* powerpc/8xxx: Add support for interactive DDR programming interfaceYork Sun2011-10-09-17/+1726
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interactive DDR debugging provides a user interface to view and modify SPD, DIMM parameters, board options and DDR controller registers before DDR is initialized. With this feature, developers can fine-tune DDR for board bringup and other debugging without frequently having to reprogram the flash. To enable this feature, define CONFIG_FSL_DDR_INTERACTIVE in board header file and set an environment variable to activate it. Syntax: setenv ddr_interactive on After reset, U-boot prompts before initializing DDR controllers FSL DDR> The available commands are print print SPD and intermediate computed data reset reboot machine recompute reload SPD and options to default and recompute regs edit modify spd, parameter, or option compute recompute registers from current next_step to end next_step shows current next_step help this message go program the memory controller and continue with u-boot The first command should be "compute", which reads data from DIMM SPDs and board options, performs the calculation then stops before setting DDR controller. A user can use "print" and "edit" commands to view and modify anything. "Go" picks up from current step with any modification and compltes the calculation then enables the DDR controller to continue u-boot. "Recompute" does it over from fresh reading.

* powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun2011-09-29-4/+9
| | | | | | | | | | | | | | | | | Unified DDR driver is maintained for better performance, robustness and bug fixes. Upgrading to use unified DDR driver for MPC83xx takes advantage of overall improvement. It requires changes for board files to customize platform-dependent parameters. To utilize the unified DDR driver, a board needs to define CONFIG_FSL_DDRx in the header file. No more boards will be accepted without such definition. Note: the workaround for erratum DDR6 for the very old MPC834x Rev 1.0/1.1 and MPC8360 Rev 1.1/1.2 parts is not migrated to unified driver.

* powerpc/85xx: Add support for FMan ethernet in Independent modeKumar Gala2011-09-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Frame Manager (FMan) on QorIQ SoCs with DPAA (datapath acceleration architecture) is the ethernet contoller block. Normally it is utilized via Queue Manager (Qman) and Buffer Manager (Bman). However for boot usage the FMan supports a mode similar to QE or CPM ethernet collers called Independent mode. Additionally the FMan block supports multiple 1g and 10g interfaces as a single entity in the system rather than each controller being managed uniquely. This means we have to initialize all of Fman regardless of the number of interfaces we utilize. Different SoCs support different combinations of the number of FMan as well as the number of 1g & 10g interfaces support per Fman. We add support for the following SoCs: * P1023 - 1 Fman, 2x1g * P4080 - 2 Fman, each Fman has 4x1g and 1x10g * P204x/P3041/P5020 - 1 Fman, 5x1g, 1x10g Signed-off-by: Dave Liu <daveliu@freescale.com> Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Signed-off-by: Dai Haruki <dai.haruki@freescale.com> Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Ioana Radulescu <ruxandra.radulescu@freescale.com> Signed-off-by: Lei Xu <B33228@freescale.com> Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Shaohui Xie <b21989@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* fsl_ifc: Add the workaround for erratum IFC A-003399(enabled on P1010)Poonam Aggrwal2011-09-29-0/+2
| | | | | | | | | | | | | | | | | | Issue: Address masking doesn't work properly. When sum of the base address, defined by BA, and memory bank size, defined by AM, exceeds 4GB (0xffff_ffff) then AMASKn[AM] doesn't mask CSPRn[BA] bits. Impact: This will impact booting when we are reprogramming CSPR0(BA) and AMASK0(AMASK) while executing from NOR Flash. Workaround: Re-programming of CSPR(BA) and AMASK is done while not executing from NOR Flash. The code which programs the BA and AMASK is executed from L2-SRAM.

* powerpc/8xxx: Remove dependency on <usb.h>Kumar Gala2011-07-29-4/+3
| | | | | | | | | | | | | | | We used <usb.h> for USB_MAX_DEVICE. However this requires we actual build in support for USB into u-boot (which should not be required for device tree fixup). At this time no FSL SoC that utilizies this code (83xx/85xx) has more than 2 USB controllers. So we replace USB_MAX_DEVICE with a local define FSL_MAX_NUM_USB_CTRLS. If/when a device shows up with more than 2 controllers we can easily bump this value or refactor into a proper define per SoC. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* fsl_ddr: Don't use full 64-bit divides on 32-bit PowerPCKyle Moffett2011-04-04-16/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current FreeScale MPC-8xxx DDR SPD interpreter is using full 64-bit integer divide operations to convert between nanoseconds and DDR clock cycles given arbitrary DDR clock frequencies. Since all of the inputs to this are 32-bit (nanoseconds, clock cycles, and DDR frequencies), we can easily restructure the computation to use the "do_div()" function to perform 64-bit/32-bit divide operations. On 64-bit this change is basically a no-op, because do_div is implemented as a literal 64-bit divide operation and the instruction scheduling works out almost the same. On 32-bit PowerPC a fully accurate 64/64 divide (__udivdi3 in libgcc) is over 1.1kB of code and thousands of heavily dependent cycles to compute, all of which is linked from libgcc. Another 1.2kB of code comes in for the function __umoddi3. It should be noted that nothing else in U-Boot or the Linux kernel seems to require a full 64-bit divide on my 32-bit PowerPC. Build-and-boot-tested on the HWW-1U-1A board using DDR2 SPD detection.

* mpc8xxx: Enable ECC on/off control in hwconfigYork Sun2011-01-19-3/+6
| | | | | | | | | | | | | | Add fsl_ddr:ecc=on in hwconfig. If ECC is enabled in board configuration file, ECC can be turned on/off by this switch. If this switch is omitted, it is ON by default. Updated hwconfig calls to use local buffer. Syntax is hwconfig=fsl_ddr:ecc=on Signed-off-by: York Sun <yorksun@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* powerpc/8xxx: Add hwconfig APIs to address early parsing used by DDR initKumar Gala2011-01-19-19/+59
| | | | | | | | | | | | | | | | | | | | | | | | | There are several users of the hwconfig APIs (8xxx DDR) before we have the environment properly setup. This causes issues because of the numerous ways the environment might be accessed because of the non-volatile memory it might be stored in. Additionally the access might be so early that memory isn't even properly setup for us. Towards resolving these issues we provide versions of all the hwconfig APIs that can be passed in a buffer to parse and leave it to the caller to determine how to allocate and populate the buffer. We use the _f naming convention for these new APIs even though they are perfectly useable after relocation and the environment being ready. We also now warn if the non-f APIs are called before the environment is ready to allow users to address the issues. Finally, we convert the 8xxx DDR code to utilize the new APIs to hopefully address the issue once and for all. We have the 8xxx DDR code create a buffer on the stack and populate it via getenv_f().
