  "message": "ppc4xx: Add \"ecctest\" command to test/simulate ECC errors\n\nThis patch adds the \"ecctest\" command to test and simulate ECC errors\n(single bit and/or double bit) while running from SDRAM. Currently only\nthe IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).\n\nThis is done by copying and calling functions, modifying the SDRAM\ncontroller operation mode, in internal SRAM/OCM.\n\nFor correctable ECC errors (single bit) only the status will be printed\nsince the DDR2 controller doesn\u0027t provide the faulting address:\n\n\u003d\u003e ecctest 1000000 1\nUsing address 01000000 for 1 bit ECC error injection\nECC: Correctable error\n\nUncorrectable ECC errors (double bit) will also display the faulting\naddress:\n\n\u003d\u003e ecctest 1000000 2\nUsing address 01000000 for 2 bit ECC error injection\nECC: Uncorrectable error at 0x0001000000\n\nTo enable this \"ecctest\" function you need to define CONFIG_CMD_ECCTEST\nin the board config header.\n\nTested on katmai and t3corp.\n\nSigned-off-by: Stefan Roese \u003csr@denx.de\u003e\n",
