introduced a regression where platform-specific ffs/fls implementations
were defined away. This patch corrects that by using PLATFORM_xxx
instead of the name itself.

Move __set/clear_bit from ubifs.h to bitops.h

2009-09-15T20:31:24+00:00

__set_bit and __clear_bit are defined in ubifs.h as well as in
asm/include/bitops.h for some architectures. This patch moves
the generic implementation to include/linux/bitops.h and uses
that unless it's defined by the architecture.

Blackfin: use scratch pad for exception stack

2009-09-02T09:58:38+00:00

If the memory layout pushes the stack out of the default DCPLB coverage,
the exception handler may trigger a double fault by trying to push onto
the uncovered stack.  So handle the exception stack similar to the kernel
by using the top of the scratch pad SRAM.

Blackfin: increase default console size

2009-09-02T09:58:38+00:00

The default console size indirectly applies to length of env vars, so a
smaller length makes it hard to pass longer command lines to kernels.

Blackfin: change global data register from P5 to P3

2009-09-02T09:14:02+00:00

Since the Blackfin ABI favors higher scratch registers by default, use the
last scratch register (P3) for global data rather than the first (P5).
This allows the compiler's register allocator to use higher number scratch
P registers, which in turn better matches the Blackfin instruction set,
which reduces the size of U-Boot by more than 1024 bytes...

Blackfin: add os log functions

2009-07-19T01:15:50+00:00

Part of the mini Blackfin ABI with operating systems is that they can use
0x4f0-0x4f8 to pass log buffers to/from bootloaders.  So add support to
U-Boot for reading the log buffer.

asm-generic: Consolidate errno.h to asm-generic/errno.h

2009-07-09T12:07:11+00:00

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.

Blackfin: convert specific pre/post config headers to common method

2009-06-15T00:01:13+00:00

The Blackfin port was using asm/blackfin-config-{pre,post}.h to setup
common Blackfin board defines.  The common method now is to use config.h,
so convert blackfin-config-post.h to that.  Rename the still Blackfin
specific blackfin-config-pre.h to config-pre.h so the naming conventions
at least line up.

Blackfin: new spibootldr command

2009-06-15T00:01:04+00:00

Newer Blackfin parts can an on-chip ROM that can boot LDRs over SPI flashes,
so add a new 'spibootldr' command to take advantage of it.
