ppc4xx: Sequoia: Add chip_config command

2009-10-23T14:05:11Z

This patch removes the Sequoia "bootstrap" command and replaces it with the now common command "chip_config". Please note that the patches with the dynamic PCI sync clock configuration have to be applied, before this one should go in. This is because Sequoia has 2 different bootstrap EEPROMs, and the old bootstrap command configured different values depending on the detected PCI async clock (33 vs. 66MHz). With the PCI sync clock patches, this is not necessary anymore. The PCI sync clock will be configured correctly on-the-fly now. Signed-off-by: Stefan Roese

General help message cleanup

2009-06-12T18:47:16Z

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 Signed-off-by: Wolfgang Denk

Command usage cleanup

2009-01-28T07:49:52Z

Remove command name from all command "usage" fields and update common/command.c to display "name - usage" instead of just "usage". Also remove newlines from command usage fields. Signed-off-by: Peter Tyser

ppc4xx: Fix bug in I2C bootstrap values for Sequoia/Rainier

2007-10-15T09:39:00Z

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) Signed-off-by: Stefan Roese

ppc4xx: Add bootstrap command for AMCC Sequoia (440EPx) eval board

2007-06-19T15:22:44Z

This patch adds a board command to configure the I2C bootstrap EEPROM values. Right now 533 and 667MHz are supported for booting either via NOR or NAND FLASH. Here the usage: => bootstrap 533 nor ;to configure the board for 533MHz NOR booting => bootstrap 667 nand ;to configure the board for 667MHz NNAND booting Signed-off-by: Stefan Roese
