Notes

Toolchain

  • The Ubuntu 12.04.2 LTS version of the arm-linux-gnueabi toolchain is broken for this target. A U-Boot image will successfully compile but will not boot. The LaCie GPL U-Boot source will not compile at all (processor Thumb support error).
  • The Ubuntu 13.04 version of the same toolchain works.

Functional Specs

CPU Address Decoding

Sheeva CPU core has 13 address windows:

  • 4x for CPU access to DRAM CS
  • 1x for CPU access to internal registers
  • 8x configurable for CPU access to remaining chip resources
DRAM Windows
  • 8-bit BASE & SIZE registers
  • BASE corresponds to address bits [31:24]
  • Min. SIZE (0x01) = 16MB; max. SIZE (0xFF) = 4GB
  • SIZE is a mask; only 8 legal values (0x01, 0x03, 0x07, 0x0F, etc.)
Register Window
  • Fixed SIZE of 1MB
  • BASE register
Configurable Windows
  • 16-bit BASE & SIZE registers
  • BASE corresponds to address bits [31:16]
  • Min. SIZE (0x0001) = 64KB; max. SIZE (0xFFFF) = 4GB
  • SIZE is a mask; 16 legal values

SATA Address Decoding

  • 4x address windows
  • SDRAM and PCIe interface access

GbE Address Decoding

  • 6x address windows
  • SDRAM interface access only

USB Address Decoding

  • 4x address windows per USB port
  • SDRAM interface access only

SDIO Address Decoding

  • 4x programmable address windows
  • SDRAM and PCIe interface access

Wish I found this earlier (kirkwood/cpu.c): Linux expects the internal registers to be at 0xF1000000

Internal registers base address is set in register offset 0x20080 (arch-kirkwood/kirkwood.h): i.e. 0xF1020080 = 0xF1000000
