4677f6bbfa lib/bootmem: tightly couple bootmem_init to bootmem_write_memory_table
In https://review.coreboot.org/25383 people were confused about the
ordering of bootmem calls w.r.t. when entries are exposed to the OS. To
alleviate this add a notion of bootmem being initialized. In addition to
that, only mark bootmem initialized when bootmem_write_memory_table() is
called. Any other calls to bootmem before that will report an error on
the console.

96ed92d49d boardid: Add helpers to read sku_id strapping into coreboot tables
On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.

4ec3d9d69e boardid: Switch from Kconfig to weak functions
This patch switches the board_id and ram_code helper framework to use
weak functions rather than Kconfigs to determine whether the board
supplies these IDs. This cuts down on the amount of boilerplate Kconfigs
many boards have to set and also gives them more flexibility, such as
being able to determine at runtime whether a given ID is present.

e2f17f782f boardid: Minor clean up and standardization
Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

ec477346bf Kconfig: Remove BOARD_ID_MANUAL option
The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the
Urara board which is now long dead, and have never been used anywhere
else. They were trying to do something that we usually handle with a
separate SKU ID these days, whereas BOARD_ID is supposed to be reserved
for different revisions of the same board/SKU. Get rid of it to make
further refactoring of other options easier.

Also shove some stuff back into the Urara mainboard that should've never
crept into generic headers.

Zero the framebuffer structure so if it is not filled in (either if
no display is present or if there is an error) then it does not
provide garbage data to the payload.

This was noticed when booting a board without a display attached as
the payload wrote to the framebuffer at a random address.

With this change the payload can properly handle the case where a
display is not attached and not corrupt memory.

08f93599a9 cr50: process uninitialized values gracefully
The vboot code tries reading rollback protection indices from the TPM,
and if the attempt to read returns TPM_E_BADINDEX, it decides that the
TPM has not yet been initialized for the Chromebook use, and needs to
be taken through the factory initialization sequence.

TPM_E_BADINDEX is an internal representation of the TPM error 0x28b,
generated on attempts to read a non existing NVMEM space.

If the space exists, but has never been written the TPM returns error
0x14a. This condition (the space exists but not written) could happen
if the previous factory initialization attempt was interrupted right
after the space was created.

Let's map this error to the same internal representation
(TPM_E_BADINDEX) so that the Chrome OS device could recover when this
condition occurs.

BRANCH=reef, gru
BUG=b:37443842
TEST=verified that the Pyro device stuck in TPM error state recovered
      when this patch was applied.
