[POWERPC] Use udbg_early_init() on ppc32

2007-02-14T00:55:16Z

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

2006-06-28T01:59:48Z

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. Signed-off-by: Michael Ellerman Signed-off-by: Paul Mackerras

[PATCH] powerpc: Add udbg-immortal kernel option

2006-06-09T11:24:10Z

When debugging early kernel crashes that happen after console_init() and before a proper console driver takes over, we often have to go hack into udbg.c to prevent it from unregistering so we can "see" what is happening. This patch adds a kernel command line option "udbg-immortal" instead to avoid having to modify the kernel. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Paul Mackerras

[PATCH] powerpc: Make early debugging configurable via Kconfig

2006-01-11T03:48:26Z

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: Experimental support for new G5 Macs (#2)

2006-01-09T04:03:17Z

This adds some very basic support for the new machines, including the Quad G5 (tested), and other new dual core based machines and iMac G5 iSight (untested). This is still experimental ! There is no thermal control yet, there is no proper handing of MSIs, etc.. but it boots, I have all 4 cores up on my machine. Compared to the previous version of this patch, this one adds DART IOMMU support for the U4 chipset and thus should work fine on setups with more than 2Gb of RAM.
