* Recognise VT52/VT100/VT220 key escape sequences on serial console.
Map function keys to '0' to '9' and cursor keys to 'u', 'd', 'l',
'r', as is done for legacy and USB keyboards. Ignore all other
special key sequences.
* Make serial_echo_print() and tty_goto() static.
These are local to serial.c. Making them static saves a few bytes.
* Update keyboard.h to document cursor key mapping.
* Added some escape codes for terminals & VT100+
Change input order to check TTY first
* Replace comments about PF6-10

* Add USB hub quirk to support AMI virtual keyboard (issue #523)
From testing it appears that the AMI virtual devices do not work
correctly if you disable one port on the virtual hub then reuse the
USB address for a device connected to another port on that hub. So
add a quirk to detect the virtual hub from its vendor/product ID
and leave all ports on that hub active when performing the scan for
USB keyboards. This will permanently reserve a bit more memory, but
not significantly so.
* Replace hard-coded USB vendor ID with macro definition.
* Update Intel i801 PCI device IDs list from the Linux driver.
* Add support for MTL-P (eg: NUC 14th Gen)

The usbdebug option may now be optionally followed by "=hub" or "=kbd",
which enables details of the configuration and endpoint descriptors to
be printed when scanning for hubs or keyboards respectively. This can
easily result in more than one screenful of information (and we can't
say "press any key to continue" before we've completed the scan and set
up the keyboard handler), so a 1 second delay is added after printing
each line of detailed information.
* loongarch: adjust 2K/3B6000M DDR rate factor
* loongarch: Supports fewer cache layers than L3
For example: 2K2000 chip does not have L3, but has L2.
If L2Cache is not flushed to memory, it will cause read and write data errors after cache_off.
If a legacy BIOS has enabled PS/2 mouse input, the bytes received on
port 0x60 may come from either the keyboard or the mouse. Currently
we treat all bytes as keyboard input, which means mouse input will be
translated into arbitrary key codes. This may cause a memory test to
be interrupted or aborted. We should instead disable or ignore any
mouse input.
Although it should be possible to reconfigure the PS/2 controller to
disable mouse input, it's quite likely that there's some quirky H/W
out there that makes this more complicated than it seems. The simple
solution is to detect mouse input by checking whether bit 5 of the
received byte is set and discarding it if so.
Currentilly, it only compares the root bus DID is 0x7A00 which sometimes
fails, a new logic was added to compare the 7A2000 EHCI DID to fix it.

* Split SPD parsing and printing code from smbus.c to spd.c
Move all SPD parsing and printing code from smbus.{c,h} to spd.{c,h}.
Introduce parse_spd() function, moving the parse_spd_* selection logic
from print_smbus_startup_info(), allowing to keep parse_spd_* static.
Remove static from get_spd() and update print_smbus_startup_info()
to use parse_spd() which also simplifies the code flow.
Move LINE_SPD into display.h and rename it to ROW_SPD. Update print_spdi()
to use explicit row number where the SPD info needs to be printed.
Rename ram_info into ram_info_t, rename print_smbus_startup_info()
into print_spd_startup_info.
Do not initialize ram.freq to 0, this is the initial value already.
Do not set curspd.isValid to False, the first thing that parse_spd()
does is setting the entire struct to 0, that also sets isValid to False.
print_spd_startup_info() from smbus.c is technically a skeleton now
so each arch can have its own version, adjusted as needed. Once
LA64 changes land, we can think how we can even make it arch agnostic.
* Add -fexcess-precision=standard to CFLAGS for build(32,64)/Makefile
Recent switch from -std=c11 to -std=gnu11 done in 53ca89f ("Add

parsing code (and potentially in other places) due to change of
floating point precision. Restore the original behavior by

