u-boot.git/arch/nios2/include/asm/system.h, branch v2011.06 Unnamed repository; edit this file 'description' to name the repository. nios2: fix out of reach case for do_reset 2010-08-20T02:15:49+00:00 Thomas Chou thomas@wytron.com.tw 2010-08-16T02:49:44+00:00 7a6a7d10e6b96ab4a5c0d8852802ec52be2b582e There is a limitation (or bug?) of nios2 toolchain. The nios2 gcc didn't generate correct code when the reset vector is passed as a constant. It just generated a direct "call", which was wrong when the reset vector was not located in the same 256MB span as u-boot. The "Nios II Processor Reference Handbook" said, "call can transfer execution anywhere within the 256 MByte range determined by PC31..28. The Nios II GNU linker does not automatically handle cases in which the address is out of this range." So we have to use registered "callr" instruction to do the job.

Move architecture-specific includes to arch/$ARCH/include/asm 2010-04-13T07:13:12+00:00 Peter Tyser ptyser@xes-inc.com 2010-04-13T03:28:08+00:00 819833af39a91fa1c1e8252862bbda6f5a602f7b This helps to clean up the include/ directory so that it only contains non-architecture-specific headers and also matches Linux's directory layout which many U-Boot developers are already familiar with.
