From: Guan Xuetao <guanxuetao@xxxxxxxxxxxxxxx> The whole patch could be fetched from: git://git.kernel.org/pub/scm/linux/kernel/git/epip/unicore32.git with branch name: unicore32. And it is divided into three patch sets: core architecture files, additional architecture files, and machine related files. This patch set adds the core architecture support for UniCore32 ISA. Patch 1 implements build infrastructure. Patch 2 includes some generic headers stuff. Because all one-line asm-generic headers are auto-generated by ASM_GENERIC_HEADERS in arch/unicore32/Makefile, so the rest seems very little. ELF handling functions are also here. Patch 3 includes processor and system headers. System call interface is here. We used the similar syscall interface as ARM formerly, so the similar calls.S, unistd.h and sys_unicore.c. While we are defining new ABI, it will use the syscall numbers in asm-generic/unistd.h. Patch 4 implements low level entry and setup codes. Patch 5 implements process/thread related codes. Backtrace and stacktrace are here. Patch 6 includes generic codes of memory management. Patch 7 implements fault handling of memory management. Patch 8 implements consistent device DMA handling of memory management. DMA device operations are also here. Patch 9 implements timer and time. RTC and PWM device drivers are also here. Patch 10 implements interrupts and gpio. UniCore32 has 9 gpio interrupt sources. And gpio device operations are also here. Patch 11 implements signals. Patch 12 implements booting process before uncompressed.
