Clock config setup must be run from cache. Original code used "goto"
to prefetch the code required to update the VCO (by jumping after
the code and back before). The GCC since at least 12.1.0 and clang
since at least 13.0.1 will elimitate these jumps.
Use inline assembler to force the original code flow.
TEST=Verified assembly code is the same as generated by GCC 12.1.0
and boot tested on Kontron 986LCD-M.

There is an ongoing effort to deprecate VBOOT_VBNV_CMOS, and replace it
with VBOOT_VBNV_FLASH [1]. Since SOC_INTEL_BROADWELL doesn't support
flash writes in early stages (BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES),
drop vboot as well as ChromeOS support for all broadwell boards,
including auron, jecht and wtm2.

Commit 75226bb879 ("Makefile.inc: Generate master header and pointer
as C structs") may cause objcopy to copy a wrong section of object file
resulting in miscompiled image with missing CBFS master header. This
makes the usage of secondary payloads impossible.
For example a wrong section for CONFIG_ANY_TOOLCHAIN +
objcopy 2.38-slack151 will copy ".note.gnu.property".
This patch constraints the sections to .data and .bss only.

This adds a style file for the markdown linter mdl.
The tool can be found on archive.org at the URL:
https://web.archive.org/web/20220407032312/https://github.com/markdownlint/markdownlint
This does 2 things:
- Sets that line length limit to 72 characters as requested in the docs
about writing the documentation.
- Excludes several rules that were added for a particular markdown
parser. My opinion is that these rules make the text versions of the
markdown harder to read.
To use this style file, run:
$ mdl -s Documentation/.mdl_style.rb

Mediatek SoC uses part of the L2 cache as SRAM before DRAM is ready.
After DRAM is ready, we should invoke disable_l2c_sram to reconfigure
the L2C SRAM as L2 cache.

and Intel has updated their GPIO naming schemes too (see the GPIO
implementation worksheet #641238) so use double digit GPIO pad numbers.

e.g.
GPP_A0 -> GPP_A00,
GPP_V2 -> GPP_V02,
GPP_C9 -> GPP_C09 etc.
