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>

2015-06-04x86: qemu: Adjust VGA initializationBin Meng
As VGA option rom needs to run at C segment, although QEMU PAM emulation seems to only guard E/F segments, for correctness, move VGA initialization after PAM decode C/D/E/F segments. Also since we already tested QEMU targets to differentiate I440FX and Q35 platforms, change to locate the VGA device via hardcoded b.d.f instead of dynamic search for its vendor id & device id pair.

2015-06-04x86: qemu: Enable legacy IDE I/O ports decodeBin Meng
QEMU always decode legacy IDE I/O ports on PIIX chipset. However Linux ata_piix driver does sanity check to see whether legacy ports decode is turned on. To make Linux ata_piix driver happy, turn on the decode via IDE_TIMING register. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>
