2021-10-26efi_loader: add SMBIOS table measurementMasahisa Kojima
TCG PC Client Platform Firmware Profile Specification requires to measure the SMBIOS table that contains static configuration information (e.g. Platform Manufacturer Enterprise Number assigned by IANA, platform model number, Vendor and Device IDs for each SMBIOS table). The device- and environment-dependent information such as serial number is cleared to zero or space character for the measurement. Existing smbios_string() function returns pointer to the string with const qualifier, but exisintg use case is updating version string and const qualifier must be removed. This commit removes const qualifier from smbios_string() return value and reuses to clear the strings for the measurement. This commit also fixes the following compiler warning: lib/smbios-parser.c:59:39: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] const struct smbios_header *header = (struct smbios_header *)entry->struct_table_address; Signed-off-by: Masahisa Kojima <masahisa.kojima@linaro.org>

SMBIOS tables only support 32bit addresses. If we don't have memory here handle the error gracefully: * on x86_64 fail to start U-Boot * during UEFI booting ignore the missing table Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-03-27smbios: Allow writing to the coreboot version stringSimon Glass
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>
2021-02-06smbios: Add more options for the BIOS version stringSimon Glass
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>

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>

2016-10-19smbios: Allow compilation on 64bit systemsAlexander Graf
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.
