it did before. It is a thin wrapper around get_keystroke_full() now

Specifically added support for 16 and 32bpp files, in addition to
24bpp. The function bmp_show() in bmp.c has had the hardcoded check
for 24bpp replaced with a general bpp check that uses a % to check for
remainder, and returns 1 if the remainder is >0. The previous method
for adjusting the BMP data (raw_data_format_adjust_24bpp) relied on a
preset 3*bytes_per_line_src, this has been changed and the
multiplication is now performed in the function's arguments. This
change still allows someone else to reuse the same function for
1/2/4bpp support if necessary. The file util.h has been modified to
reflect this decision.
The changes to raw_data_format_adjust() is based on an abandoned patch
by Gert Menke (submitted March 14, 2017), credit to them for that
change and the addition of *bpp to bmp_get_info().

On QEMU it's necessary to manually reset the BIOS memory region
between 0xc0000-0x100000 on a reboot. After this manual memory reset
is completed, it's not valid to use the generic reset mechanisms.
Rename qemu_prep_reset() to qemu_reboot() and change the function to
immediately reboot after the code memcpy.
This fixes a bug that could cause code corruption on reboots - calling
the udelay() function (as invoked by i8042_reboot and/or pci_reboot)
was not valid after the BIOS was memcpy'd.

Currently the MTRRs and MSR_IA32_FEATURE_CONTROL are not restored on S3
resume. Because these have to be applied to all processors, SMP setup
has to be added to S3 resume.
There are two differences between the boot and resume paths. First,
romfile_* is not usable in the resume paths so we separate out the
remaining common code to a new smp_scan function. Second, smp_msr has
to be walked on the BSP as well, so we extract that out of handle_smp
and into a new function smp_write_msrs. Then, resume can call
smp_write_msrs on the BSP followed by smp_scan to initialize the APs.

This patch adds an new menu entry to the main menu. This menu item enables
the user to enter a TPM control menu which allows control of those aspects
of the TPM's state that can only be controlled while in the firmware
and while physical presence can be asserted.
If the machine has a TPM, the boot menu will look as follows, with
the new menu item accessible by pressing the 't' key.
Select boot device:
1. ata0-1: QEMU HARDDISK ATA-7 Hard-Disk (6144 MiBytes)
2. Legacy option rom
3. iPXE (PCI 00:03.0)
t. TPM Menu
Upon pressing t the TPM submenu will be shown:
The Trusted Platform Module (TPM) is a hardware device in this machine.
It can help verify the integrity of system software.
The current state of the TPM is:
Enabled and active
Ownership has not been taken
A user can take ownership of the TPM
Available options are:
d. Disable the TPM
v. Deactivate the TPM
p. Prevent installation of an owner
If no change is desired or if this menu was reached by mistake, press ESC to
reboot the machine.
The TPM menu only shows those options that are currently accessible considering
the state of the TPM.
The patch adds several functions for sending those messages to the TPM
required for supporting those menu items.

Some Chromebooks (with Baytrail CPUs) apparently do not support

I've been successfully using SeaBIOS as secondary bootloader. In more details
I have GRUB2-as-payload in flash together with coreboot. SeaBIOS binary is on
the HDD and loaded by GRUB when needed. This has an unfortunate consequence
that I have to keep vga oprom in flash even if usually I boot without it. This
patches makes bios.bin.elf multiboot executable with files passed as modules.
Example:
menuentry "SeaBIOS (mb)" --unrestricted {
root=ahci0,2
multiboot /bios.bin.elf
module /vgabios_x230.rom name=pci8086,0166.rom
}
the parameter name= specifies under which name SeaBIOS will see it.

This patch implements the TCG BIOS interrupt handler 1ah. It is for
example used by trusted grub.
This patch adds an implementation of SHA1 (following NIST specs., IETF RFC 3147
and Wikipedia) for speeding up measurements of code. Trusted Grub for example
makes use of this interface and measures (calculates SHA1) of the Linux kernel
and initrd. Those files can be rather large and hunting their bytes through
the TIS interface as part of the int handler commands invoked by trusted grub
does take quite some time due to the many vmexits the interface is creating
(one per byte).
There is also a threshold for the size of data to hash (100k) below which
the TPM is used and above the internal faster SHA1 algorithm is used.
This patch for example enables trusted grub to interact with the TPM
and take additional measurements.

Modify the int 1587 handler to check if the POST phase is still
running. If it is, use bigreal mode segment limits so that the caller
remains in bigreal mode when the 1587 handler completes. This helps
with SeaVGABIOS' use of "direct" framebuffer accesses (an option rom
may attempt to display text during its option rom execution which can
cause SeaVGABIOS to make the int 1587 calls).

On resume, the OS queries the power management event that
caused it. In order to complete this task, it executes some
reads to the piix pm io space. This all happens before the
OS has a chance to restore the PCI config space for devices,
so it is bios's responsibility to make sure the pm IO space
is configured correctly. (During suspend, the piix pm
configuration space is lost).
Note: For 'ordinary' pci devices the config space is
saved by the OS on sleep and restored on resume.
