Stefan Roese 58eb869ffc ppc4xx: Add "ecctest" command to test/simulate ECC errors ... This patch adds the "ecctest" command to test and simulate ECC errors (single bit and/or double bit) while running from SDRAM. Currently only the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT). This is done by copying and calling functions, modifying the SDRAM controller operation mode, in internal SRAM/OCM. For correctable ECC errors (single bit) only the status will be printed since the DDR2 controller doesn't provide the faulting address: => ecctest 1000000 1 Using address 01000000 for 1 bit ECC error injection ECC: Correctable error Uncorrectable ECC errors (double bit) will also display the faulting address: => ecctest 1000000 2 Using address 01000000 for 2 bit ECC error injection ECC: Uncorrectable error at 0x0001000000 To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST in the board config header. Tested on katmai and t3corp. Signed-off-by: Stefan Roese <sr@denx.de>		2010-07-23 09:54:54 +02:00
