2010-01-05fsl-ddr: Fix power-down timing settingsDave Liu
1. TIMING_CFG_0[ACT_PD_EXIT] was set to 6 clocks, but It should be set to tXP parameter, tXP=max(3CK, 7.5ns) 2. TIMING_CFG_0[PRE_PD_EXIT] was set to 6 clocks, but It should be set to tXP (if MR0[A12]=1) else to tXPDLL parameter We are setting the mode register MR0[A12]='1' Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-01-05ppc/8xxx: Remove is_fsl_pci_agentKumar Gala
All users of is_fsl_pci_agent have been converted to fsl_is_pci_agent that uses the standard PCI programming model to determine host vs agent/end-point. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2010-01-05ppc/8xxx: Don't use pci_cfg on FSL_CORENET platformsKumar Gala
The FSL_CORENET platforms use a completely different means to determine which PCIe port is enabled as well as if its a host or agent/end-point. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-11-12fsl-ddr: Fix the chip-select interleaving issueDave Liu
commit 1542fbdeec0d1e2a6df13189df8dcb1ce8802be3 introduced one new bug to chip-select interleaving. Single DDR controller also can do the chip-select interleaving if there is dual-rank or qual-rank DIMMs. Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-10-16mpc8xxx: improve LAW error messages when setting up DDRPaul Gortmaker
When setting up the LAWs for the DDR, if there was an error, you got the not-so-helpful error text "ERROR" and nothing else. Not only is it non-informative, but it is also pretty frustrating trying to grep for "ERROR" in the source.

Fixing the number of cores in the device tree based on the actual number of cores on the system. With this same device tree image can be used for dual core and single core members of otherwise exactly same SOC. For example: * P2020RDB and P2010RDB * P1020RDB and P1011RDB * MPC8641D and MPC8641 Signed-off-by: Poonam Aggrwal <poonam.aggrwal@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-08ppc/85xx,86xx: Handling Unknown SOC versionPoonam Aggrwal
Incase the system is detected with Unknown SVR, let the system boot with a default value and a proper message. Now with dynamic detection of SOC properties from SVR, this is necessary to prevent a crash.

2009-09-08ppc/8xxx: Refactor code to determine if PCI is enabled & agent/hostKumar Gala
Refactor the code into a simple bitmask lookup table that determines if a given PCI controller is enabled and if its in host/root-complex or agent/end-point mode. Each processor in the PQ3/MPC86xx family specified different encodings for the cfg_host_agt[] and cfg_IO_ports[] boot strapping signals. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-09-08ppc/8xxx: Remove ddr_pd_cntl register since it doesn't existKumar Gala
The ddr_pd_cntl isn't defined in any reference manual and thus we wil remove especially since we set it to 0, which would most likely be its POR value. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-07-2285xx, 86xx: Add common board_add_ram_info()Peter Tyser
Previously, 85xx and 86xx boards would display DRAM information on bootup such as: ... I2C: ready DRAM: Memory controller interleaving enabled: Bank interleaving! 2 GB FLASH: 256 MB ... This patch moves the printing of the DRAM controller configuration to a common board_add_ram_info() function which prints out DDR type, width, CAS latency, and ECC mode. It also makes the DDR interleaving information print out in a more sane manner: ... I2C: ready DRAM: 2 GB (DDR2, 64-bit, CL=4, ECC on) DDR Controller Interleaving Mode: bank FLASH: 256 MB ...

2009-07-01fsl_ddr: Fix DDR3 calculation of rank density with 8GB or moreTimur Tabi
The calculate for rank density in compute_ranksize() for DDR3 used all integers for the expression, so the result was also a 32-bit integer, even though the 'bsize' variable is a u64. Fix the expression to calculate a true 64-bit value. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-06-12fsl-ddr: Fix handling of >4G of memory when !CONFIG_PHYS_64BITKumar Gala
The ddr code computes most things as 64-bit quantities and had some places in the middle that it was using phy_addr_t and phys_size_t. Instead we use unsigned long long through out and only at the last stage of setting the LAWs and reporting the amount of memory to the board code do we truncate down to what we can cover via phys_size_t. This has the added benefit that the DDR controller itself is always setup the same way regardless of how much memory we have. Its only the LAW setup that limits what is visible to the system.

2009-03-30fsl-ddr: Fix two bugs in the ddr infrastructureDave Liu
1. wr_lat UM said the total write latency for DDR2 is equal to WR_LAT + ADD_LAT, the write latency is CL + ADD_LAT - 1. so, the WR_LAT = CL - 1; 2. rd_to_pre we missed to add the ADD_LAT for DDR2 case.

2009-02-16fsl-ddr: Allow system to boot if we have more than 4G of memoryKumar Gala
Previously if we >=4G of memory and !CONFIG_PHYS_64BIT we'd report an error and hang. Instead of doing that since DDR is mapped in the lowest priority LAWs we setup the DDR controller and the max amount of memory we report back is what we can map (CONFIG_MAX_MEM_MAPPED) Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Becky Bruce <beckyb@kernel.crashing.org>
2009-02-16fsl-ddr: ignore memctl_intlv_ctl setting if only one DDR controllerKumar Gala
If we only have one controller we can completely ignore how memctl_intlv_ctl is set. Otherwise other levels of code get confused and think we have twice as much memory. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-01-23fsl-ddr: use the 1T timing as default configurationDave Liu
For light loaded system, we use the 1T timing to gain better memory performance, but for some heavily loaded system, you have to add the 2T timing options to board files. Signed-off-by: Dave Liu <daveliu@freescale.com> Acked-by: Andy Fleming <afleming@freescale.com>
2009-01-23fsl-ddr: make the self refresh idle threshold configurableDave Liu
Some 85xx processors have the advanced power management feature, such as wake up ARP, that needs enable the automatic self refresh. If the DDR controller pass the SR_IT (self refresh idle threshold) idle cycles, it will automatically enter self refresh. However, anytime one transaction is issued to the DDR controller, it will reset the counter and exit self refresh state.

2008-08-27FSL DDR: Rewrite the FSL mpc8xxx DDR controller setup code.Kumar Gala
The main purpose of this rewrite it to be able to share the same initialization code on all FSL PowerPC products that have DDR controllers. (83xx, 85xx, 86xx). The code is broken up into the following steps: GET_SPD COMPUTE_DIMM_PARMS COMPUTE_COMMON_PARMS GATHER_OPTS ASSIGN_ADDRESSES COMPUTE_REGS PROGRAM_REGS This allows us to share more code an easily allow for board specific code overrides. Additionally this code base adds support for >4G of DDR and provides a foundation for supporting interleaving on processors with more than one controller.