The existing algorithm both read and wrote data beyond the end of the
array and, when moving data, moved it in the wrong direction. Replace
it with a bog-standard insertion sort algorithm. The resulting code
is smaller and probably faster, as memmove() is not in-lined.
* Add a file containing useful macro definitions, currently a single top-level macro for obtaining the size of an array; use it to replace a sizeof(x) / sizeof(x[0]) construct in system/smbus.c . This requires switching the GCC build mode from C11 to C11 with GCC extensions.
* Initial NUMA awareness (#12) support: parse the ACPI SRAT to build up new internal structures related to proximity domains and affinity; use these structures in setup_vm_map() and calculate_chunk() to skip the work on the processors which don't belong to the proximity domain currently being tested.
Tested on a number of 1S single-domain, 2S multi-domain and 4S multi-domain platforms.
SKIP_RANGE(iterations) trick by Martin Whitaker.
* Add boot option to rotate screen display through 90 degrees.
Some machines have a detachable display that can be used in either
portrait or landscape orientations, and require software to rotate
the displayed image accordingly. There is no way to detect the
current orientation through the BIOS, so provide a boot option to
control this. Hopefully we only need to support one (+90 degree)
angle.
Note that the rotate option only works in graphical mode. When booted
by a legacy BIOS using text mode, we have to rely on the BIOS to do
what's necessary.
* Extend boot command line options for display screen control.
Replace "rotate" option with "screen.rhs-up" and "screen.lhs-up" to
allow rotation in either direction. Add a "screen.mode=<w>x<h>"
option to set a preferred width <w> and height <h> for the UEFI
frame buffer. Also allow "screen.mode=bios" to use the default
UEFI frame buffer resolution.
* Add more debug output for EFI frame buffer mode.
* Replicate command line parsing of screen options in efisetup.c.
Trying to do it only once in screen.c didn't work, because static
variables initialied to zero are placed in the bss section, and we
don't zero the bss section until after efisetup() is executed.
The resulting code is in fact smaller, because the compiler can
optimise better when everything is local.
* Add a boot command line option for efisetup debug.
* Improve EFI debug test screen pattern.
* Document the new screen and efidebug boot command line options.
* Fix typo in README.
* Initial commit for ECC support. Preliminary support for AMD Zen.
* Clear ECC registers at startup
* Add config flag (enable_ecc_polling) to toggle ECC polling. (Currently disabled by default for v7 release)
* Optimize the JEP106 list by using __attribute__((packed)) to remove padding. The x86 & x86_64 series support unaligned accesses just fine, after all, and this is not remotely a hot path.
* Optimize several string-related constructs by switching to fixed-length char arrays, which avoids pointers + relocations.
* app/interrupt.c: array of different-length strings, but most of those are lengthy enough for this to be a clear win, especially on x86_64;
* system/usbhcd.c: array of same-length strings;
* tests/tests.h: array of structs containing same-length strings.
* Reduce the size of the list of tests by using a narrower type for the cpu mode, which reduces padding.
* cpuinfo: Add support for Vortex86
Hardcode cache for family 5, use CPUID cache info for family 6.
* cpuinfo: Add support for Vortex86EX
The EX does not have brand string so hardcode name and cache.
* In determine_cache_size(), add an additional test to ensure that only
Vortex86 CPUs are handled, allowing Zhaoxin CPUs to fall through.
Also, remove the no_temperature var to keep only the enable_temperature flag
Older Atom still have the enable_temperature flag hard-coded to false until further tests are done

Change terminology from Intel-based 'MCH' (Memory Controller Hub) to more universal 'IMC' (Integrated Memory Controller) Integrate imc_type var into imc struct. Remove previously created AMD SNM header file
* Various Cleanup 2
* Change DDR5 display format for IMC specs
DDR5 Freq can be > 10000 and timings up to 63-127-127-127, which overwflow the available space.
This commit remove the raw frequency on DDR5 (which may be incorrect due to Gear mechanism) and leave a bit of space to display the Gear engaged in the future
On some modern ULV cores (eg: Gracemont), the 2 following I/O reads to check APIC Timer working status are fused in the frontend, leading to the same value being reported twice and the code falling back to the (unusually disabled on these platforms) PIT timer.
Whether this behavior is intentional or not is unknown.
As usleep/sleep is not available at this point, a dirty delay is added between the two reads.
* cpuinfo: Fix WinChip and Cyrix/NSC CPU name and cache info
Always populate the cache info from extended CPUID, it is not used for
Intel CPUs, even though it is present, and is useful for non-Intel CPUs.
Fix the CPU name and cache sizes for Centaur and Cyrix/NSC CPUs without
brand string, which are the WinChip C6 and all Cyrix CPUs except the
Media GXm.
For the Media GXm and Geode GXm/GXLV/GX1, which are available with both
Cyrix and NSC vendor strings, hardcode the L1 cache size. The Geode GX2
uses standard cache info.
* Add 'Intel' in CPU names for older CPUs
* Add 'Transmeta' and 'IDT' in CPU names for older CPUs
