* powerpc/fsl_rio: Fix compile warningsKumar Gala2009-05-19
| | | | | | | | | | We we build with resource_size_t as a 64-bit quantity we get: arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_setup': arch/powerpc/sysdev/fsl_rio.c:1029: warning: format '%08x' expects type 'unsigned int', but argument 4 has type 'resource_size_t' arch/powerpc/sysdev/fsl_rio.c:1029: warning: format '%08x' expects type 'unsigned int', but argument 5 has type 'resource_size_t' Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fsl_rio: Pass the proper device to dma mapping routinesAnton Vorontsov2009-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | The driver should pass a device that specifies internal DMA ops, but currently NULL pointer is passed, therefore following bug appears during boot up: ------------[ cut here ]------------ Kernel BUG at c0018a7c [verbose debug info unavailable] Oops: Exception in kernel mode, sig: 5 [#1] [...] NIP [c0018a7c] fsl_rio_doorbell_init+0x34/0x60 LR [c0018a70] fsl_rio_doorbell_init+0x28/0x60 Call Trace: [ef82bda0] [c0018a70] fsl_rio_doorbell_init+0x28/0x60 (unreliable) [ef82bdc0] [c0019160] fsl_rio_setup+0x6b8/0x84c [ef82be20] [c02d28ac] fsl_of_rio_rpn_probe+0x30/0x50 [ef82be40] [c0234f20] of_platform_device_probe+0x5c/0x84 [...] ---[ end trace 561bb236c800851f ]--- This patch fixes the issue.

* [RAPIDIO] Change RapidIO doorbell source and target ID field to 16-bitZhang Wei2008-04-29
| | | | | | | | | Change RapidIO doorbell source and target ID field to 16-bit for support large system size, which max rio devid is 65535. Signed-off-by: Zhang Wei <wei.zhang@freescale.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Paul Mackerras <paulus@samba.org>

* [RAPIDIO] Auto-probe the RapidIO system sizeZhang Wei2008-04-29
| | | | | | | | | | The RapidIO system size will auto probe in RIO setup. The route table and rionet_active in rionet.c are changed to be allocated dynamically according to the size of the system.

* [RAPIDIO] Add OF-tree support to RapidIO controller driverZhang Wei2008-04-29
| | | | | | | | | | This initializes the RapidIO controller driver using addresses and interrupt numbers obtained from the firmware device tree, rather than using hardcoded constants.

* [RAPIDIO] Add RapidIO multi mport supportZhang Wei2008-04-29
| | | | | | | | | | | | | | The original RapidIO driver suppose there is only one mpc85xx RIO controller in system. So, some data structures are defined as mpc85xx_rio global, such as 'regs_win', 'dbell_ring', 'msg_tx_ring'. Now, I changed them to mport's private members. And you can define multi RIO OF-nodes in dts file for multi RapidIO controller in one processor, such as PCI/PCI-Ex host controllers in Freescale's silicon. And the mport operation function declaration should be changed to know which RapidIO controller is target.

* [POWERPC] Move RapidIO support code from arch/ppcKumar Gala2008-01-23
Do just enough to move the RapidIO support code for 85xx over from arch/ppc into arch/powerpc and make it still build. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
