      USB EHCI: reset root hub · e90fb6af
      Yuri Tikhonov authored and Wolfgang Denk's avatar Wolfgang Denk committed
      
      
      Some of multi-function USB controllers (e.g. ISP1562) allow root hub
      resetting only via EHCI registers. So, this patch adds the
      corresponding kind of reset to OHCI's hc_reset() if the newly
      introduced CONFIG_PCI_EHCI_DEVNO option is set (e.g. for Socrates
      board).

      devices: Use list_add_tail() instead of list_add() to register a device · 3e3c026e
      Stefan Roese authored and Wolfgang Denk's avatar Wolfgang Denk committed
      
      
      This patch fixes a problem spotted on Glacier/Canyonlands (and most
      likely lots of other board ports), that no serial output was seen
      after console initialization in console_init_r(). This is because the
      last added console device was used instead of the first added.
      
      This patch fixes this problem by using list_add_tail() instead of
      list_add() to register a device. This way the first added console
      is used again.

      ppc4xx: IBM Memory Controller DDR autocalibration routines · 075d0b81
      Adam Graham authored and Stefan Roese's avatar Stefan Roese committed
      
      
      Alternate SDRAM DDR autocalibration routine that can be generically used
      for any PPC4xx chips that have the IBM SDRAM Controller core allowing for
      support of more DIMM/memory chip vendors and gets the DDR autocalibration
      values which give the best read latency performance (SDRAM0_RDCC.[RDSS]).
      
      Two alternate SDRAM DDR autocalibration algoritm are provided in this patch,
      "Method_A" and "Method_B".  DDR autocalibration Method_A scans the full range
      of possible PPC4xx  SDRAM Controller DDR autocalibration values and takes a
      lot longer to run than Method_B.  Method_B executes in the same amount of time
      as the currently existing DDR autocalibration routine, i.e. 1 second or so.
      Normally Method_B is used and it is set as the default method.
      
      The current U-Boot PPC4xx DDR autocalibration code calibrates the IBM SDRAM
      Controller registers.[bit-field]:
      1)  SDRAM0_RQDC.[RQFD]
      2)  SDRAM0_RFDC.[RFFD]
      
      This alternate PPC4xx DDR autocalibration code calibrates the following
      IBM SDRAM Controller registers.[bit-field]:
      
      1)  SDRAM0_WRDTR.[WDTR]
      2)  SDRAM0_CLKTR.[CKTR]
      3)  SDRAM0_RQDC.[RQFD]
      4)  SDRAM0_RFDC.[RFFD]
      
      and will also use the calibrated settings of the above four registers that
      produce the best "Read Sample Cycle Select" value in the SDRAM0_RDCC.[RDSS]
      register.[bit-field].

      ppc44x: Unification of virtex5 pp440 boards · e07f4a80
      Ricardo Ribalda Delgado authored and Stefan Roese's avatar Stefan Roese committed
      
      
      This patch provides an unificated way of handling xilinx v5 ppc440 boards.
      
      It unificates 3 different things:
      
      1) Source code
      A new board called ppc440-generic has been created. This board includes
      a generic tlb initialization (Maps the whole memory into virtual) and
      defines board_pre_init, checkboard, initdram and get_sys_info weakly,
      so, they can be replaced by specific functions.
      
      If a new board needs to redefine any of the previous functions
      (specific initialization) it can create a new directory with the
      specific initializations needed. (see the example ml507 board).
      
      2) Configuration file
      Common configurations are located under configs/xilinx-ppc440.h, this
      header file interpretes the xparameters file generated by EDK and
      configurates u-boot in correspondence. Example: if there is a Temac,
      allows CMD_CONFIG_NET
      Specific configuration are located under specific configuration file.
      (see the example ml507 board)
      
      3) Makefile
      Some work has been done in order to not duplicate work in the Main
      Makefile. Please see the attached code.
      
      In order to support new boards they can be implemented in the next way:
      
      a) Simple Generic Board  (90% of the time)
      Using EDK generates a new xparameters.h file, replace
      ppc440-generic/xparameters.h  and run make xilinx-ppc440-generic_config
      && make
      
      b) Simple Boards with special u-boot parameters (9 % of the time)
      Create a new file under configs for it (use ml507.h as example) and
      change your paramaters. Create a new Makefile paragraph and compile
      
      c) Complex boards (1% of the time)
      Create a new folder for the board, like the ml507
      
      Finally, it adds support for the Avnet FX30T Evaluation board, following
      the new generic structure:
      
      Cheap board by Avnet for evaluating the Virtex5 FX technology.
      
      This patch adds support for:
       - UartLite
       - 16MB Flash
       - 64MB RAM
      
      Prior using U-boot in this board, read carefully the ERRATA by Avnet
      to solve some memory initialization issues.
