9172b6920c src: Remove variable length arrays
Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.

	int sum(size_t n) {
		int arr[n];
		...
	}

This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],

    AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
    much _slower_ code (and more fragile code), than just using a fixed
    key size would have done. [...] Anyway, some of these are definitely
    easy to just fix, and using VLA's is actively bad not just for
    security worries, but simply because VLA's are a really horribly bad
    idea in general in the kernel.

This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

868c8074b5 sb/intel/common/spi: Increase flash erase timeout
This patch provides an increased timeout (60ms -> 1s) for SPI
HW-sequencing flash erase operations. Without that the erase for MRC
cache writing on siemens/mc_bdx1 sometimes goes wrong because the
timeout stops waiting for flash cycle completion. It was found
during continuous integration. Investigation showed that the used flash
type takes sporadic (e.g. 5% of the test cycles) more time for completion
of erasing operation if the ambient temperature increases. The measured
time values are in range of data sheet of SPI flash. 60ms is a typical
value. So increasing the value is necessary.

tested on siemens/bdx1; measured time values with increased ambient
temperature of flash were always smaller than worst case value of 1s.

b30a47b841 sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supported
The processor P_BLK doesn't support throttling. This behaviour could be
emulated with SMM, but instead just update the FADT to indicate no support
for legacy I/O based throttling using P_CNT.

We have _PTC defined in SSDT, which should be used in favour of P_CNT by
ACPI aware OS, so this change has no effect on modern OS.

Drop all occurences of p_cnt_throttling_supported and update autoport
to not generate it any more.

e48be35bca southbridge/intel/common/smbus: Add do_i2c_block_write()
Intel Braswell supports i2c block writes using SMBus controller.
This support is missing in actual smbus routines.

Add do_i2c_block_write() which is a based on do_smbus_block_write() but
also write first byte to SMBHSTDAT1.
The caller needs to configure the SMBus controller in i2c mode.

In i2c mode SMBus controller will send the next sequence:
SMBXINTADD, SMBHSTDAT1, SMBBLKDAT .. SMBBLKDAT

To ensure the the command is send over the bus the SMBHSTCMD register must
be written also

BUG=N/A
TEST=Config eDP for LCD display on Facebook FBG-1701

7407210a67 sb/intel/bd82x6x/lpc.c: Remove reinitializing the SPI driver
This was done to update the global variable g_ichspi_lock but this is
now removed in favor of reading the lock bit during runtime instead of
keeping track of the state.

816aaba399 sb/intel/spi: Check for the SPI lock bit during runtime
The SPI swseq controller can be locked in other parts of the code, for
instance when it's locked down in the finalize section. The driver
has to be made aware of that. The simpler solution is to not keep
track of the state and simply read out the lock bit on each SPI
transfer.
