* powerpc/p1_p2_rdb_pc: Add a pin to reset the DDR chip for P1021RDB-PCXu Jiucheng2013-05-021-1/+18
| | | | | | | | | | | | | | | When P1021RDB-PC reboot system, the board will hung at uboot DDR configuration. For P1021RDB-PC DDR reset pin is multiplex with QE, so uboot will reserve this pin for QE and skip DDR reset. Other platforms without QE will do this reset. This patch adds a slight code to reset DDR chip by QE CE_PB8 pin for NAND and NOR FLASH boot. For booting from SPI FALSH and SD card, it seems possible to use the rom on chip to write to the GPIO pins before configuring the DDR.

* powerpc/85xx: don't display address map size (32-bit vs. 36-bit) during bootTimur Tabi2012-04-241-7/+1
| | | | | | | | | | | | | | | | Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes displays which of these is actually built, but it's inconsistent. This is especially problematic since the "default" build for a given 85xx board can be either one, so if you don't see a message, you can't always know which size is being used. Not only that, but each board includes code that displays the message, so there is duplication. The 'bdinfo' command has been updated to display this information, so we don't need to display it at boot time. The board-specific code is deleted.

* powerpc/85xx: Add support for new P102x/P2020 RDB style boardsLi Yang2011-09-291-0/+449
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.
