1 config BR2_PACKAGE_BCM2835
5 C library for Broadcom BCM 2835 as used in Raspberry Pi.
6 It provides access to GPIO and other IO functions on the
7 Broadcom BCM 2835 chip, allowing access to the GPIO pins
8 on the 26 pin IDE plug on the RPi board so you can control
9 and interface with various external devices.
11 WARNING: the opinion of the Buildroot developers is that
12 such library is a complete abomination as it entirely works
13 around the standard Linux interfaces to access GPIOs, I2C,
14 SPI busses or other IOs. The library directly remaps the
15 hardware registers in user-space, completely bypassing what
16 the kernel drivers are doing, and potentially conflicting
