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>
2016-01-24dm: pci: Convert bios_emu to use the driver model PCI APISimon Glass
At present this BIOS emulator uses a bus/device/function number. Change it to use a device if CONFIG_DM_PCI is enabled. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

2014-11-25bios_emulator: Add vesa support and allow ROMs to be passed in as dataSimon Glass
As well as locating the ROM on the PCI bus, allow the ROM to be supplied to the emulator. Split the init up a little so that callers can supply their own interrupt routines. Also allow a vesa mode to be provided, to be selected once the BIOS run is complete. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-25pci: Add general support for execution of video ROMsSimon Glass
Some platforms don't have native code for dealing with their video hardware. In some cases they use a binary blob to set it up and perform required actions like setting the video mode. This approach is a hangover from the old PC days where a ROM was provided and executed during startup. Even now, these ROMs are supplied as a way to set up video. It avoids the code for every video chip needing to be provided in the boot loader. But it makes the video much less flexible - e.g. it is not possible to do anything else while the video init is happening (including waiting hundreds of milliseconds for display panels to start up). In any case, to deal with this sad state of affairs, provide an API for execution of x86 video ROMs, either natively or through emulation. Signed-off-by: Simon Glass <sjg@chromium.org>

We should have a public header so that users can avoid defining functions themselves. Signed-off-by: Simon Glass <sjg@chromium.org>
