* pci.h cleanup - Consolidate common defines to cpukit pci.hJoel Sherrill2012-05-164-1158/+24
| | | | | | | | | | | | | + libbsp/sparc/shared/include/pci.h was largely a copy of an older version of the cpukit pci.h. Removed much of the contents and included <rtems/pci.h>. + sparc/*/pci*.c - Move to <rtems/pci.h> required updating to use uint32_t for dword accesses. + Rename PCI_MULTI_FUNCTION to PCI_HEADER_TYPE_MULTI_FUNCTION + Define PCI_HEADER_TYPE_MULTI_FUNCTION in cpukit pci.h and remove PCI_MULTI_FUNCTION definitions in C files. + Move PCI_INVALID_VENDORDEVICEID definitions from various C files to cpukit pci.h
* LEON: moved register definitions into grlib header fileDaniel Hellstrom2012-05-1621-134/+153
| | | | | | | | | | | | Some register layout definitions for LEON3 reside in ambapp.h which does not really has anything to do with device registers. The register structures has been incorrectly named LEON3_*, the cores are not only used on LEON3 but on LEON4 and perhaps on LEON5 when that day comes. Some structures has been renamed according to the GRLIB core name instead, which CPU that actually use it is not relevant. Drivers has been updated with the new names.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-1177-168/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

* LEON: updated AMBA PnP APIDaniel Hellstrom2012-04-1719-634/+1839
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old layer had some limitations/problems for multiple AHB buses since the data structure containing all AMBA devices were allocated before scanning. The new layer create devices as they are found and memory is allocated using malloc() or bsp_early_malloc() during booting. The old 8 functions for finding a specific AHB-Slave or APB-Slave device has been replaced with one function, ambapp_for_each(), which iterates over all devices matching the specified search options and calls a user provided function. The new way lowers the footprint and makes searching more flexible. The frequency information is now supported, if the frequency of one device is reported by the user. More AHB-to-AHB bridges are supported. The API has been split into several parts in order to lower the footprint. The API also introduces the AMBAPP CORE concept, where one ambapp_core can be created from one AHB Master, AHB Slave and one APB Slave, at least one device is required for creating a core.

* PR2052: LEON3: fix open_eth interrupt initialization bugDaniel Hellstrom2012-04-101-4/+4

* GRETH: use shared-irq service instead of BSP specific set_vec()Daniel Hellstrom2012-04-061-5/+2
| | | | | | | | | | The ISR code is updated to use argument instead of global greth structure, now that the greth private is available in the ISR. The shared-irq routines will unmask the IRQ, so the forced LEON3 BSP unmask/clear IRQ is removed. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>

| | | | | | | | | | | | | | | The implementation use IRQ number instead of vector number since some IRQs does not have a unique vector, for example the extended interrupts all enter the same trap vector entry.

* LEON3: cleanup console UART indexing handlingDaniel Hellstrom2012-04-052-61/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The UART indexing was rather a mess when MP was enabled. The changes introduces two weak variables syscon_uart_index and debug_uart_index so that the user can override the default system debug console (printk) and system console UART (/dev/console). The two weak variables is updated on boot to reflect the "real" UART index. MINOR DEVICE-FS-NAME UART 0 /dev/console Default /dev/console_a, user selectable 1 /dev/console_a APBUART[0] (missing by default) 2 /dev/console_b APBUART[1] ... /dev/console_a is by default renamed /dev/console and assigned minor=0, but user can select /dev/console_['a'+N] to be renamed to /dev/console by setting syscon_uart_index=N. On a MP system the console renamed to /dev/console is selected by CPU index (LEON3_Cpu_Index). /dev/console_['a' + LEON3_Cpu_Index] is renamed unless overrided. Resource sharing is performed by the user, one should not open/access a console that another OS instance uses. This patch also moves the initialization of the UART to the open() call, note that before APBUART[0] was always enabled as debug uart even on MP systems. The debug UART is initialized at boot time.

| | | | | | | | | | | | If bsp_early_malloc() is called early during boot room will be allocated after BSS END. If the function is called after boot is will call malloc() instead. The returned memory is not freeable and always 8-byte aligned. If the bsp_early_malloc() isn't called the function is not dragged in and the workspace will be unmodified in size.

* GRETH: added support for non-snooping GRETH 10/100 systemsDaniel Hellstrom2012-03-274-0/+24
| | | | | | | | | | | | | | | | | | When data cache snooping is not present the cache needs flushing, the SPARC LEON CPUs does not have to ability to flush individual cache rows and flushing all cache is expensive. Instead the LDA instruction is used to force cache miss on individual loads during the IP-align copy operation required anyway. GRETH GBIT non-snooping systems are still unsupported, since it use zero-copy (can deal with unaligned DMA). Let the bsp.h select if the GRETH driver is supported. Currently only the LEON2/LEON3 platforms BSPs builds the driver. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>

| | | | | | | | | Moved the intelligence whether the driver is supported or not completely to the BSP, now that bsp.h is included (even though it is a driver... hmm).

* LEON3: CPU index intialization moved to bspstart.cDaniel Hellstrom2012-02-022-18/+18
| | | | | | | | | | | | | | | | | PR 2009/bsps All LEON3/4 systems have a CPU-id, if on a single-CPU system the ID is always zero. On a multicore system it ranges from 0 to 15. The CPU index should always by updated even in a non-MP RTEMS OS since the CPU running RTEMS may not always be CPU0. For example when RTEMS runs on CPU1 and Linux on CPU0 in a mixed ASMP system. The old code executed within the IRQ controller initialization code makes no sense since the ASR register is a CPU register, it has nothing to do with AMBA initialization either.

Please see comment per hunk below, One should go through the file to indent delay-slots correctly, I have fixed some in the patch areas. An extra space is added in front of delay slots to indicate a delay slot.
