Tom Rini [Mon, 15 May 2017 16:17:49 +0000 (12:17 -0400)]
lib: move hash CONFIG options to Kconfig

Commit 94e3c8c4fd7b ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it.  Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool.  In many cases we can select
these because they are required to implement other drivers.  We also
correct how we include the various hashing algorithms in SPL.

This commit was generated as follows (after Kconfig additions):

[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

Retrieved the DCD table from:
board/freescale/mx6sabresd/mx6dlsabresd.cfg
(NXP U-Boot branch imx_v2015.04_4.1.15_1.0.0_ga)

Flashed SPL and u-boot.img to an SD card and could successfully boot it
on mx6q, mx6qp and mx6dl sabresd boards.

mx6sabresd: Prepare for supporting MX6DL

Currently only MX6Q/QP sabresd boards are supported in SPL.

In order to also support MX6DL we need to convert to using

dm: core: Add DM_FLAG_OS_PREPARE flag

This new flag can be added to DM device drivers, which need to do some
final configuration before U-Boot exits and the OS (e.g. Linux) is
started. The remove functions of those drivers will get called at
this stage to do these last-stage configuration steps.

x86: acpi: Fix Windows S3 resume failure

U-Boot sets up the real mode interrupt handler stubs starting from
address 0x1000. In most cases, the first 640K (0x00000 - 0x9ffff)
system memory is reported as system RAM in E820 table to the OS.
(see install_e820_map() implementation for each platform). So OS
can use these memories whatever it wants.

If U-Boot is in an S3 resume path, care must be taken not to corrupt
these memorie otherwise OS data gets lost. Testing shows that, on
Microsoft Windows 10 on Intel Baytrail its wake up vector happens to
be installed at the same address 0x1000. While on Linux its wake up
vector does not overlap this memory range, but after resume kernel
checks low memory range per config option CONFIG_X86_RESERVE_LOW
which is 64K by default to see whether a memory corruption occurs
during the suspend/resume (it's harmless, but warnings are shown
in the kernel dmesg logs).

We cannot simply mark the these memory as reserved in E820 table
because such configuration makes GRUB complain: unable to allocate
real mode page. Hence we choose to back up these memories to the
place where we reserved on our stack for our S3 resume work.
Before jumping to OS wake up vector, we need restore the original
content there.
