A USB disk behind a hub may take longer time to respond command.
Prior to the patch, a magic 2000 ms is set. This patch introduces
a python control (USB_CMD_TIMEOUT) for customizing the timeout if
need. The patch also extends the default timeout to 4196 ms.
This patch does not impact booting time when a platform boots with
a good-conditioning usb disk, because the timeout only takes effect
when a disk does not respond to a USB inquiry for a long time.

If there is DEBUG output during PCI enumeration, it could cause SBL
hang due to invalid PCI bar resource. In this case, SBL will force
to return 0 for any serial port register read. And it might cause
dead loop because of LSR_TXRDY bit polling in SerialPortWrite().
To avoid this potential dead loop, it is required to set LSR_TXRDY
bit for LSR_OFFSET register read if the PCI resource is invalid.

According to PCI spec, it is required to check the multi-function

Convert the line endings stored for all text files in the repository to
LF. The majority previously used DOS-style CRLF line endings. Add a
.gitattributes file to enforce this and treat certain extensions as
never being text files.
Update PatchCheck.py to insist on LF line endings rather than CRLF.
However, its other checks fail on this commit due to lots of
pre-existing complaints that it only notices because the line endings
have changed.
Silicon/QemuSocPkg/FspBin/Patches/0001-Build-QEMU-FSP-2.0-binaries.patch
needs to be treated as binary since it contains a mixture of line
endings.
This change has implications depending on the client platform you are
using the repository from:
* Windows
The usual configuration for Git on Windows means that text files will
be checked out to the work tree with DOS-style CRLF line endings. If
that's not the case then you can configure Git to do so for the entire
machine with:
git config --global core.autocrlf true
or for just the repository with:
git config core.autocrlf true
Line endings will be normalised to LF when they are committed to the
repository. If you commit a text file with only LF line endings then it
will be converted to CRLF line endings in your work tree.
* Linux, MacOS and other Unices
The usual configuration for Git on such platforms is to check files out
of the repository with LF line endings. This is probably the right thing
for you. In the unlikely even that you are using Git on Unix but editing
or compiling on Windows for some reason then you may need to tweak your
configuration to force the use of CRLF line endings as described above.
* General

SBL might change MTRR to enable framebuffer cache. Current code
only handles BSP MTRR programming, and it is necessary to sync
up the MTRR programming for all APs as well. This patch added
a function to sync up MTRRs for all APs.
Please note, this MTRR sync up is a simplified version for SBL
case since SBL will only add new MTRRs for GFX framebuffer.
To do a full generic MTRRs sync up, it is required to flush cache,
reload TLB, etc. And it will come with some performance impacts.

This patch adjusted the following debug message for USB libraries:

When multiple USB mass storage devices are connected to the
target, it is not clear to the end user which one is selected
for boot. This patch added code to print the USB mass storage
device manufacturer and product name string. In this way, it
is easier for the end user to identify specific USB device.
It can also be used to determine the HwPart field for USB boot
option. HwPart for USB boot option is mapped to the USB mass
storage device index detected on the platform. BTW, to allow
boot from multiple USB mass storage devices, the optoin
ENABLE_MULTI_USB_BOOT_DEV needs to be enabled. So this patch
enabled ENABLE_MULTI_USB_BOOT_DEV by default.

Current SBL will always append "acpi_rsdp=" as part of the command

Current XHCI library does a big loop to poll the status of a
USB command execution. In each loop it will delay 1us until
it completes or reachs the timeout. When the loop is very big,
the accumulated 1us delay together will be shifted far beyond
the original timeout requested. This is because of the inaccuracy
of the 1us delay provided by ACPI timer library. This patch
addressed this issue by checking the actual executed time rather
than looping with delay.
