  15. - make DK1C20 board configuration related to ASMI conform to
  16. documentation
  17. * Patch by Anders Larsen, 09 Jan 2004:
  18. ARM memory layout fixes: the abort-stack is now set up in the
  19. correct RAM area, and the BSS is zeroed out as it should be.
  20. Furthermore, the magic variables 'armboot_end' and 'armboot_end_data'
  21. of the linker scripts are replaced by '__bss_start' and '_end',
  22. resp., which is a further step to eliminate unnecessary differences
  23. between the implementation of the CPU architectures.
  24. * Patch by liang a lei, 9 Jan 2004:
  25. Fix Intel 28F128J3 ID in include/flash.h
  26. * Patch by Masami Komiya, 09 Jan 2004:

  33. select MDI port based on enabled EMAC device.
  34. Add support for XES Inc <http://www.xes-inc.com> XPedite1000 440GX
  35. base PrPMC board.
  36. * Patch by Wolter Kamphuis, 15 Dec 2003:
  37. made CONFIG_SILENT_CONSOLE usable on all architectures
  38. * Disable date command on TQM866M - there is no RTC on MPC866
  39. * Fix variable CPU clock for MPC859/866 systems for low CPU clocks
  40. * Implement adaptive SDRAM timing configuration based on actual CPU
  41. clock frequency for INCA-IP; fix problem with board hanging when
  42. switching from 150MHz to 100MHz
  43. * Add PCMCIA CS support for BMS2003 board
  44. * Add variable CPU clock for MPC859/866 systems (so far only TQM866M):
  45. see doc/README.MPC866 for details;
  46. implement workaround for "SIU4" and "SIU9" silicon bugs on MPC866;
  47. calculate CPU clock frequency from PLL register values.
  48. * Add support for 128 MB RAM on TQM8xxL/M modules
  49. * Fix PS/2 keyboard problem caused by statically initialized variable
  50. pointing to a location in flash
  51. * Fix INCA-IP clock calculation: 400/3 = 133.3 MHz, not 130.
  52. * The PS/2 mux on the BMS2003 board needs 450 ms after power on
  53. before we can access it; add delay in case we are faster (with no
  54. CF card inserted)
  55. * Cleanup of some init functions
  56. * Make sure SCC Ethernet is always stopped by the time we boot Linux
  57. to avoid Linux crashes by early packets coming in.
  58. * Accelerate flash accesses on LWMON board by using buffered writes
  59. * Fix typo in Makefile;
  60. fix problem with PARTNUM detection
  61. * Patch by Reinhard Meyer, 09 Jan 2004:
  62. - add RTC support for MPC5200 based boards (requires RTC_XTAL)
  63. * Add support for IDE LED on BMS2003 board
  64. (exclusive with status LED!)
  65. * Add support for PS/2 keyboard (used with PS/2 multiplexor on
  66. BMS2003 board)
  67. * Patches by Reinhard Meyer, 4 Jan 2004 + 7 Jan 2004:
  68. Add common files for "emk" boards
  69. * Add a common get_ram_size() function and modify the the
  70. board-specific files to invoke that common implementation.
