| | | | | | | | | | | Update device tree handling for SRIO controller to support updated fsl,srio device tree binding. We handle disabling of individual ports, the whole controller, RMU, and RMAN.

* powerpc/85xx: Update setting of SRIO LIODNsKumar Gala2011-10-18-6/+50
| | | | | | | | | | | Properly set the LIODN values associated with SRIO controller. On P4080/P3060 we have an LIODN per port and one for the RMU. On P2041/P3041/P5020 we have 2 LIODNs per port. Update the tables for all of these devices to properly handle both styles. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

| | | | | | | | | | | | | | | | | | | | | | | | Function fdt_create_phandle() conveniently creates new phandle properties using both "linux,phandle" and "phandle", so it should be used by all code that wants to create a phandle. The Fman firmware code, which embeds an Fman firmware into the device tree, was creating the phandle properties manually. Instead, change it to use fdt_create_phandle().

* powerpc/mpc86xx: Disable translation for BAT setupBecky Bruce2011-10-09-29/+68
| | | | | | | | | | | | | | | | | We really shouldn't be overwriting bat registers with translation enabled, especially when we're executing code using one of them for translating the current instruction stream. Instead, disable address translation while doing the final BAT setup. In order to do this, setup_bats has to move back to asm code, because we require translation to be enabled to have a stack for C code. The yucky thing about that is that the assembler doesn't like ULL so we have to switch to using HIGH/LOW pairs for physical addresses that are > 32 bits in length.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| * nand: Freescale Integrated Flash Controller NAND supportDipen Dudhat2011-09-29-3/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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>
* 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>

* powerpc/85xx: verify the device tree before booting LinuxTimur Tabi2011-07-29-0/+72
| | | | | | | | | | | | | | | Introduce ft_verify_fdt(), a function that is called after the device tree has been fixed up, that displays warning messages if there is a mismatch between the physical addresses of some devices that U-Boot has configured with what the device tree says the addresses are. 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. When the operating system boots, no messages are displayed, so the user generally has no idea what's wrong.
