* powerpc/mpc83xx: Migrate from spd_sdram to unified DDR driverYork Sun2011-09-29-19/+245
| | | | | | | | | | | | | | | | | 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: Refactor P2041RDB to use common p_corenet filesKumar Gala2011-09-29-202/+13
| | | | | | | | | | | The P2041RDB has almost identical setup for TLB, LAWS, and PCI with other P-Series CoreNet platforms. The only difference between P2041RDB & P3041DS/P4080DS/P5020DS is the CPLD vs PIXIS FPGA which we can handle via some simple #ifdefs in the TLB and LAW setup tables.

* powerpc/hydra: Add ethernet support on P5020/P3041 DS boardsTimur Tabi2011-09-29-0/+555
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P3041DS & P5020DS ("Hydra"). The lane_to_slot[] array is initialized dynamically, since board switches can be used to control the muxing of SERDES lanes to slots. The BRDCFG1 PIXIS register is used to route the MII bus to the appropriate slot. The SERDES configuration is queried to help determine the routing between MACs and slot/phy combination. If a XAUI card is inserted, muxing for that card is enabled and never turned off. The PHY address for the 10G XAUI card depends on the slot in which it's inserted. If it's in slot 1, the address is 4. If it's in slot 2, the address is 0. Update the MDIO routing in the P3041DS and P5020DS device trees based on the board-level muxing. The SERDES configuration determines which SGMII/XGMII boards are located in which slots, and so the MDIO bus needs to be muxed correctly whenever talking to a PHY connected to any Fman MAC. The Fman Ethernet nodes in the device tree also need to be routed to the correct PHYs. Removed CONFIG_SYS_FMAN_FW as its not used anywhere.

| | | | | | | | | | | | | | | | | | | | | | | Add support for RGMII, SGMII, and XAUI (10Gb) Ethernet on P4080DS. The board supports add-on cards for SGMII and XAUI functionality. Which slots on the board these cards are in is a function of the SERDES option selected and muxes on the board. Additionally because of the high-configurablity which MDIO bus one is connected to is "selected" via an FPGA register. We create dummy MDIO bus for the phy layer and hide the mux manipulation in this dummy layer. Add fman fdt helper function in board common code it'll be used by several freescale boards that do various muxing of the MDIO signals based on which controller/interface one is trying to talk to.

* powerpc/85xx: Add support for FMan ethernet in Independent modeKumar Gala2011-09-29-12/+3068
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

P2020RDB-PC differs from the P102x RDB-PC with 64-bit DDR and 100Mhz SYSCLK. Key features on these boards include: * DDR3 * NOR flash * NAND flash (on RDB's only) * SPI flash (on RDB's only) * SDHC/MMC card slot * VSC7385 Ethernet switch (on P1020MBG, P1020RDB, & P1021RDB) * PCIE slot and mini-PCIE slots As these boards use soldered DDR chips not regular DIMMs, an on-board EEPROM is used to store SPD data. In case of absent or corrupted SPD, falling back to timing data embedded in the source code will be used. Raw timing data is extracted from DDR chip datasheet. Different speeds of DDR are supported with this approach. ODT option is forced to fit this set of boards, again because they don't have regular DIMMs. CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS is defined as 5ms to meet specification for writing timing. VSC firmware Address is defined by default in config file for eTSEC1. SD width is based off DIP switch. DIP switch is detected on the board by reading i2c bus and setting the appropriate mux values. Some boards have QE module in the silicon (P1021 and P1025). QE and eLBC have pins multiplexing. QE function needs to be disabled to access Nor Flash and CPLD. QE-UEC and QE-UART can be enabled for linux kernel by setting "qe" in hwconfig. In addition, QE-UEC and QE-TDM also have pins multiplexing, to enable QE-TDM for linux kernel, set "qe;tdm" in hwconfig. Syntax is as below 'setenv hwconfig qe' to enable QE UEC/UART and disable Nor-Flash/CPLD. 'setenv hwconfig 'qe;tdm'' to enalbe QE TDM and disable Nor-Flash/CPLD.

* powerpc/85xx: relocate CCSR before creating the initial RAM areaTimur Tabi2011-09-29-58/+234
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before main memory (DDR) is initialized, the on-chip L1 cache is used as a memory area for the stack and the global data (gd_t) structure. This is called the initial RAM area, or initram. The L1 cache is locked and the TLBs point to a non-existent address (so that there's no chance it will overlap main memory or any device). The L1 cache is also configured not to write out to memory or the L2 cache, so everything stays in the L1 cache. One of the things we might do while running out of initram is relocate CCSR. On reset, CCSR is typically located at some high 32-bit address, like 0xfe000000, and this may not be the best place for CCSR. For example, on 36-bit systems, CCSR is relocated to 0xffe000000, near the top of 36-bit memory space. On some future Freescale SOCs, the L1 cache will be forced to write to the backing store, so we can no longer have the TLBs point to non-existent address. Instead, we will point the TLBs to an unused area in CCSR. In order for this technique to work, CCSR needs to be relocated before the initram memory is enabled. Unlike the original CCSR relocation code in cpu_init_early_f(), the TLBs we create now for relocating CCSR are deleted after the relocation is finished. cpu_init_early_f() will still need to create a TLB for CCSR (at the new location) for normal U-Boot purposes. This is done to keep the impact to existing U-Boot code minimal and to better isolate the CCSR relocation code.

* powerpc/85xx: introduce and document CONFIG_SYS_CCSRBAR macrosTimur Tabi2011-09-29-277/+170
| | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, which contain the high and low portions of CONFIG_SYS_CCSRBAR_PHYS. This is necessary for the assembly-language code that relocates CCSR, since the assembler does not understand 64-bit constants. CONFIG_SYS_CCSRBAR_PHYS is automatically defined from the CONFIG_SYS_CCSRBAR_PHYS_HIGH and CONFIG_SYS_CCSRBAR_PHYS_LOW macros, so it should not be defined in a board header file. Similarly, CONFIG_SYS_CCSRBAR_DEFAULT is defined for each SOC in config_mpc85xx.h, so it should also not be defined in the board header file. CONFIG_SYS_CCSR_DO_NOT_RELOCATE is a "short-cut" macro that guarantees that CONFIG_SYS_CCSRBAR_PHYS is set to the same value as CONFIG_SYS_CCSRBAR_DEFAULT, and so CCSR will not be relocated. Since CONFIG_SYS_CCSRBAR_DEFAULT is locked to a fixed value, multi-stage U-Boot builds (e.g. NAND) are required to relocate CCSR only during the last stage (i.e. the "real" U-Boot). All other stages should define CONFIG_SYS_CCSR_DO_NOT_RELOCATE to ensure that CCSR is not relocated. README is updated with descriptions of all the CONFIG_SYS_CCSRBAR_xxx macros.

* Revert "phylib: remove a couple of redundant code lines"Wolfgang Denk2011-09-28-2/+5
| | | | | | | | | | | | | | | | | | | | | | This reverts commit 041c542219af7f31c372d89b4c7c6f4c8064a8ce. The lines removed by this commit weren't redundant. The logic is (and probably should be better commented): Find the intersection of the advertised capabilities of both sides of the link (lpa). From that intersection, find the highest capability we can run at (that will be the negotiated link). Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL). The code will now set phydev->speed to 100, and phydev->duplex to 1, but this link does not support 100FULL. Kudos to Andy Fleming <afleming@gmail.com> for binging this to attention and for the explanation. Signed-off-by: Wolfgang Denk <wd@denx.de>
