2018-11-20EDAC, fsl: Move error injection under CONFIG_EDAC_DEBUGYork Sun1-0/+4
Gate error injection feature with CONFIG_EDAC_DEBUG so that it is not visible in production setups.

2017-02-09EDAC, fsl_ddr: Make locally used symbols staticWei Yongjun1-6/+6
Fix the following sparse warnings: drivers/edac/fsl_ddr_edac.c:148:1: warning: symbol 'dev_attr_inject_data_hi' was not declared. Should it be static? drivers/edac/fsl_ddr_edac.c:150:1: warning: symbol 'dev_attr_inject_data_lo' was not declared. Should it be static? drivers/edac/fsl_ddr_edac.c:152:1: warning: symbol 'dev_attr_inject_ctrl' was not declared. Should it be static?

2016-12-15edac: rename edac_core.h to edac_mc.hMauro Carvalho Chehab1-1/+0
Now, all left at edac_core.h are at drivers/edac/edac_mc.c, so rename it to edac_mc.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-09-09EDAC, fsl_ddr: Fix error return code in fsl_mc_err_probe()Wei Yongjun1-1/+2
Return negative error code from the edac_mc_add_mc() error handling case instead of 0, as done elsewhere in this function.

2016-09-01EDAC, fsl_ddr: Fix IRQ dispose warning when module is removedYork Sun1-3/+1
When compiled as a module, removing it causes kernel warnings when irq_dispose_mapping() is called. Instead of calling irq_of_parse_and_map(), use platform_get_irq() to acquire the IRQ number.

2016-09-01EDAC, fsl_ddr: Add support for little endianYork Sun1-40/+56
Get endianness from device tree. Both big endian and little endian are supported. Default to big endian for backwards compatibility to MPC85xx.

2016-09-01EDAC, fsl_ddr: Add missing DDR DRAM typesYork Sun1-8/+16
The compatible DDR controllers may support DDR, DDR2, DDR3, DDR4 DRAM. An individual controller doesn't support all of them. The EDAC driver reads SDRAM_CFG to determine which mode is configured. Add DDR4 and drop the defines used only in the mtype assignment.

The mpc85xx-compatible DDR controllers are used on ARM-based SoCs too. Carve out the DDR part from the mpc85xx EDAC driver in preparation to support both architectures.
