2019-06-21pci: Avoid assigning PCI resources that are below 0x1000Bin Meng1-2/+3
commit b7598a43f2b4 ("[PATCH] Avoid assigning PCI resources from zero address") only moved the bus lower address to 0x1000 if the given bus start address is zero. The comment said 0x1000 is a reasonable starting value, hence we'd better apply the same adjustment when the given bus start address is below 0x1000.

2018-05-26PCI: autoconfig: Don't allocate 64-bit addresses to 32-bit only resourcesTuomas Tynkkynen1-1/+6
Currently, if we happen to allocate an address requiring 64 bits to a device only supporting 32-bit BARs, the address eventually gets silently truncated to 32 bits. Avoid this by adding a new flag to pciauto_region_allocate() to bail out in such situations. Signed-off-by: Tuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+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>

2015-12-01dm: pci: Move common auto-config functions to a common fileSimon Glass1-0/+128
Some functions will be used by driver model and legacy PCI code. To avoid duplication, put these in a separate, shared file. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
