  5. config SET_MEM_PARAM
  6. bool "Set flash/sdram size and base addr"
  7. help
  8. Say Y to manually set the base addresses and sizes.
  9. otherwise, the default values are assigned.
  10. config DRAM_BASE
  11. hex '(S)DRAM Base Address' if SET_MEM_PARAM
  12. default 0x00800000
  13. config DRAM_SIZE
  14. hex '(S)DRAM SIZE' if SET_MEM_PARAM
  15. default 0x00800000
  16. config FLASH_MEM_BASE
  17. hex 'FLASH Base Address' if SET_MEM_PARAM

  23. hex

  25. depends on !CPU_CP15
  26. help
  27. If processor has no CP15 register, this processor ID is
  28. used instead of the auto-probing which utilizes the register.
  29. config REMAP_VECTORS_TO_RAM
  30. bool 'Install vectors to the begining of RAM' if DRAM_BASE
  31. depends on DRAM_BASE
  32. help
  33. The kernel needs to change the hardware exception vectors.
  34. In nommu mode, the hardware exception vectors are normally
  35. placed at address 0x00000000. However, this region may be
  36. occupied by read-only memory depending on H/W design.
  37. If the region contains read-write memory, say 'n' here.
  38. If your CPU provides a remap facility which allows the exception
  39. vectors to be mapped to writable memory, say 'n' here.
  40. Otherwise, say 'y' here. In this case, the kernel will require
  41. external support to redirect the hardware exception vectors to
  42. the writable versions located at DRAM_BASE.
