2022-02-04armv8: remove no longer needed lowlevel_init.SAndre Przywara
When we added Allwinner SoC support to ARMv8, we needed to pull in an implementation of lowlevel_init() calling the C function s_init(), as sunxi required it as this time. The last few patches got rid of this bogus requirement, and as sunxi was still the only user, we can now remove this lowlevel_init.S from ARMv8 altogether.

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>
2017-01-04armv8: add lowlevel_init.SAndre Przywara
For boards that call s_init() when the SPL runs, we are expected to setup an early stack before calling this C function. Implement the proper AArch64 version of this based on the ARMv7 code. This allows sunxi boards to setup the basic peripherals even with a 64-bit SPL.
