* doc: qemu-arm: Drop highmem=off referencesTuomas Tynkkynen2018-05-261-4/+3
| | | | | | | | Now that U-Boot works fine with highmem enabled, there is no need to tell users to disable highmem. Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Reviewed-by: Simon Glass <sjg@chromium.org>
* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-3/+1
| | | | | | | | | | | | | | | | | | | | 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>
* ARM: Document AArch64 version of qemu-armTuomas Tynkkynen2018-01-191-5/+16
| | | | | | | | | | | | It's mostly obvious, except that QEMU is annoying and requires an explicit '-cpu cortex-a57' (or some other 64-bit core) to actually run in 64-bit mode. While at it, remove the references to setting the ARCH environment variable; that is not used in U-Boot.
