2006-01-09[PATCH] powerpc: Remove device_node addrs/n_addrBenjamin Herrenschmidt
The pre-parsed addrs/n_addrs fields in struct device_node are finally gone. Remove the dodgy heuristics that did that parsing at boot and remove the fields themselves since we now have a good replacement with the new OF parsing code. This patch also fixes a bunch of drivers to use the new code instead, so that at least pmac32, pseries, iseries and g5 defconfigs build.

2006-01-09[PATCH] powerpc: Update OF address parsersBenjamin Herrenschmidt
This updates the OF address parsers to return the IO flags indicating the type of address obtained. It also adds a PCI call for converting physical addresses that hit IO space into into IO tokens, and add routines that return the translated addresses into struct resource Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] powerpc: udbg updatesBenjamin Herrenschmidt
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 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] ppc32: m8xx watchdog updateMarcelo Tosatti
This updates m8xx_wdt as follows: 1) Remove now obsolete fpos check in the write() function. The driver is currently non functional due to this bug. 2) Use in/out macros for register access. 3) Allows m8xx_wdt to use a kernel timer instead of the builtin RTC/PIT for keep-alive trigger (which is responsible for servicing the watchdog until an userspace application takes over). For instance Cyclades PRxK boards (MPC 855T based) have a non-functional internal RTC/PIT unit. Behaviour for boards with RTC/PIT is unchaged. 4) The last change required moving the RTCSC register setting code to a weak function which can be overriden by board specific files. Otherwise the timer init code trashes the register making it impossible for m8xx_wdt to detect the situation.

2006-01-09[PATCH] powerpc: convert macio_asic to use prom_parseBenjamin Herrenschmidt

2006-01-09[PATCH] powerpc: Unify udbg (#2)Benjamin Herrenschmidt
This patch unifies udbg for both ppc32 and ppc64 when building the merged achitecture. xmon now has a single "back end". The powermac udbg stuff gets enriched with some ADB capabilities and btext output. In addition, the early_init callback is now called on ppc32 as well, approx. in the same order as ppc64 regarding device-tree manipulations. The init sequences of ppc32 and ppc64 are getting closer, I'll unify them in a later patch. For now, you can force udbg to the scc using "sccdbg" or to btext using "btextdbg" on powermacs. I'll implement a cleaner way of forcing udbg output to something else than the autodetected OF output device in a later patch.

2006-01-07[PATCH] fbcon: donīt call set_par() in fbcon_init() if vc_mode == KD_GRAPHICSKnut Petersen
Nothing prevents a user to modprobe a framebuffer driver from e.g. the xterm prompt. As a result, the set_par() function of the driver will be called from fbcon_init(). This is fatal as a lot of X / framebuffer combinations are unable to recover from set_par() reprogramming the graphics controller in KD_GRAPHICS mode. It is also unnecessary as the set_par() function will be called during a switch to KD_TEXT anyway. Because of this no side effects are possible.

2006-01-06[PATCH] Suspend support for libataJens Axboe
This patch adds suspend patch to libata, and ata_piix in particular. For most low level drivers, they should just need to add the 4 hooks to work. As I can only test ata_piix, I didn't enable it for more though. Suspend support is the single most important feature on a notebook, and most new notebooks have sata drives. It's quite embarrassing that we _still_ do not support this. Right now, it's perfectly possible to suspend the drive in mid-transfer.
