After the first firmware boot, the firmware is capable of
saving/restoring its context to/from IMR (Isolated Memory Region, set
aside by BIOS on startup). This capability improves the resume speed.

Due to an unexplained issue on Up2 boards, this capability is disabled
on ApolloLake.

For backwards compatibility, the regular boot flow is used with older
firmware. For added peace of mind, a kernel module parameter is
provided to force the regular boot flow - this shouldn't be necessary
since we've been testing these patches for 6+ months.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
