Klaus Schnass 2c6b33ce3e Libpayload fixes to prevent triple-faults when running in QEMU.
Let the linker figure out the correct address and just CALL the
start_main entry point.

Uwe Hermann 30d789bcbd Fix the NVRAM access functions to work correctly for the
upper 128 bytes of NVRAM (if enabled).

For most chipsets this means using I/O ports 0x72/0x73, but at least
on some VIA chipsets (I tested the VIA VT8237R on actual hardware)
these ports won't work and you have to use 0x74/0x75. Thus, make this
a Kconfig option for now.

Jordan Crouse 0e122af465 [libpayload] Work around sign-extending issue
Somewhere characters are getting sign-extended, meaning that the
attributes of the drawing chars (>= 128) are wrong. Cast the value
before sending it to VGA.

Uwe Hermann 408c4e1784 Drop -Os in libpayload for now, it causes run-time problems for some

arguments to the VIDEO() macro in the right order.

 - get_cpu_speed() didn't return a value.

 - The line

   should actually be

Jordan Crouse 2c7bb9e84f libpayload: Add -Os to the CFLAGS
Adding -Os to the CFLAGS gains us about 25% smaller code (give or take).
Unfortunately, it exposes a strange issue where strcpy() suddenly goes
missing - we think that strcpy() is being provided by libgcc, and that
for some reason, -Os changes the beahavior.  Oh, well - add a quick
strcpy() function and we're good.
