This patch implements the _sbrk_r() system call for Galileo platform. This system call is required by newlib's malloc() implementation. Next patch will introduce the initial support for stdio library which requires a working malloc() function for proper operation. We are not sure about the heap size we should use. Preliminary tests have shown that stdio library requests 1032 bytes heap. So, as an initial guess, a 2Kb heap size should be enough for now.
The Contiki Operating System
Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.
Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
