avr32/lib: fix unaligned memcpy where len < 4

2009-07-27T10:37:28+00:00

in case of memcpy(p, unaligned, 1..3) we get 1..3 as the
return value instead of p

avr32/lib: fix unaligned memcpy()

2009-07-27T10:37:27+00:00

memcpy(p, unaligned, 4..) returns (p + num_of_unaligned_by_copied)
instead of p because p is not preserved in the unaligned case.

Noticed by Herbert Xu's superior parameter recycling coding technique
which let the md4 self-test fail on avr32.

avr32: Fix out-of-range rcalls in large kernels

2009-01-16T08:31:57+00:00

Replace handcoded rcall instructions with the call pseudo-instruction.
For kernels too far over 1MB the rcall instruction can't reach and
linking will fail.  We already call the final linker with --relax which
converts call pseudo-instructions to the right things anyway.

This fixes

arch/avr32/kernel/built-in.o: In function `syscall_exit_work':
(.ex.text+0x198): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `schedule' defined in .sched.text section in kernel/built-in.o
arch/avr32/kernel/built-in.o: In function `fault_exit_work':
(.ex.text+0x3b6): relocation truncated to fit: R_AVR32_22H_PCREL against symbol `schedule' defined in .sched.text section in kernel/built-in.o

But I'm still left with

arch/avr32/kernel/built-in.o:(.fixup+0x2): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+45a
arch/avr32/kernel/built-in.o:(.fixup+0x8): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+8ea
arch/avr32/kernel/built-in.o:(.fixup+0xe): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+abe
arch/avr32/kernel/built-in.o:(.fixup+0x14): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ac8
arch/avr32/kernel/built-in.o:(.fixup+0x1a): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ad2
arch/avr32/kernel/built-in.o:(.fixup+0x20): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+adc
arch/avr32/kernel/built-in.o:(.fixup+0x26): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+ae6
arch/avr32/kernel/built-in.o:(.fixup+0x2c): relocation truncated to fit: R_AVR32_22H_PCREL against `.text'+af0
arch/avr32/kernel/built-in.o:(.fixup+0x32): additional relocation overflows omitted from the output

These are caused by a similar problem with 'rjmp' instructions.
Unfortunately, there's no easy fix for these at the moment since we
don't have a arbitrary-range 'jmp' instruction similar to 'call'.

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.

read_current_timer() cleanups

2008-02-06T18:41:02+00:00

- All implementations can be __devinit

- The function prototypes were in asm/timex.h but they all must be the same,
  so create a single declaration in linux/timex.h.

- uninline the sparc64 version to match the other architectures

- Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

[AVR32] Remove last remains of libgcc

Two libgcc headers were left around even though all the actual code
borrowed from libgcc is gone. Delete them.

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.
