Skylake is a mess, especially with coreboot. We have now a present and
configured software sequencing interface with SCGO supposedly being
readonly (Apollo Lake has that feature and a strap documented, Skylake
behaviour might be the same). As we can't easily check if it's read-
only, just enable hardware sequencing by default (even if the software
sequencing interface seems usable).

Using serprog on FreeBSD to read an SPI flash (MX25L6406) via an
Arduino Nano V3 with flashrom hangs after 5 seconds while reading. The
problem is that kernel method "ttydisc_rint" ignores some bytes. It
happens due to enabled IEXTEN local flag of termios. TTY cuts a few
bytes, Arduino reads 11264 bytes, but flashrom gets only 11244 bytes
and waits for the remaining 20 bytes.
The fix is simple: turn off the IEXTEN local flag.
Tested on Arduino Nano V3 + FreeBSD 12-CURRENT.

The (old) ST (now Micron) M25P05 does only support RES for identification.
Unfortunately, the vendor datasheet states the same ID as for the M25P10
(0x10) and thus flashrom has treated these two as evil twins in the past.
However, real hardware confirmed that the real ID of this chip is 0x05.

This allows us to support flash chips in any of the following
configurations, regardless of whether the chip powers up in 3-byte or
4-byte address mode.
- standard commands with extended address register (*_4ba_ereg) or
direct commands (*_4ba_direct) in 3-byte address mode (.set_4ba =
spi_exit_4ba_*)
- standard commands (*_4ba) or direct commands (*_4ba_direct) in
4-byte address mode (.set_4ba = spi_enter_4ba_*)
- direct commands (*_4ba_direct) in either address mode (.set_4ba =

Large flash chips usually support special instructions to work with
4-bytes address directly from 3-bytes addressing mode and without
do switching to 4-bytes mode. There are 13h (4BA Read), 12h (4BA Program)
and 21h,5Ch,DCh (4BA Erase), correspondingly. However not all these
instructions are supported by all large flash chips. Some chips
support 13h only, some 13h,12h,21h and DCh, but not 5Ch. This depends
on the manufacturer of the chip.
This patch provides code to use direct 4-bytes addressing instructions.
This code should work but it tested partially only. My W25Q256FV has
support for 4BA_Read (13h), but doesn't have support 4BA_Program (12h)
and 4BA_Erase instructions. So, direct 4BA program and erase
should be tested after.

On some flash chips data with addresses more than 24-bit field
can address may be accessed by using Extended Address Register.
The register has 1-byte size and stores high byte of 32-bit address.
Then flash can be read from 3-bytes addressing mode with writing
high byte of address to this Register. By using this way we have
access to full memory of a chip. Some chips may support this method
only.
This patch provides code use Extended Address Register.

This patch integrates code of the previous patch into Flashrom's code.
All the integrations is around 3 functions spi_nbyte_read, spi_nbyte_program
and spi_byte_program. After this patch then are not static and can be called
by their pointers saved in flashchips array. Also I added to flashrom.c some
code to switch a chip to 4-bytes addressing mode. And one error message is
corrected in spi.c because it's not suitable for 32-bit addresses.

If flash chip is switched to 4-bytes addressing mode then all
read/erase/program instructions will be switched from 3-bytes mode
to 4-bytes mode. Then well known instructions like 03h (Read),
02h (Program) and 20h,52h,D8h (Erase) will become one byte longer
and accept 4-bytes address instead of 3-bytes.
This patch provides support for well known instructions in 4-bytes
addressing mode. Also here is the code to enter 4-bytes addressing
mode by execute the instruction B7h (Enter 4-bytes mode).

refine the pre-push hook:
- get rid of the concept of precious brances - all of them on the

using gerrit instead of a native git repository for staging purposes)
- likewise, only allow new versioned stable branches and no feature
branches there
