Martin Roth 65244a7f66 AUTHORS: Move src/console copyrights into AUTHORS file
As discussed on the mailing list and voted upon, the coreboot project
is going to move the majority of copyrights out of the headers and into
an AUTHORS file.  This will happen a bit at a time, as we'll be unifying
license headers at the same time.

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

Julius Werner 66c77c2dc9 console: Move poor-man's atoi() into string.h
vtxprintf.c seems to have been written before string.h was as fleshed
out as it is today -- this patch removes some custom implementation of
stuff we now have globally. It also makes the skip_atoi() function
globally available, because I need it somewhere else, and while we maybe
don't want a huge fully-featured string parsing library in coreboot,
being able to parse an integer is occasionally useful.

benefit of the warning outweighs the occasional weirdness.

Ronald G. Minnich 79e36d9060 Improve how our printk calls do_div by using constants.
The do_div code has a nice optimization in it when it is called with
constants. The current highly generalized use of it defeats those
optimizations and causes trouble on ARM, resulting in a complex and
buggy code path.

Since we only need to print in bases 8, 10, and 16, do a minor
restructuring of the code so that we call do_div with constants.
If you need base 2, print in base 16 and do it in your head. :-)

This fixes an ongoing problem with ARM, will not harm X86, and will
help PPC should we ever want to support it again.
Plus, I don't have to ever try to understand the div64 assembly and where
it's going wrong :-)
