Add SPINAND_HAS_CR_FEAT_BIT flag to identify the SPI NAND device with the Continuous Read mode. Some of the Micron SPI NAND devices have the "Continuous Read" feature enabled by default, which does not fit the subsystem needs. In this mode, the READ CACHE command doesn't require the starting column address. The device always output the data starting from the first column of the cache register, and once the end of the cache register reached, the data output continues through the next page. With the continuous read mode, it is possible to read out the entire block using a single READ command, and once the end of the block reached, the output pins become High-Z state. However, during this mode the read command doesn't output the OOB area. Hence, we disable the feature at probe time.

Add a way to run a function on a selection of CPUs. This supports either a single CPU, all CPUs, just the main CPU or just the 'APs', in Intel terminology. It works by writing into a mailbox and then waiting for the CPUs to notice it, take action and indicate they are done. When SMP is not yet enabled, this just calls the function on the main CPU.

This patch adds very basic minimal support for the Marvell Octeon 3 CN73xx based EBB7304 EVK. Please note that the basic Octeon port does not support DDR3/4 initialization yet. To still use U-Boot on with this port, the L2 cache (4MiB) is used as RAM. This way, U-Boot can boot to the prompt on this board.

This patch adds the code to copy itself from bootrom location to a different location (TEXT_BASE) to the Octeon platform. Its used in this case to copy the complete U-Boot image into L2 cache, which greatly improves the bootup time - especially in regard to the very long and complex DDR4 init code. The Kconfig symbol CONFIG_MIPS_MACH_EARLY_INIT is enabled with this patch for Octeon. Signed-off-by: NStefan Roese <sr@denx.de>
