BCM2708: Add enough infrastructrue (more stubs) to get a clean compilation of the Pi Zero configuration (with many undefined things at link time). BCM2708: Add basic interrupt handling logic BCM2708: Add interrupt register definitions. BCM2708: Add irq.h header file BCM2708/Pi zero: bcm_boot.c and bcm_memorymap.h now compile. Added pizero linker script. BCM2708/Pi Zero: Add Make.defs needed to build. arch/arm/include/bcm2708, arch/arm/src/bcm2708, configs/pizero: Add some basic build and configuration logic. configs/pizero: Add some basic structure of the Rasperry Pi Zero port. Created directory configs/pizero. Nothing there now but a README.txt file. Add initial boot.c and memorymap.c files Author: Alan Carvalho de Assis <acassis@gmail.com> Add AUX/UART/SPI registers definition Author: Alan Carvalho de Assis <acassis@gmail.com> Pizero GPIO registers * Initial commit to add GPIO definitions * Add remaining GPIO registers definition Alan Carvalho de Assis <acassis@gmail.com> BCM2708 memory map: Add VBASE defintions; fix VCSDRAM address per Alan; move all virtual address to the bottom of the file to avoid confusion -- top is all physical address; bottom is all veritural address.
