In commit 30f36c35e7 ("soc/amd: rework DRAM and fixed resource
reporting") the reporting of the DRAM resources was moved from the
northbridge PCI device to the domain device. amd_pci_domain_fill_ssdt
didn't skip those DRAM resources when generation the resource producer
ranges which made Windows 10 very unhappy when it tried to evaluating
the ACPI tables causing it to reboot in a loop. To fix this, add a check
to also skip the resources that have the IORESOURCE_STORED flag set when
generating the resource producer ranges for the PCI root.
TEST=Windows 10 now successfully boots and reboots again on Mandolin

It seems that reducing the return type of timer_hz() to uint32_t in
CB:78888 was a bad idea... some Intel platforms actually use their raw
CPU clock for the timestamp counter which can be higher than 4GHz. This
patch reverts it back to uint64_t.
Also remove the redundant assertion in timer/generic.c since timer_us()
itself already does that check.

It seems that we have some applications where we need to calculate a GCD
in 64 bits. Now, we could instantiate the algorithm multiple times for
different bit width combinations to be able to use the most efficient
one for each problem... but considering that the function usually only
gets called once per callsite per stage, and that software emulation of
64-bit division on 32-bit systems doesn't take *that* long either, we
would probably usually be paying more time loading the second instance
of the function than we save with faster divisions. So let's just make
things easy and always do it in 64-bit and then nobody has to spend time
thinking on which version to call.

In case printk does not work the current exception handler will print a
simple "!" to notify the developer that coreboot is actually there but
something went wrong.
The "!" can be quite confusing when it actually happens that printk does
not work. Since "!" doesn't really say much (if you don't know the
exception arm64 code) the developer (like me) can easily assume that
something went wrong while configuring clocks or baud rate of UART,
since the output seemingly does not seem to make sense.
This adds a little bit more output to assure the developer that what was
printed was actually intended to be printed. Therefore it prints
"EXCEPT" which assures the developer that this was intended output.
It also adds a comment above so that developer can more easily grep
for this message.
It has intentionally not been written as:
```
const char *msg = "\r\n!EXCPT!";
while (*msg)
__uart_tx_byte(*msg++);
```
because in this case the compiler will generate code that will place
`msg` somewhere in bootblock and the code will try to access this using
a memory address. In rare cases (if you link bootblock at the wrong
address) this memory address can be wrong and coreboot will not print
the message. Using individual calls to `__uart_tx_byte` ensures that the
compiler will generate code which directly puts the character bytes into
the argument register without referencing a variable in bootblock.

Drop the unneeded data_fabric_set_mmio_np function and the corresponding
SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION Kconfig symbol. In systems
with only one FCH, its MMIO region will be subtractively decoded and
there's no need to add a non-posted data fabric MMIO region after the
FSP/openSIL has already configured the data fabric decode windows. In
systems with more than one FCH, openSIL will already take care of
initializing everything for the additional FCH, so we also won't need to
do anything in that case. Since dropping this function also removes both
data_fabric_print_mmio_conf calls before and after adding the unneeded
non-posted MMIO region, replace the data_fabric_set_mmio_np call with a

Back in the days of the APIC bus, the IOAPIC IDs mustn't overlap with
the LAPIC IDs (0 to CONFIG_MAX_CPUS - 1), but since the IOAPIC and LAPIC
nowadays talk to each other via the system bus, an IOAPIC ID of 0 is
valid. When set_ioapic_id gets called with an IOAPIC ID of 0, it skipped
writing the IOAPIC ID to the corresponding IOAPIC register, so the code
was relying of the register having the expected default value of the
IOAPIC IO 0 for things to work as expected. The case of the IOAPIC ID
being 0 is the most common case in coreboot, since that's what
register_new_ioapic_gsi0 will end up doing. Fix this issue by not making
the io_apic_write call conditional on ioapic_id being non-zero. The only
southbridge that doesn't call register_new_ioapic_gsi0, calls
set_ioapic_id with the IOAPIC ID 2 for which this won't cause any
changes in behavior.

The MTCL function provides a country list to the Linux kernel via an
ACPI function in SSDT for MediaTek WiFi chipsets that are capable of
operating on the 6GHz band. The country list is used to selectively
disable 6GHz and 5.9GHz operation based on the country the device is
operating in.
The function needs to read a binary file and send it as a package via
the MTCL method in SSDT for PCIe WiFi with MediaTek chipsets.
Change Summary:
* Add src/drivers/wifi/generic/mtcl.c to abstract functionaltity related

* Add write_mtcl_aml function to convert the byte data into the format
expected by the MTCL functionality in the Linux kernel.
* Add validate_mtcl function to validate that the byte data read in
from a file is in the expected format.
* Add write_mtcl_function function to read a binary file called
"wifi_mtcl".bin" from cbfs, then call validate_mtcl to verify that
it is in an expected format, and if so write the aml via acpigen
* Add config flag DRIVERS_MTK_WIFI to src/drivers/wifi/generic in order
to include MediaTek WiFi specific functionality
* Add config flag USE_MTCL which depends on DRIVERS_MTK_WIFI and
enables including the specific ACPI function defined in SSDT
* Add config flag CONFIG_MTCL_CBFS_FILEPATH which depends on
DRIVERS_MTK_WIFI which enables configuring the file to add as
"wifi_mtcl.bin"
* Add a call to write_mtcl_function to src/drivers/wifi/generic/acpi.c
to include the MTCL function in SSDT for MTK WiFi devices when
USE_MTCL is enabled.
* Add MediaTek VID to src/include/device/pci_ids.h.

and pretty hard to read (and does some unnecessary questionable things
like the type-punning stuff which leads to suboptimal code generation),
so this reimplements it from scratch (that also helps with the
licensing).
This algorithm is prepared to take in a pre-calculated "wide" checksum
in a machine-register-sized data type which is then narrowed down to 16
bits (see RFC 1071 for why that's valid). This isn't used yet (and the
code will get optimized out), but will be used later in this patch
