powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00+00:00

from include/asm-powerpc.  This is the result of a

mkdir arch/powerpc/include/asm
git mv include/asm-powerpc/* arch/powerpc/include/asm

Followed by a few documentation/comment fixups and a couple of places
where  was being used explicitly.  Of the latter only
one was outside the arch code and it is a driver only built for powerpc.

[POWERPC] 4xx: Add early udbg support for 40x processors

2007-12-23T19:13:03+00:00

This adds some basic real mode based early udbg support for 40x
in order to debug things more easily

[POWERPC] Add early debug console for CPM serial ports.

2007-10-04T01:35:43+00:00

This code assumes that the ports have been previously set up, with
buffers in DPRAM.

[POWERPC] Early serial debug support for PPC44x

2007-05-08T04:47:33+00:00

This adds support for early serial debugging via the built in
port on IBM/AMCC PowerPC 44x CPUs.  It uses a bolted TLB entry in
address space 1 for the UART's mapping, allowing robust debugging both
before and after the initialization of the MMU.

[POWERPC] Use udbg_early_init() on ppc32

2007-02-14T00:55:16+00:00

udbg_early_init() is a function used on 64 bit systems, which
initializes whichever early udbg backend is configured.  This function
is not called on 32-bit, however if btext early debug is enabled it
does have an explicit, inline, #ifdef-ed assignment performing
analagous initialization.

This patch makes things more uniform by folding the btext
initialization as an option into udbg_early_init() and calling that
from the 32-bit setup path.

[POWERPC] Add udbg support for RTAS console

2006-06-28T01:59:48+00:00

Add udbg hooks for the RTAS console, based on the RTAS put-term-char
and get-term-char calls. Along with my previous patches, this should
enable debugging as soon as early_init_dt_scan_rtas() is called.

[PATCH] powerpc: udbg_printf() formatting attribute

2006-05-19T05:02:19+00:00

This patch allows the compiler to catch any printf-like mismatches for
udbg_printf().  After some brute force building I've only found issues
with my own code and lparcfg.c It could break some developers, but
IMHO that would be goodness.

[PATCH] powerpc: Make early debugging configurable via Kconfig

2006-01-11T03:48:26+00:00

This patch adds Kconfig entries to control the early debugging options,
currently in setup_64.c.

Doing this via Kconfig rather than #defines means you can have one source tree,
which is buildable for multiple platforms - and you can enable the correct
early debug option for each platform via .config.

I made udbg_early_init() a static inline because otherwise GCC is to daft to
optimise it away when debugging is off.

Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.
