The function find_fsp() parses the FSP header and returns either a valid
pointer to the FSP_INFO_HEADER or an error code. The caller of
find_fsp() only takes care about a NULL-pointer but not about a possible
error code. This leads to memory access violations in case of error when
FspTempRamInit is called.
To avoid this and to let the user know that there was an error while
parsing the FSP header show an error message and the error code.

This patch adds a new kind of compile-time assertion based on Linux'
compiletime_assert(). The difference to the existing use of
_Static_assert() in coreboot (which should continue to be used where
appropriate) is that this new assertion only hits if the call to it is
not optimized out at compile time. It is therefore ideal to assert that
certain code paths are not included in the image if a certain Kconfig
option is (not) set. For example,
assert(!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE));
can be rewritten as
if (!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE))
dead_code("This code shouldn't be built for config X");
to turn it into a compile-time check.

At process _start, the stack is expected to be aligned to a
16-byte boundary. Upon entry to any function the stack frame
must have the end of any arguments also aligned. In other words
the value of %esp+4 or %rsp+8 is always a multiple of 16 (1).
Align the stack down and change the method for executing
car_stage_entry from jmp to call which should preserve proper
alignment regardless of a 32- or 64-bit build.
Although 4-byte alignment is the minimum requirement for i386,
some AMD platforms use SSE instructions which expect 16-byte.
