This is libpayload, a minimal library to support standalone payloads
|
||||||
|
that can be booted with firmware like coreboot. It handles the setup
|
||||||
|
code, and provides common C library symbols such as malloc() and
|
||||||
|
printf().
|
||||||
|
|
||||||
|
Please see the sample/ directory for an example of the payload in

* This is a tiny implementation of the (n)curses library intended to be
|
||||||
|
* used in embedded/firmware/BIOS code where no libc or operating system
|
||||||
|
* environment is available and code size is very important.
|
||||||
|
*
|
||||||
|
* Design goals:
|
||||||
|
* - Small object code.
|
||||||
|
* - Self-contained.
|
||||||
|
* - Doesn't require a libc (no glibc/uclibc/dietlibc/klibc/newlib).
|
||||||
|
* - Works without any other external libraries or header files.
|
||||||
|
* - Works without an underlying operating system.
|
||||||
|
* - Doesn't use files, signals, syscalls, ttys, library calls, etc.
|
||||||
|
* - Doesn't do any dynamic memory allocation (no malloc() and friends).
|
||||||
|
* - All data structures are statically allocated.
|
||||||
|
* - Supports standard VGA console (80x25) and serial port console.
|
||||||
|
* - This includes character output and keyboard input over serial.
|
||||||
|
* - Supports beep() through a minimal PC speaker driver.
|
||||||
|
*
|
||||||
|
* Limitations:
|
||||||
|
* - Only implements a small subset of the (n)curses functions.
|
||||||
|
* - Only implements very few sanity checks (for smaller code).
|
||||||
|
* - Thus: Don't do obviously stupid things in your code.
|
||||||
|
* - Doesn't implement the 'form', 'panel', and 'menu' extentions.
|
||||||
|
* - Only implements C bindings (no C++, Ada95, or others).
|
||||||
|
* - Doesn't include wide character support.
