[Thomas: - addition of 'depends on BR2_arm' as suggested by Yann. - addition of a comment in the Config.in help text that says that this library is a pure abomination. - fix the hash, since apparently upstream changes the released tarballs after they are published. - fix license, it's GPLv2, not GPLv2+.] Signed-off-by: Peter Seiderer <ps.report@gmx.net> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

C library for Broadcom BCM 2835 as used in Raspberry Pi.
|
|
It provides access to GPIO and other IO functions on the
|
|
Broadcom BCM 2835 chip, allowing access to the GPIO pins
|
|
on the 26 pin IDE plug on the RPi board so you can control
|
|
and interface with various external devices.
|
|
|
|
WARNING: the opinion of the Buildroot developers is that
|
|
such library is a complete abomination as it entirely works
|
|
around the standard Linux interfaces to access GPIOs, I2C,
|
|
SPI busses or other IOs. The library directly remaps the
|
|
hardware registers in user-space, completely bypassing what
|
|
the kernel drivers are doing, and potentially conflicting
|
|
with them.
