Gabe Black 93d9f92cfb spi: Change spi_xfer to work in units of bytes instead of bits.
Whenever spi_xfer is called and whenver it's implemented, the natural unit for
the amount of data being transfered is bytes. The API expected things to be
expressed in bits, however, which led to a lot of multiplying and dividing by
eight, and checkes to make sure things were multiples of eight. All of that
can now be removed.

BUG=None
TEST=Built and booted on link, falco, peach_pit and nyan and looked for SPI
errors in the firmware log. Built for rambi.

In particular if a device uses a lower power state like U2 it may

Dave Frodin c50c0ab456 drivers/spi: Reduce the per loop delay of spi_flash_cmd_poll_bit()
At the end of some SPI operations the SPI device needs to be polled
to determine if it is done with the operation. For SPI data writes
the predicted time of that operation could be less than 10us.
The current per loop delay of 500us is adding too much delay.
This change replaces the delay(x) in the do-while loop with a
timer so that the actual timeout value won't be lengthened by the
delay of reading the SPI device.

Paul Menzel 0089c2418b intel/lynxpoint: Make inclusion of Intel ME optional
Current build configuration always wants to include an Intel Management Engine
(ME) firmware (`me.bin`) on Intel Lynx Point systems.  However, we can have a
working coreboot without it, as long as the factory delivered ME firmware is
kept untouched in the flash ROM. So let the user decide if a ME firmware will
be included in the build by introducing the Kconfig option `HAVE_ME_BIN`.

The same was done in commit 99fd30e4 (sandybridge: Make inclusion of me.bin
optional) [1] for Intel Sandy Bridge (BD82x6x).

Paul Menzel 5218e61651 intel/lynxpoint: Allow building without IFD (descripter.bin)
On newer Intel systems, like Intel Lynx Point, the flash ROM is shared
between the host processor (BIOS), its Management Engine (ME) and an
integrated Ethernet controller (GbE). The layout of the flash ROM (and
other information) is kept in the so called Intel Firmware Descriptor
(IFD).  If we only want to build coreboot to update the BIOS section,
all we need is the flash layout.

So add the option to specify the flash layout in the mainboard’s
Kconfig, and thus, to build without the real IFD. However, with such a
build, one has to make sure that the IFD section on the flash ROM will
not be written over (nor any other section that has not been included
by coreboot). A patch to write selected sections of a flash ROM with
IFD has been sent to the flashrom mailing list [2].

The same was done in commit a15cd66b [1] (sandybridge: Make build
possible without descriptor.bin) for Intel Sandy Bridge (BD82x6x).

Edward O'Callaghan b0195a3325 build: Pass correct disassembly flags in Clang build
On SVR4-derived platforms, the character `/' is treated as a comment
character, which means that it cannot be used in expressions. The
`--divide' option turns `/' into a normal character. This seems to be
needed with our local build of binutils since we don't yet use the
internal assembler/disassembler of the Clang tooling.
