>
