5fef24c912 mips: octeon: Add minimal Octeon 3 EBB7304 EVK support
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.

Supported devices:
- UART
- reset
- CFI parallel NOR flash

e9609dc38b mips: octeon: use mips_mach_early_init() to copy to L2 cache
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.

0dc4ab9c43 mips: octeon: Initial minimal support for the Marvell Octeon SoC
This patch adds very basic support for the Octeon III SoCs. Only
CFI parallel NOR flash and UART is supported for now.

Please note that the basic Octeon port does not include the DDR3/4
initialization yet. This will be added in some follow-up patches
later. To still use U-Boot on with this port, the L2 cache (4MiB on
Octeon III CN73xx) is used as RAM. This way, U-Boot can boot to the
prompt on such boards.
