avr32: remove support for AVR32 architecture

2017-05-01T07:27:15+00:00

This patch drops support for AVR32 architecture from the Linux kernel. The AVR32 architecture is not keeping up with the development of the kernel, and since it shares so much of the drivers with Atmel ARM SoC, it is starting to hinder these drivers to develop swiftly. Also, all AVR32 AP7 SoC processors are end of lifed from Atmel (now Microchip). Finally, the GCC toolchain is stuck at version 4.2.x, and has not received any patches since the last release from Atmel; 4.2.4-atmel.1.1.3.avr32linux.1. When building kernel v4.10, this toolchain is no longer able to properly link the network stack. Haavard and I have came to the conclusion that we feel keeping AVR32 on life support offers more obstacles for Atmel ARMs, than it gives joy to AVR32 users. I also suspect there are very few AVR32 users left today, if anybody at all.

avr32: Fix wrong I/O access size in __raw_readsb

2008-06-27T13:07:50+00:00

__raw_readsb() should always use byte accesses, never halfword accesses, to I/O memory. Signed-off-by: Haavard Skinnemoen

AVR32: Add missing return instruction in __raw_writesb

2006-11-06T13:07:16+00:00

__raw_writesb ends with a conditional branch, which is obviously wrong. It should return after the last loop terminates. Signed-off-by: Haavard Skinnemoen

[PATCH] AVR32: Implement and export __raw_{read,write}s[bwl]

2006-10-26T03:26:33+00:00

Implement __raw_readsb and __raw_writesb. Export __raw_reads[bwl] and __raw_writes[bwl] for use by modules. Signed-off-by: Haavard Skinnemoen Signed-off-by: Linus Torvalds
