TinyCurses was the first curses implementation for libpayload.
It features low memory consumption, static allocation of larger
data structures (so few or no memory allocation calls) and a
reduced feature set.
config PDCURSES

libpayload's PDCurses port provides a full features curses
implementation, including libpanel, libmenu and libform (which
are taken from ncurses).

Normally, libpayload will initialize console input/output on startup
before the payload itself gets control. This option disables that
behavior and leaves console initialization up to the payload.

help
The alternate character set (ACS) is used for drawing lines and
displaying a couple of other special graphics characters. The
ACS characters generally look good on screen, but can be difficult
to cut and paste from a terminal window to a text editor.
Say 'y' here if you want to always use plain ASCII characters to
approximate the appearance of ACS characters on the serial port
console.

its output would look squeezed into the upper-left corner of the screen.

By default (value of 0), the scale factor is automatically
calculated to ensure at least 130 columns (when possible).
config CBGFX_FAST_RESAMPLE
bool "CBGFX: use faster (less pretty) image scaling"
default n
help
When payloads use the CBGFX library to draw .BMPs on the screen,
they will be resampled with an anti-aliasing filter to scale to the
requested output size. The default implementation should normally be
fast enough, but if desired this option can make it about 50-100%
faster at the cost of quality. (It changes the 'a' parameter in the
Lanczos resampling algorithm from 3 to 2.)
Only affects .BMPs that aren't already provided at the right size.

config RTC_PORT_EXTENDED_VIA
bool "Extended RTC ports are 0x74/0x75"
default n
help
For recent chipsets with 256 NVRAM bytes, you have to access the
upper 128 bytes (128-255) using two different I/O ports,
usually 0x72/0x73.
On some chipsets this can be a different set of ports, though.
The VIA VT8237R for example only recognizes the ports 0x74/0x75
for accessing the high 128 NVRAM bytes (as seems to be the case for
multiple VIA chipsets).
If you want to read or write CMOS bytes on computers with one of
these chipsets, say 'y' here.
