With RAM init debug messages enabled, debug messages take up a lot of
flash space in romstage, with many repeated verbiage. By breaking
them up and factoring out the common verbiage, made possible with
printk(BIOS_DEBUG, "%s", ...), compiler can help deduplicate things
and make the romstage smaller.
When building for asus/p2b-ls with CONFIG_DEBUG_RAM_SETUP, this patch
shrunk romstage by 152 bytes.

The rationale behind this change is that multiple nested bridges using a
lot of bus numbers and IO resources is not likely to be a common hotplug
setup. When there is a large amount of hotplug ports using 32
subordinate busses results in boot failures (e.g. make qemu). 8K IO
busses for hotplug devices is also excessive in most use cases when only
64K is available in total (again make qemu results in failure to
allocate resources but does boot to payload).

This patch drops the assert check around
`FSP_MULTIPHASE_SI_INIT_RETURN_BROKEN` config to ensure
`fsp_get_pch_reset_status()` can be used by all other FSP APIs to know
the status of the pending reset.
As per recent debug it has been found that, FSP is accumulating all
platform resets and executing a single reset from FSP Notify Phase.
As coreboot skipped calling into the FSP Notify APIs hence, it might
have missed the scope to issue the platform reset.
Going forward coreboot needs to implement the corresponding logic to be
able to identify any pending platform reset request and execute to
complete the silicon initialization flow.

Before the bootblock stage starts setting up the CAR mode, it sends
`POST_BOOTBLOCK_CAR` POST code. However, before the definition for
`POST_BOOTBLOCK_CAR` was introduced in the commit
0d34a50a36 , the value `0x20` was used.
At that point, `0x20` means "entry into CAR mode" and `0x21` means
"the cache memory region is cleared". Right now we are sending the
same POST code twice, which makes no sense.
So we can do the following (todo: drop me after we decided which one is
more appropriate):
1) Drop it (current patchset does exactly that)
2) Introduce POST code similar to POST_SOC_CLEARING_CAR and use it
before the cache memory region is cleared.

Traditionally, display init during vboot "verified/secure/normal

default behavior for vboot, meaning skip display init during verified
boot mode.
However, if the intention is to show the OEM splash screen (using
BMP_LOGO config) during boot, then the policy enforced by vboot needs
to be overridden. This can be done by setting the BMP_LOGO config flag.
If BMP_LOGO is not enabled, then the vboot policy will be followed and
display init will be skipped.
This change was made to allow OEMs to show their splash screen during
boot, even if the system is in verified/secure/normal mode.

Since it's not obvious, add comments to acpigen_resource_word,
acpigen_resource_dword and acpigen_resource_qword to clarify out what
the magic number in byte 0 means. The most significant bit of byte 0
indicates if it is a small or large resource data type. In the case of
the MSB being 0, it's a small resource data type (aka type 0), and the
other bits encode bit the type and size of the item; if the MSB is 1,
it's a large resource data type (aka type 1), and the other bits just
encode the type and there are two separate bytes to encode the size.
Beware that the large resource's data type values in the ACPI
specification don't include the MSB that's set, but only the 7 lower
bits.
