Rostislav Lisovy 1dc338e856 mtd: nand: omap: Synchronize the access to the ECC engine ... The AM335x Technical Reference Manual (spruh73j.pdf) says "Because the ECC engine includes only one accumulation context, it can be allocated to only one chip-select at a time ... " (7.1.3.3.12.3). Since the commit 97a288ba2c ("ARM: omap2+: gpmc-nand: Use dynamic platform_device_alloc()") gpmc-nand driver supports multiple NAND flash devices connected to the single controller. Use global 'struct nand_hw_control' among multiple NAND instances to synchronize the access to the single ECC Engine. Tested with custom AM335x board using 2x NAND flash chips.
