[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.

[PATCH] powerpc: sanitize header files for user space includes

2006-01-09T04:13:08+00:00

include/asm-ppc/ had #ifdef __KERNEL__ in all header files that
are not meant for use by user space, include/asm-powerpc does
not have this yet.

This patch gets us a lot closer there. There are a few cases
where I was not sure, so I left them out. I have verified
that no CONFIG_* symbols are used outside of __KERNEL__
any more and that there are no obvious compile errors when
including any of the headers in user space libraries.

[PATCH] powerpc: udbg updates

2006-01-09T03:51:22+00:00

The udbg low level io layer has an issue with udbg_getc() returning a
char (unsigned on ppc) instead of an int, thus the -1 if you had no
available input device could end up turned into 0xff, filling your
display with bogus characters. This fixes it, along with adding a little
blob to xmon to do a delay before exiting when getting an EOF and fixing
the detection of ADB keyboards in udbg_adb.c
