* powerpc/85xx: Add support for FMan ethernet in Independent modeKumar Gala2011-09-29-12/+741
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/+95
| | | | | | | | | | | | | | | | | | 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/85xx: Expanding the window of CCSRBAR in AS=1 from 4k to 1MPoonam Aggrwal2011-09-29-3/+4
| | | | | | | | | | | For an IFC Erratum (A-003399) we will need to access IFC registers in cpu_init_early_f() so expand the TLB covering CCSR to 1M.

* nand: Freescale Integrated Flash Controller NAND supportDipen Dudhat2011-09-29-7/+27
| | | | | | | | | | | | | | | Add NAND support (including spl) on IFC, such as is found on the p1010. Note that using hardware ECC on IFC with small-page NAND (which is what comes on the p1010rdb reference board) means there will be insufficient OOB space for JFFS2, since IFC does not support 1-bit ECC. UBI should work, as it does not use OOB for anything but ECC. When hardware ECC is not enabled in CSOR, software ECC is now used.

* 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 Tabi2011-09-29-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* video: Add SHARP LQ084S3LG01 LCD support on P1022DSTimur Tabi2011-08-04-1/+1
| | | | | | | | | | | | | | | | | The SHARP LQ084S3LG01 is a TFT LCD used on the P1022DS (revision "C") board. This device only supports 800x600 resolution, so if that resolution is selected, assume that this is the device. The device is attached to the LVDS port on the P1022DS board. The existing 800x600 entry (for the PDM360NG board) is actually 800x480, so we fix that. To support two different 800x resolutions, the Y-resolution is now passed to fsl_diu_init() and both values are used to pick the proper fb_videomode structure. The data for the 800x600 video mode is originally from Jiang Yutang. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Jiang Yutang <b14898@freescale.com>

| | | | | | | | | | | | | | | 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>

This is a particular problem when booting a 36-bit device tree from a 32-bit U-Boot (or vice versa), because the physical address of CCSR is wrong in the device tree.

* fman: insert the Fman firmware into the device treeTimur Tabi2011-07-22-0/+123
| | | | | | | | | | | | The Fman device tree node binding allows for the entire Fman firmware binary data to be embedded in the device tree. This eliminates the need to have NOR flash mapped to Linux just so that the Fman driver can see the firmware. The location of the Fman firmware is taken from the 'fman_ucode' environment variable.

* powerpc/85xx: add support the ePAPR "phandle" propertyTimur Tabi2011-07-22-2/+4
| | | | | | | | | | | The ePAPR specification says that phandle properties should be called "phandle", and not "linux,phandle". To facilitate the migration from "linux,phandle" to "phandle", we update fdt_qportal() to use the new function, fdt_create_phandle(). This function abstracts the creation of phandle properties.

* powerpc/85xx: remove SERDES4 soft-reset work-aroundTimur Tabi2011-07-11-22/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some P4080 rev1 errata work-arounds, notably erratum SERDES4, required a bank soft-reset after the bank was configured and enabled, even though enabling a bank causes it to reset. Because the reset was required for multiple errata, it was not properly enclosed in an #ifdef, and so was not removed with all the other rev1 errata work-arounds. Erratum SERDES-8 says that the clocks for bank 3 needs to be enabled if bank 2 is enabled, but this was not being done for SERDES protocols 0xF and 0x10. The bank reset also happened to enable bank 3 (apparently an undocumented feature). Simply removing the reset breaks these two protocols. It turns out that every time we call enable_bank(), we do want at least one lane of the bank enabled, either because the bank is supposed to be enabled, or because we need the clock from that bank enabled. For erratum SERDES-A001, we don't want to modify srds_lpd_b[] when we call enable_bank(), because that array is used elsewhere to determine if the bank is available. Note that the side effect of these changes is that the work-arounds for these two errata are now linked. Specifically, if SERDES-A001 is enabled, then we need SERDES-8 enabled as well. Because this was the only SERDES bank soft-reset, there is no need to implement a work-around for erratum SERDES-A003. Also fix an off-by-one error in a printf().
