2008-03-31Fix the NVRAM access functions to work correctly for theUwe Hermann
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.

2008-03-29[libpayload] Work around sign-extending issueJordan Crouse
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.

2008-03-20libpayload: Add -Os to the CFLAGSJordan Crouse
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.
