[PATCH v5 0/4] edac: Add APM X-Gene SoC EDAC driver

[lho@apm.com (Loc Ho)]

This patch adds support for the APM X-Gene SoC EDAC driver.

v5:
* Rebase to 3.17.rc1 (next)
* Update binding documentation for additional SoC node binding resource
* Enable MCU correctable and uncorrectable interrupts if not enabled by
  firmware
* Enable top level interrupt only after all MCU registered. Otherwise,
  error interrupt will never get cleared by the corresponding MCU.
* Remove clearing of L1 and L2 errors during initialization time. Otherwise,
  they will not be captured between firmware booting and error configuration.
* Add capture and clearing SoC register bus errors
* Add register bus resource to SoC DT node

v4:
* Fix PMD l1/l2 error reading address due to wrong variable type
* Fix clearing of software generated and HW errors for l1/l2

v3:
* Update binding documentation for PMD DT node and exampples
* Add binding documentation for SoC DT node
* Change MC, PMD, and L3C driver error injection to use debugfs
* Add missing IRQ for MC correctable error (code and DT)
* Use true/false where appropriate instead 1/0
* Add bit definition for L1 MMUESR register and fully decode this error
* Remove the un-necessary dev variable from xgene_edac_pmd_ctx structure
* Add check for disabled PMD (code and DT)
* Switch to edac_printk instead pr_err
* Some minor comments update

v2:
* Add EDAC entry in MAINTAINERS for APM EDAC driver
* Remove the MC scrub patch
* Remove the word 'Caches' from Kconfig
* Change all MASK defines to use BIT(x)
* Update comment or remove them
* Wrap error injection code around CONFIG_EDAC_DEBUG
* Change function name xgene_edac_mc_hw_init to xgene_edac_mc_irq_ctl
* Change all function XXX_hw_init to XXX_hw_ctl
* Fix typo 'activie'
* Move calling function edac_mc_alloc after resource retrieval
* Check for NULL on platform_get_resource return if reference directly
* Add documentation for struct xgene_edac_pmd_ctx
* Move L1 and L2 check out of function xgene_edac_pmd_check to its own
  functions
* Use for loop for configure each CPU of an PMD
* Replace /2 by >> 1
* Remove unnecessary comment on edac_device_add_device failure
* Make mem_err_ip static const
* Unwind EDAC register correctly if failed
