* powerpc/85xx: CONFIG_ENABLE_36BIT_PHYS does not depend on CONFIG_PHYS_64BITTimur Tabi2011-10-09-2/+1
| | | | | | | | | | The macro CONFIG_ENABLE_36BIT_PHYS is used to indicate that the given SOC is capable of 36-bit physical addresses, even if such large addresses are not used. On two boards, this macro was enabled only when building a 36-bit image. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc/8xxx: Add support for interactive DDR programming interfaceYork Sun2011-10-09-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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/85xx: Add support for new P102x/P2020 RDB style boardsLi Yang2011-09-29-0/+984
The following boards share a common design but with minor variations between them: P1020MSBG-PC P1020RDB-PC P1020UTM-PC P1021RDB-PC P1024RDB P1025RDB P2020RDB-PC The P1020RDB-PC shares its roots in the existing P1020RDB board design, however uses DDR3 instead of DDR2. 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.
