We generate a few tables on x86 today that really can be used on ARM just
the same. One such example is the SMBIOS table, which people use with tools
like "dmidecode" to identify which hardware they are running on.
We're slowly growing needs to collect serial numbers from various devices
on ARM and SMBIOS seems the natural choice. So this patch set moves the
current SMBIOS generation into generic code and adds serial number exposure
to it.
I have verified that I get a correct serial number printed in dmidecode on
the RPi3.
v1 -> v2:
- Also populate UUID
- Fix whitespace
v2 -> v3:
- Move efi smbios generation to own file
- New patch: Make type4 table available on all archs
Alexander Graf (8):
x86: Move table csum into separate header
x86: Move smbios generation into arch independent directory
efi_loader: Expose efi_install_configuration_table
smbios: Allow compilation on 64bit systems
smbios: Generate type 4 on non-x86 systems
smbios: Expose in efi_loader as table
efi_loader: Fix efi_install_configuration_table
smbios: Provide serial number
