Usha P 5e59a82c27 soc/intel/common: Set controller state to active in uart init
Set the controller state to D0 during the uart init sequence, this
ensures the controller is up and active.

One more argument "const struct device *dev" has been added
to uart_lpss_init function.

BUG=b:135941367
TEST=Verify no timeouts seen during UART controller enumeration
     sequence in CML, ICL and APL platforms

Jacob Garber c43001eb14 vc/amd/cimx/sb800: Remove old strict-aliasing workaround
C strict aliasing rules state that it is undefined behaviour to access
any pointer using another pointer of a different type (with several small
exceptions). Eg.

    uint64_t x = 3;
    uint16_t y = *((uint16_t *)&x);  // undefined behaviour

From an architectural point of view there is often nothing wrong with
pointer aliasing - the problem is that since it is undefined behaviour,
the compiler will often use this as a cop-out to perform unintended or
unsafe optimizations. The "safe" way to perfom the above assignment is
to cast the pointers to a uint8_t * first (which is allowed to alias
anything), and then work on a byte level:

    *((uint8_t *)&y) = *((uint8_t *)&x);
    *((uint8_t *)&y + 1) = *((uint8_t *)&x + 1);

Horribly ugly, but there you go. Anyway, in an attempt to follow these
strict aliasing rules, the ReadMEM() function in SB800 does the above
operation when reading a uint16_t. While perfectly fine, however, it
doesn't have to - all calls to ReadMEM() that read a uint16_t are passed
a uint16_t pointer, so there are no strict aliasing violations to worry
about (the WriteMEM() function is exactly similar). The problem is that
using this unnecessary workaround generates almost 50 false positive
warnings in Coverity. Rather than manually ignore them one-by-one, let's
just remove the workaround entirely. As a side note, this change makes
ReadMEM() and WriteMEM() now match their definitions in the SB900 code.

Jacob Garber 293e6a96a9 nb/amd/pi,sb/amd/sr5650: Remove unnecessary allocation
add_ivrs_device_entries() is a recursive function, and each recursive
call is passed a pointer to a root_level variable declared outside the
function. In an attempt to make the function self-contained, the initial
call is made with the root_level pointer set to NULL, and then the
function attempts to detect this and allocate a root_level variable for
the rest of the calls. This makes memory management very tricky - for
example, the pi code incorrectly attempts to free the root_level
variable at the end of *each* recursive call, which only avoids being a
double-free because free() in coreboot is currently a no-op. Let's
keep life simple and declare root_level as a local variable outside the
first function call instead.

Kyösti Mälkki b7908d2b08 intel/apollolake: Move LPC decode enables to bootblock
Doing this allows to call console_init() earlier in romstage.
This also fixes IO UART in bootblock, although it appears there
is currently no board that was affected.

Jacob Garber 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].
