2007-10-04[POWERPC] cpm: Describe multi-user ram in its own device node.Scott Wood1-2/+2
The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.

2007-10-03[POWERPC] cpm_uart: Be an of_platform device when CONFIG_PPC_CPM_NEW_BINDING is set.Scott Wood6-25/+260
The existing OF glue code was crufty and broken. Rather than fix it, it has been removed, and the serial driver now talks to the device tree directly. The non-CONFIG_PPC_CPM_NEW_BINDING code can go away once CPM platforms are dropped from arch/ppc (which will hopefully be soon), and existing arch/powerpc boards that I wasn't able to test on for this patchset get converted (which should be even sooner).

2007-09-28[POWERPC] Fix cpm_uart driver for cpm1 machinesJochen Friedrich1-1/+1
in cpm_uart_cpm1.h, DPRAM_BASE is assigned an address derived from cpmp. On ARC=ppc, this is a physical address with 1:1 DMA mapping which can't be used for arithmetric compare operations with virtual addresses returned by cpm_dpram_addr.

2007-05-09[POWERPC] Change rheap functions to use ulongs instead of pointersTimur Tabi2-4/+4
The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

Recent update of asm-powerpc/io.h caused cpm-related stuff to break in the current kernel. Current patch fixes it, as well as other inconsistencies expressed, that do not permit targets from working properly: - Updated dts with a chosen node with interrupt controller, - fixed messed device IDs among CPM2 SoC devices, - corrected odd header name and fixed type in defines, - Added 82xx subdir to the powerpc/platforms Makefile, missed during initial commit, - new solely-powerpc header file for 8260 family (was using one from arch/ppc, this one cleaned up from the extra stuff), in fact for now a placeholder to get the board-specific includes for stuff not yet capable to live with devicetree peeks only - Fixed couple of misprints in reference mpc8272 dts.

The SMC and SCC hardware transmitter is enabled at the wrong place. Simply writing twice to the non-console port, like $ echo asdf > /dev/ttyCPM1 $ echo asdf > /dev/ttyCPM1 puts the shell into endless uninterruptible sleep, since the transmitter is stopped after the first write, and is not enabled before the shutdown function of the second write.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells1-8/+8
Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

2006-09-21POWERPC: Bring the fs_no calculation to the relevant SoC enumerationVitaly Bordug1-3/+6
The fs_no mean used to be fs_enet driver driven, hence it was an enumeration across all the possible fs_enet "users" in the SoC. Now, with QE on the pipeline, and to make DTS descriptions more clear, fs_no features relevant SoC part number, with additional field to describe the SoC type. Another reason for that is now not only fs_enet is going to utilize those stuff. There might be UART, HLDC, and even USB, so to prevent confusion and be ready for upcoming OF_device transfer, fs_enet and cpm_uart drivers were updated in that concern, as well as the relevant DTS.

2006-09-21POWERPC: Get rid of remapping the whole immrVitaly Bordug2-44/+88
The stuff below cleans up the code attempting to remap the whole cpm2_immr early, as well as places happily assuming that fact. This is more like the 2.4 legacy stuff, and is at least confusing and unclear now. To keep the world comfortable, a new mechanism is introduced: before accessing specific immr register/register set, one needs to map it, using cpm2_map(<reg>), for instance, access to CPM command register will look like volatile cpm_cpm2_t *cp = cpm2_map(im_cpm); keeping the code clear, yet without "already defined somewhere" cpm2_immr. So far, unmapping code is not implemented, but it's not a big deal to add it, if the whole idea makes sense. Signed-off-by: Vitaly Bordug <vbordug@ru.mvista.com>

2005-08-31[SERIAL] Clean up and fix tty transmission start/stopingRussell King1-4/+4
The start_tx and stop_tx methods were passed a flag to indicate whether the start/stop was from the tty start/stop callbacks, and some drivers used this flag to decide whether to ask the UART to immediately stop transmission (where the UART supports such a feature.) There are other cases when we wish this to occur - when CTS is lowered, or if we change from soft to hard flow control and CTS is inactive. In these cases, this flag was false, and we would allow the transmitter to drain before stopping. There is really only one case where we want to let the transmitter drain before disabling, and that's when we run out of characters to send. Hence, re-jig the start_tx and stop_tx methods to eliminate this flag, and introduce new functions for the special "disable and allow transmitter to drain" case.

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!
