Use the return value of cmd_usage instead of ignoring this and returning a 1. Signed-off-by: Thomas Weber <weber@corscience.de> Acked-by: Mike Frysinger <vapier@gentoo.org>
2010-09-23ppc4xx: Move ppc4xx headers to powerpc include directoryStefan Roese
This patch moves some ppc4xx related headers from the common include directory (include/) to the powerpc specific one (arch/powerpc/include/asm/). This way to common include directory is not so cluttered with files. Signed-off-by: Stefan Roese <sr@denx.de>
2010-07-23ppc4xx: Add "ecctest" command to test/simulate ECC errorsStefan Roese
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>
