* asm-generic: Consolidate errno.h to asm-generic/errno.hMichal Simek2009-07-09-132/+1
| | | | | | | | | | | | | | | This patch use blackfin errno.h implementation which correspond Linux kernel one. MIPS implemetation is different that's why I keep it. I removed ppc_error_no.h from Marvell boards which was the same too. I have got ack from ppc40x, blackfin, arm, coldfire and avr custodians.

| * AVR32: Move addrspace.h to arch-directory, and move some functions from io.h ↵Olav Morken2009-02-23-37/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to addrspace.h The AVR32A architecture (which AT32UC3A-series is based on) has a different memory layout than the AVR32B-architecture.

Provide a dummy weak alias for boards not implementing this hook. The cost of this is: - 2 bytes for the dummy function (retal 0) - 2 bytes for each unnecessary function call (short rcall) which is a pretty small price to pay for avoiding lots of #ifdef clutter. In this particular case, all boards probably end up slightly smaller because we avoid the conditional checking if the gclk_init symbol is NULL.

The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Hammerhead platform is built around a AVR32 32-bit microcontroller from Atmel. It offers versatile peripherals, such as ethernet, usb device, usb host etc. The board also incooperates a power supply and is a Power over Ethernet (PoE) Powered Device (PD). Additonally, a Cyclone III FPGA from Altera is integrated on the board. The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two DDR2 SDRAM interfaces, which will cover even the most exceptional need of memory bandwidth. Together with the onboard video decoder the board is ready for video processing.
