      General help message cleanup · a89c33db
      Wolfgang Denk authored
      
      
      Many of the help messages were not really helpful; for example, many
      commands that take no arguments would not print a correct synopsis
      line, but "No additional help available." which is not exactly wrong,
      but not helpful either.
      
      Commit ``Make "usage" messages more helpful.'' changed this
      partially. But it also became clear that lots of "Usage" and "Help"
      messages (fields "usage" and "help" in struct cmd_tbl_s respective)
      were actually redundant.
      
      This patch cleans this up - for example:
      
      Before:
      	=> help dtt
      	dtt - Digital Thermometer and Thermostat
      
      	Usage:
      	dtt         - Read temperature from digital thermometer and thermostat.
      
      After:
      	=> help dtt
      	dtt - Read temperature from Digital Thermometer and Thermostat
      
      	Usage:
      	dtt

      ppc4xx: Fix bug in I2C bootstrap values for Sequoia/Rainier · e2e93442
      Stefan Roese authored
      
      
      The I2C bootstrap values that can be setup via the "bootstrap" command,
      were setup incorrect regarding the generation of the internal sync PCI
      clock. The values for PLB clock == 133MHz were slighly incorrect and the
      values for PLB clock == 166MHz were totally incorrect. This could
      lead to a hangup upon booting while PCI configuration scan.
      
      This patch fixes this issue and configures valid PCI divisor values
      for the sync PCI clock, with respect to the provided external async
      PCI frequency.
      
      Here the values of the formula in the chapter 14.2 "PCI clocking"
      from the 440EPx users manual:
      
      AsyncPCICLK - 1MHz <= SyncPCIClk <= (2 * AsyncPCIClk) - 1MHz
      
      33MHz async PCI frequency:
      PLB = 133:
      =>      32 <= 44.3 <= 65        (div = 3)
      
      PLB = 166:
      =>      32 <= 55.3 <= 65        (div = 3)
      
      66MHz async PCI frequency:
      PLB = 133:
      =>      65 <= 66.5 <= 132       (div = 2)
      
      PLB = 166:
      =>      65 <= 83 <= 132         (div = 2)

      ppc4xx: Add NAND booting support for AMCC Acadia (405EZ) eval board · c440bfe6
      Stefan Roese authored
      
      
      This patch adds NAND booting support for the AMCC Acadia eval board.
      
      Please make sure to configure jumper J7 to position 2-3 when booting
      from NOR, and to position 1-2 when booting for NAND.
      
      I also added a board command to configure the I2C bootstrap EEPROM
      values. Right now only 267MHz is support for booting either via NOR
      or NAND FLASH. Here the usage:
      
      => bootstrap 267 nor	;to configure the board for 267MHz NOR booting
      => bootstrap 267 nand	;to configure the board for 267MHz NNAND booting
