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>
2017-08-11Kconfig: Drop CONFIG_CMD_PCI_ENUMSimon Glass
This option enables the 'pci enum' command. It is only enabled by a few board and these have not yet been converted to driver model, which always enables this command. It seems easiest to just remove this option. The affected boards can be converted to use driver model for PCI if needed.

2017-06-02pci: Correct cast for sandboxSimon Glass
This gives a warning with some native compilers: cmd/pci.c:152:11: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 3 has type ‘u64 {aka long unsigned int}’ [-Wformat=] Fix it with a cast. Signed-off-by: Simon Glass <sjg@chromium.org>

Add 'pci regions' which lists the I/O and memory regions accessible from the PCI controller. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-12-09cmd: pci: add option to parse and display BAR informationYehuda Yitschak
Currently the PCI command only allows to see the BAR register values but not the size and actual base address. This little extension parses the BAR registers and displays the base, size and type of each BAR. Signed-off-by: Yehuda Yitschak <yehuday@marvell.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2016-01-28Implement "pci enum" command for CONFIG_DM_PCIStephen Warren
With CONFIG_DM_PCI enabled, PCI buses are not enumerated at boot, as they are without that config option enabled. No command exists to enumerate the PCI buses. Hence, unless some board-specific code causes PCI enumeration, PCI-based Ethernet devices are not detected, and network access is not available. This patch implements "pci enum" in the CONFIG_DM_PCI case, thus giving a mechanism whereby PCI can be enumerated. do_pci()'s handling of case 'e' is moved into a single location before the dev variable is assigned, in order to skip calculation of dev. The enum sub-command doesn't need the dev value, and skipping its calculation avoids an irrelevant error being printed. Using a command to initialize PCI like this has a disadvantage relative to enumerating PCI at boot. In particular, Ethernet devices are not probed during PCI enumeration, but only when used. This defers setting variables such as ethact, ethaddr, etc. until the first network-related command is executed. Hopefully this will not cause further issues. Perhaps in the long term, we need a "net start/enum" command too?

2016-01-25Remove the cmd_ prefix from command filesSimon Glass
Now that they are in their own directory, we can remove this prefix. This makes it easier to find a file since the prefix does not get in the way.
