* 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>

* SPARC BSPs: implemented shared-irq using libbsp/shared layerDaniel Hellstrom2012-04-0623-4/+634
| | | | | | | | | | | | | | | 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. Added support for the LEON3 extended interrupt controller when using the shared IRQ layer. ERC32 patches untested. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Regenerate
* LEON3: console use register pointers instead of UART indexesDaniel Hellstrom2012-04-052-33/+33

* 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.

* bsps: More accurate PowerPC clock driverSebastian Huber2012-04-027-20/+47
| | | | | | The clock driver used previously the bsp_clicks_per_usec value. For a 33333333Hz time base frequency this leads to a relative error of one per cent for example due to integer truncation.

* Add Virtex4 and Virtex5 BSPsRic Claus2012-03-3031-0/+4201
| | | | | | | | | | | | | | | | | This commit covers at least PR2020, 2022, and 2023. This patch adds all of the code for both BSPs, modifications to libcpu/powerpc for the ppc440, and some updates to the BSPs from follow up review and testing. These BSPs should be good baselines for future development. The configurations used by Ric are custom and have a non-standard NIC. They also do not have a UART. Thus the current console driver just prints to a RAM buffer. The NIC and UART support are left for future work. When the UART support is added, moving the existing "to RAM" console driver to a shared location is likely desirable because boards with no debug UART port are commonly deployed. This would let printk() go to RAM.

* | SPARC: bsp_early_malloc() routine for startup memory allocationDaniel Hellstrom2012-03-298-13/+80
| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>

* | 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>
