* smbios: Allow writing to the coreboot version stringSimon Glass2021-03-271-0/+20
| | | | | | | | | | | | | | When U-Boot is booted from coreboot the SMBIOS tables are written by coreboot, not U-Boot. The existing method of updating the BIOS version string does not work in that case, since gd->smbios_version is only set when U-Boot writes the tables. Add a new function which allows the version to be updated by parsing the tables and writing the string in the correct place. Since coreboot provides a pointer to the SMBIOS tables in its sysinfo structure, this makes it easy to do the update. Signed-off-by: Simon Glass <sjg@chromium.org>
* smbios: Add more options for the BIOS version stringSimon Glass2021-02-061-0/+12
| | | | | | | | | | | | | | | | | | At present the version string is obtained from PLAIN_VERSION. Some boards may want to configure this using the device tree, since the build system can more easily insert things there after U-Boot itself is built. Add this option to the code. Also in some cases the version needs to be generated programmatically, such as when it is stored elsewhere in the ROM and must be read first. To handle this, keep a pointer around so that it can be updated later. This works by storing the last string in the context, since it is easier than passing out a little-used extra parameter. Provide a function to update the version string. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* smbios: Use char consistently for the eos memberSimon Glass2021-02-061-2/+2
| | | | | | | | | At present a few of the structs use u8 instead of char. This is a string, so char is better. Update them. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Christian Gmeiner <christian.gmeiner@gmail.com> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+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>
* x86: Use unsigned long for address in table generationSimon Glass2017-02-061-2/+2
| | | | | | | | We should use unsigned long rather than u32 for addresses. Update this so that the table-generation code builds correctly on 64-bit machines. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
* smbios: Expose in efi_loader as tableAlexander Graf2016-10-191-0/+1
| | | | | | | | | | | | We can pass SMBIOS easily as EFI configuration table to an EFI payload. This patch adds enablement for that case. While at it, we also enable SMBIOS generation for ARM systems, since they support EFI_LOADER.

* smbios: Allow compilation on 64bit systemsAlexander Graf2016-10-191-2/+2
| | | | | | | | | | | | | | The SMBIOS generation code passes pointers as u32. That causes the compiler to warn on casts to pointers. This patch moves all address pointers to uintptr_t instead. Technically u32 would be enough for the current SMBIOS2 style tables, but we may want to extend the code to SMBIOS3 in the future which is 64bit address capable.
