10
11	The items in this category provide answers to questions
12	commonly asked about BSPs.

14	@section What is a BSP?
15
16	BSP is an acronym for Board Support Package.
17
18	A BSP is a collection of device drivers, startup code, linker scripts,
19	and compiler support files (specs files) that tailor RTEMS for a
20	particular target hardware environment.
21
22	@section What has to be in a BSP?
23
24	The basic set of items is the linker script, bsp_specs, and startup code.
25	If you want standard IO, then you need a console driver. This is needed
26	to run any of the RTEMS tests. If you want to measure passage of time,
27	you need a clock tick driver. This driver is needed for all RTEMS tests
28	EXCEPT hello world and the timing tests. The timer driver is a benchmark
29	timer and is needed for the tmtests (timing tests). Sometimes you will
30	see a shmsupp directory which is for shared memory multiprocessing
31	systems. The network driver and real-time clock drivers are optional
32	and not required by any RTEMS tests.
