grub-memtest.iso was originally intended as a means of testing all
the different boot modes. But as we publish it on memtest.org, let's
have a more user-friendly version that provides menu entries for the
most commonly needed boot options. The original test ISO can still
be built by 'make GRUB_CFG=grub-test grub-iso'.
When two controllers are attached to a physical port (e.g. in the
case of EHCI and its companion controllers, problems can occur if
the BIOS still has control of one controller when we try to use the
other one. So perform a first pass to scan the PCI bus and take
ownership of and reset all the controllers we find, and perform a
second pass to initialise the controllers and probe for attached
devices.
As we don't support hot plugging, split the second pass into two,
with the first probing the EHCI controllers and handing over any
low and full speed devices to the companion controllers, and the
second probing the remaining controller types.
Introduce bcd_to_ui8 for converting BCD into uint8_t.
Currently, smbus.c is the only user of this code so I placed it there.
Once (if?) there are more, we may want to move it to a dedicated ".h" file.
Replace all BCD conversion in smbus.c with a call to bcd_to_ui8().
No change in the binary output.
Convert calling / return convention for all parse_spd_* functions from
returning the value of spd_info structure to updating the received
reference. This also allows to move / remove some boilerplate code,
like initializing spdi/curspd and setting slot_num.
At the end, print_smbus_startup_info wants curspd to be updated,
so we can do this in a more efficient way.

Replace SPD SKU reading code repeated multiple times across
all the parse_spd_* functions with a dedicated read_sku function.
Convert spd_infos.sku from len+data into classic NULL-terminated C-string.
Takes the same space, but simplifies handling. Also, use char instead of
uint8_t so no conversion is needed when printing.
Change the way how the end of part number is handled. Stop on the first
non-ASCII character and then trim all trailing spaces. This allows SKUs
with two (or more) spaces inside the name to be handled properly.
Finally, fix incorrect / inconsistent part number length handling, with
the following end result:
- parse_spd_sdram: 18 [73-90] (no change)
- parse_spd_rdram: 18 [73-90] (no change)
- parse_spd_ddr: 18 [73-90] (no change)
- parse_spd_ddr2: 18 [73-90] (no change)
- parse_spd_ddr3: 20+1=21 -> 18 [128-145]
- parse_spd_ddr4: 20+1=21 -> 20 [329-348]
- parse_spd_ddr5: 29+1=30 -> 30 [521-550] (technicaly no change)

* [DDR5] Fix rounding errors on SPD Timings
* [DDR5] Add a rounding factor of ~0.3% according to JEDEC to solve the last rounding issue found on NETAC Modules
* [DDR5] Add missing package ranks per channel parameter in total module capacity algorithm
* [DDR4] Fix rounding issues in SPD timings & frequency
* [DDR3] Fix rounding issues in SPD timings & frequency decoding. Check XMP Profile #2. Add a quirk for Kingston based on very early XMP 1.0 specs
* [DDR2] Fix CAS detection & rounding issues in SPD timings w/ EPP
* [DDR] Correct SPD timings rounding issues & add support for x.5 CAS latencies
* [SDR] Correct SPD Timings decoding due to rounding errors
* Add various JEP106 Manufacturers found while debugging
* Update timings display function to handle x.5 CAS
Some CPU like Intel Yorkfield (Core 2 Quad) reports max CPUID > 0xB but doesn't support CPUID = 0xB. Check x2apic flag to be sure CPUID 0xB is supported. If not, fallback to older detection method
Most legacy BIOSs will support USB legacy keyboard emulation. Using that
will avoid having to reserve memory for the USB drivers, and should
improve the chance of having a working keyboard without having to work
around various USB device quirks.
* Add new heap manager.
* Convert OHCI driver to use new heap manager.
* Convert UHCI driver to use new heap manager.
* Convert EHCI driver to use new heap manager.
* Convert XHCI driver to use new heap manager.
* Convert SMP to use new heap manager.
* Add a "usbinit" boot option to handle various buggy USB devices.
This replaces the "keyboard=buggy-usb" option, and adds a second
workaround to handle the problem seen in issue #107.
Add AP Enumeration to distinguish E-Core from P-Core on Intel Hybrid CPUs, and exclude them from the selected cores by default. Including E-Cores slows down some tests and takes longer to catch memory errors.
A new exclude_ecores flag has been added in config.c to include E-Cores if needed.
- Enable VGA/FB to output box drawing characters while maintaining VT100
character set for serial. Shorten and simplify the screen setup code.
- Track the background color to decide if the serial output needs to be
inverted. Remove no longer needed logic for known areas of the screen that
need to be inverted. As a bonus - popup menu can now be also inverted on
serial.
- Reduce the amount of data sent to serial by using CR+LF when possible
instead of always relying on absolute positioning. Add tty_print()
for positioning the cursor, remove no longer needed tty_print().
- Remove no longer needed "LF -> LF+CR" logic from serial_echo_print().
