- parallel NOR flash - parallel NAND flash - OneNand flash - SDR RAM - Ethernet Devices like LAN9220 Though GPMC configurations may be different for each platform depending on clock-frequency and external device interfacing with controller. But initialization sequence remains common across all platfoms. Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c files into single omap-common/mem-common.c However, actual platforms specific register config values are still sourced from corresponding platform specific headers like;

Corresponding trap_size should be deducted from total SDRAM size only if trap section is overlapping with available SDRAM based on DMM sections. Fixing the same.
