2006-02-10[PATCH] powerpc: trivial: modify comments to refer to new location of filesJon Mason
This patch removes all self references and fixes references to files in the now defunct arch/ppc64 tree. I think this accomplises everything wanted, though there might be a few references I missed. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-11-07[PATCH] ppc32: Allow ERPN for early serial to depend on CPU typeRoland Dreier
The PowerPC 440SPe supports up to 16 GB of RAM, and therefore its IO registers are at 0x4_xxxx_xxxx instead of being at 0x1_xxxx_xxxx like most other PPC 440 chips. To allow for this, this patch moves the definition of the ERPN used for mapping UART0 from being hard-coded in the head_44x.S assembly code to being defined in ibm44x.h.

2005-10-20[PATCH] ppc32: replace use of _GLOBAL with .globl for ppc32Kumar Gala
The _GLOBAL() macro is for text symbols only. Changed to using .globl for .data symbols. This is also needed in ppc32 land to allow FSL Book-E, 40x, and 44x to work. Signed-off-by: Kumar K. Gala <kumar.gala@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2005-10-01powerpc: merge idle_power4.S and trapc.sStephen Rothwell
Use idle_power4.S from ppc64 as we are not going to support 32 bit power4 in the merged tree. Merge ppc64 traps.c into powerpc traps.c: use ppc64 versions of exception routine names (as they don't have StudlyCaps) make all the versions if die() have the same prototype Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au>

2005-09-05[PATCH] ppc32: Added support for the Book-E style Watchdog TimerKumar Gala
PowerPC 40x and Book-E processors support a watchdog timer at the processor core level. The timer has implementation dependent timeout frequencies that can be configured by software. One the first Watchdog timeout we get a critical exception. It is left to board specific code to determine what should happen at this point. If nothing is done and another timeout period expires the processor may attempt to reset the machine. Command line parameters: wdt=0 : disable watchdog (default) wdt=1 : enable watchdog wdt_period=N : N sets the value of the Watchdog Timer Period. The Watchdog Timer Period meaning is implementation specific. Check User Manual for the processor for more details. This patch is based off of work done by Takeharu Kato.

2005-08-01[PATCH] ppc32: add 440ep supportMatt Porter
Add PPC440EP core support. PPC440EP is a PPC440-based SoC with a classic PPC FPU and another set of peripherals.

2005-07-30[PATCH] ppc32: fix 44x early serial debug for configurations with more than ↵Eugene Surovegin
512M of RAM Fix 44x early serial debugging for big RAM configurations (more than 512M). We cannot use default OpenBIOS virtual mapping, because it interferes with pinned TLB entry. While we are at it, move early UART mapping to TLB slot 0, so it can survive longer during boot process (slot 1 is used by the first ioremap call, effectively killing UART mapping if it occupies this slot). Also, change UART TLB entry size to 4K (256M is too much for a bunch of registers :). Squash some warnings on the way. Tested on Ebony and Ocotea with 1G of RAM. Thanks to Scott Coulter <scott.coulter@cyclone.com> for diagnosing this problem.

2005-05-20[PATCH] ppc32: fix CONFIG_TASK_SIZE handling on 44xMatt Porter
This patch fixed CONFIG_TASK_SIZE handling on 44x. Currently head_44x.S hardcodes 0x80000000, which breaks if user chooses to change TASK_SIZE (e.g. for 3G user-space). Tested on Ocotea in 3G/1G configuration.

2005-05-01[PATCH] ppc32: refactor FPU exception handlingPaul Mackerras
Moved common FPU exception handling code out of head.S so it can be used by several of the sub-architectures that might of a full PowerPC FPU. Also, uses new CONFIG_PPC_FPU define to fix alignment exception handling for floating point load/store instructions to only occur if we have a hardware FPU.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
