Martin Roth baba3e9610 console: Update for vboot before bootblock
Exclude pieces of console code from the vboot if running before
bootlock.  The PSP verstage code will re-implement some of
these in its own code.

Kyösti Mälkki 5d0893adce console, PCI: Remove EARLY_PCI_BRIDGE support in verstage
The purpose of pci_early_bridge_init() is to temporarily configure
PCIe rootport (or PCI bridge) on bus 0 to configure PCI device BARs
on the secondary bus. Currently used and tested only with UART_OXPCIE.

Since those BARs do not reset on stage changes, it is not necessary
to redo those steps for verstage or postcar. Note that the option
does not really work with many of the later platforms where PCIe
pins/links/lanes are configured late in FSP-M or similar blob.

Patrick Georgi 6b5bc77c9b treewide: Remove "this file is part of" lines
Stefan thinks they don't add value.

Command used:
sed -i -e '/file is part of /d' $(git grep "file is part of " |egrep ":( */\*.*\*/\$|#|;#|-- | *\* )" | cut -d: -f1 |grep -v crossgcc |grep -v gcov | grep -v /elf.h |grep -v nvramtool)

The exceptions are for:
 - crossgcc (patch file)
 - gcov (imported from gcc)
 - elf.h (imported from GNU's libc)
 - nvramtool (more complicated header)

Julius Werner 540a98001d printf: Automatically prefix %p with 0x
According to the POSIX standard, %p is supposed to print a pointer "as
if by %#x", meaning the "0x" prefix should automatically be prepended.
All other implementations out there (glibc, Linux, even libpayload) do
this, so we should make coreboot match. This patch changes vtxprintf()
accordingly and removes any explicit instances of "0x%p" from existing
format strings.

How to handle zero padding is less clear: the official POSIX definition
above technically says there should be no automatic zero padding, but in
practice most other implementations seem to do it and I assume most
programmers would prefer it. The way chosen here is to always zero-pad
to 32 bits, even on a 64-bit system. The rationale for this is that even
on 64-bit systems, coreboot always avoids using any memory above 4GB for
itself, so in practice all pointers should fit in that range and padding
everything to 64 bits would just hurt readability. Padding it this way
also helps pointers that do exceed 4GB (e.g. prints from MMU config on
some arm64 systems) stand out better from the others.

Jacob Garber 4c33a3aaa3 src: Make implicit fall throughs explicit
Implicit fall throughs are a perpetual source of bugs and Coverity Scan
issues, so let's squash them once and for all. GCC can flag implicit fall
throughs using the -Wimplicit-fallthrough warning, and this should
ensure no more enter the code base. However, many fall throughs are
intentional, and we can use the following comment style to have GCC
suppress the warning.

    switch (x) {
    case 1:
            y += 1;
	    /* fall through */
    case 2:
            y += 2;
	    /* fall through - but this time with an explanation */
    default:
            y += 3;
    }

This patch adds comments for all remaining intentional fall throughs,
and tweaks some existing fall through comments to fit the syntax that
GCC expects.

Jacob Garber 5b9948140f console: Correct printing of hexadecimal integers
Commit b19946cc62 (console: Remove support for printing extra bases)
truncated the digits string to only print integers of up to base 16.
However, that string was also used to print the leading 'x' or 'X' for
hexadecimal integers and is now too short. Fix this to prevent an out
of bounds read.

Joel Kitching 393c71c213 add ctype.h header
Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files.  When
these headers don't line up with C Standard Library, it causes
problems.

Create ctype.h header file.  Relocate ctype.h functions from
string.h into ctype.h.  Update source files which call ctype.h
functions accordingly.

Note that ctype.h still lacks five functions which are not used
in coreboot source:
  isalnum, isalpha, iscntrl, isgraph, ispunct

Jacob Garber deb99af8a1 console: Allow using vprintk() with disabled console
The prototype of vprintk() is currently declared unconditionally, which
prevents it from being used in situations where the console is disabled.
The code will compile correctly, but not link, since the definition in
console.c isn't being provided. This adds a shim around the declaration
so that, like printk(), a call to vprintk() in this situation will expand
to a no-op function instead.

Jacob Garber 913437e8a2 console: Make die() and friends variadic
die() currently only accepts a fixed message string, which is rather
inconvenient when there is extra information that would be helpful to
print in the error message. This currently requires an extra call to
printk(), which is somewhat awkward:

    printk(BIOS_EMERG, "Bad table, opcode %d at %d", id, i);
    die("");	// what do I say here?

die() already has a printk() inside it to print the error message, so
let's just make it variadic to combine the two.

    die("Bad table, opcode %d at %d", id, i);	// much better

Forwarding variadic arguments from one function to another is rather
tricky, so die_with_post_code() is redefined as a variadic macro
instead.

don't want a huge fully-featured string parsing library in coreboot,
being able to parse an integer is occasionally useful.
