Update the FPDT boot performance record's ebs_entry and ebs_exit
fields in bootm_final() to record the time when we're about to
hand off to the operating system.
The timing is recorded just before we start the kernel, after all
device cleanup and before interrupts are disabled, which corresponds
to the ExitBootServices phase in UEFI.
If EFI is used to boot, a further update could be made, but that is
left for later.
Avoid including asm/acpi_table.h on platforms without ACPI. Ad a special
case for the QEMU RISC-V ACPI board.
Series-changes: 2
- Depend on ACPIGEN instead of GENERATE_ACPI_TABLE
