Daisuke Nojiri 6732b4fcdc vboot: Add config to enable EC EFS support
This patch makes coreboot set VBSD_EC_EFS flag if CONFIG_VBOOT_EC_EFS
is set. Depthcharge/Vboot uses this flag to determine whether it can
update EC when it's already running a RW copy.

BUG=b:65028930
BRANCH=none
TEST=Verify soft sync runs successfully on Fizz.

Furquan Shaikh c18aa1c777 vboot: Use "Google_" as VBOOT_FWID_MODEL prefix if CHROMEOS is set
CONFIG_MAINBOARD_VENDOR is customizable by OEM for Chrome OS
devices. However, VBOOT_FWID_MODEL indicates the firmware vendor and
hence if CHROMEOS is selected, then VBOOT_FWID_MODEL should always
prefix "Google_" instead of CONFIG_MAINBOARD_VENDOR.

Julius Werner 46f292f9bf vboot: Separate board name and version number in FWID with a dot
It's standard practice in vboot that the FWID consists of
<board_name>.<version_number> (e.g. Google_Kevin.8785.57.0). In fact,
some tools rely on this and cut the string at the first dot to
separate the two.

The current Kconfig default in coreboot instead leads to ugly,
parser-breaking FWIDs like Google_Kevin4.5-1234-5678abcd. This patch
fixes that.

Julius Werner 58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

Julius Werner 73d042bd90 vboot: Disallow separate verstage after romstage, try to clarify logic
No board has ever tried to combine CONFIG_SEPARATE_VERSTAGE with
CONFIG_VBOOT_STARTS_IN_ROMSTAGE. There are probably many reasons why
this wouldn't work (e.g. x86 CAR migration logic currently always
assumes verstage code to run pre-migration). It would also not really
make sense: the reason we use separate verstages is to decrease
bootblock size (mitigating the boot speed cost of slow boot ROM SPI
drivers) and to allow the SRAM-saving RETURN_FROM_VERSTAGE trick,
neither of which would apply to the after-romstage case. It is better to
just forbid that case explicitly and give programmers more guarantees
about what the verstage is (e.g. now the assumption that it runs pre-RAM
is always valid).

Since Kconfig dependencies aren't always guaranteed in the face of
'select' statements, also add some explicit compile-time assertions to
the vboot code. We can simplify some of the loader logic which now no
longer needs to provide for the forbidden case. In addition, also try to
make some of the loader logic more readable by writing it in a more
functional style that allows us to put more assertions about which cases
should be unreachable in there, which will hopefully make it more robust
and fail-fast with future changes (e.g. addition of new stages).

Julius Werner fa8fa7dd54 vboot: Remove VBOOT_DYNAMIC_WORK_BUFFER Kconfig option
VBOOT_DYNAMIC_WORK_BUFFER and VBOOT_STARTS_IN_ROMSTAGE are equivalent in
practice. We can't have a dynamic work buffer unless we start in/after
romstage, and there'd be no reason to go with a static buffer if we do.
Let's get rid of one extra option and merge the two.

Julius Werner 94d9411415 vboot: Remove CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL Kconfig option
CHIPSET_PROVIDES_VERSTAGE_MAIN_SYMBOL allows the SoC directory to
provide its own main() symbol that can execute code before the generic
verstage code runs. We have now established in other places (e.g. T210
ramstage) a sort of convention that SoCs which need to run code in any
stage before main() should just override stage_entry() instead. This
patch aligns the verstage with that model and gets rid of the extra
Kconfig option. This also removes the need for aliasing between main()
and verstage(). Like other stages the main verstage code is now just in
main() and can be called from stage_entry().

There's no need to be SPI specific w.r.t. how the flash is
connected. Therefore, use the RW boot device to write the
contents of VBNV. The erasable check was dropped because that
information isn't available. All regions should be aligned
accordingly on the platform for the underlying hardware
implementation. And once the VBNV region fills the erase
will fail.

Julius Werner 4157bd8d61 vboot: Move TPM-related Kconfig selects from CHROMEOS to VBOOT
CONFIG_VBOOT was recently moved to be independent from CONFIG_CHROMEOS.
However, the latter still has some 'select' clauses to ensure that
required TPM libraries are built. The TPM is an essential part of vboot,
and without these libraries the vboot code cannot compile... therefore,
they should be moved under CONFIG_VBOOT.
