To deprecate VBOOT_VBNV_CMOS [1], replace VBOOT_VBNV_CMOS with
VBOOT_VBNV_FLASH for boards using SOC_INTEL_BRASWELL.
Currently BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is selected for
CPU_INTEL_HASWELL, SOC_INTEL_BRASWELL and others (see [2]). However,
there seems to be no particular reason on those platforms. We've dropped
the config for haswell. Now do the same for SOC_INTEL_BRASWELL, so that
VBOOT_VBNV_FLASH can be enabled.
VBOOT_VBNV_FLASH is enabled for the following boards:
- facebook/fbg1701: A 0x2000 RW_NVRAM region is allocated, with the
FW_MAIN_A(CBFS) size reduced by 0x2000.
- google/cyan, intel/strago: Repurpose RW_UNUSED as RW_NVRAM.

There is an ongoing effort to deprecate VBOOT_VBNV_CMOS [1] and replace
with VBOOT_VBNV_FLASH. However, the rambi's CAR is too small for early
flash access in romstage:
/usr/local/google/home/yupingso/projects/coreboot/util/crossgcc/xgcc/bin/i386-elf-ld.bfd:

More precisely, DCACHE_RAM_SIZE is 0x8000, and the current .car.data
size is 0x76c0. If BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is unselected,
then the _bss region will increase by 0x10c8 bytes (for global variables
such as `elog_mirror_buf` and `sfg`), so that .car.data will exceed
0x8000.
Since rambi has reached its AUE (2021-09-01), disable
MAINBOARD_HAS_CHROMEOS and VBOOT configs.

This patch adds a new section to the coding style which codifies
existing practices about how to handle errors and how to use the die()
and assert() macros. Also clean up some references to Linux-specific
facilities that do not exist in coreboot in the adjacent function return
type guidelines, and add a small blurb of documentation to the
definition of the assert() macro itself.

Contents of unsigned AMDFW in RW sections are verified twice in PSP
verstage - first time by vboot verifying the firmware body, second time
by CBFS verification while the file is loaded to update PSP about the
boot region. This redundant verification adds to boot time. Minimize the
redundancy by splitting the EFS header from the AMDFW body and keep them
as 2 separate CBFS files. This helps to improve the boot time by another
25 ms.

through passing an optional --body-location parameter to the amdfwtool.
If that option is not passed, then EFS will be written in the same file
