* Introduce virt_to_phys()Kumar Gala2008-12-15-0/+5
| | | | | | | | | | | | virt_to_phys() returns the physical address given a virtual. In most cases this will be just the input value as the vast majority of systems run in a 1:1 mode. However in systems that are not running this way it should report the physical address or ~0 if no mapping exists for the given virtual address. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* FSL: Moved BR_PHYS_ADDR for localbus to common headerKumar Gala2008-12-04-0/+8
| | | | | | | | | | | The BR_PHYS_ADDR macro is useful on all machines that have local bus which is pretty much all 83xx/85xx/86xx chips. Additionally most 85xx & 86xx will need it if they want to support 36-bit physical addresses. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Andy Fleming <afleming@freescale.com>

* | ppc4xx: PPC44x MQ initializationYuri Tikhonov2008-10-17-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the MQ Read Passing & MCIF Cycle limits to the recommended by AMCC values. This fixes the occasional 440SPe hard locking issues when the 440SPe's dedicated DMA engines are used (e.g. by the h/w accelerated RAID driver). Previously the appropriate initialization had been made in Linux, by the ppc440spe ADMA driver, which is wrong because modifying the MQ configuration registers after normal operation has begun is not supported and could have unpredictable results. Comment from Stefan: This patch doesn't change the resulting value of the MQ registers. It explicitly sets/clears all bits to the desired state which better documents the resulting register value instead of relying on pre-set default values.

* | 85xx: Using proper I2C source clock divider for MPC8544Kumar Gala2008-10-17-1/+1
|/ | | | | | | | | | The MPC8544 RM incorrect shows the SEC_CFG bit in PORDEVSR2 as being bit 26, instead it should be bit 28.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Record the Arbiter Event Register values and optionally display them. The Arbiter Event Register can record the type and effective address of an arbiter error, even through an HRESET. This patch stores the values in the global data structure. Display of the Arbiter Event registers immediately after the RSR value can be enabled with defines. The Arbiter values will only be displayed if an arbiter event has occured since the last Power On Reset, and either of the following defines exist: #define CONFIG_DISPLAY_AER_BRIEF - display only the arbiter address and and type register values #define CONFIG_DISPLAY_AER_FULL - display and interpret the arbiter event register values Address Only transactions are one of the trapped events that can register as an arbiter event. They occur with some cache manipulation instructions if the HID0_ABE (Address Broadcast Enable) is set and the memory region has the MEMORY_COHERENCE WIMG bit set. Setting: #define CONFIG_MASK_AER_AO - prevents the arbiter from recording address only events, so that it can still capture other real problems.

* | ppc4xx: Rework 440GX UIC handlingStefan Roese2008-07-11-46/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the 440GX interrupt handling so that the common 4xx code can be used. The 440GX is an exception to all other 4xx variants by having the cascading interrupt vectors not on UIC0 but on a special UIC named UICB0 (UIC Base 0). With this patch now, U-Boot references the 440GX UICB0 when UIC0 is selected. And the common 4xx interrupt handling is simpler without any 440GX special cases. Also some additional cleanup to cpu/ppc4xx/interrupt.c is done. Signed-off-by: Stefan Roese <sr@denx.de>
* | ppc4xx: Consolidate PPC4xx UIC definesStefan Roese2008-07-11-412/+236
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This 2nd patch now removes all UIC mask bit definition. They should be generated from the vectors by using the UIC_MASK() macro from now on. This way only the vectors need to get defined for new PPC's. Also only the really used interrupt vectors are now defined. This makes definitions for new PPC versions easier and less error prone. Another part of this patch is that the 4xx emac driver got a little cleanup, since now the usage of the interrupts is clearer. Signed-off-by: Stefan Roese <sr@denx.de>

The MMODE and MEMODE registers are unified with their peer values used for the INITPLR MR and EMR registers, respectively. Finally, a spelling typo is correct (MANUEL to MANUAL). With these mnemonics in place, the CFG_SDRAM0_* magic numbers for Kilauea are replaced by equivalent mnemonics to make it easier to compare and contrast other 405EX(r)-based boards (e.g. during board bring-up). Finally, unified the SDRAM controller register dump routine such that it can be used across all processor variants that utilize the IBM DDR2 SDRAM controller core. It produces output of the form: PPC4xx IBM DDR2 Register Dump: ... SDRAM_MB0CF[40] = 0x00006701 ... which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included since it is not uncommon that the DCR values in header files get mixed up and it helps to validate, at a glance, they match what is printed in the user manual.

Its present value on the 405EX(r) causes a read back of 0xFFFFFFFF which causes SDRAM initialization to periodically fail since it can prematurely indicate SDRAM ready status.

| | | | | | | | | | | | | | | | | | | | | | | | | | Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM. To support such configurations, we "only" map the first 2GB via the TLB's. We need some free virtual address space for the remaining peripherals like, SoC devices, FLASH etc. Note that ECC is currently not supported on configurations with more than 2GB SDRAM. This is because we only map the first 2GB on such systems, and therefore the ECC parity byte of the remaining area can't be written. Signed-off-by: Stefan Roese <sr@denx.de>
