[PATCH v4 0/4] mips: Add initial Octeon MIPS64 base support

[Stefan Roese]

This patch adds very basic support for the Octeon III SoCs. Only CFI
parallel UART, reset and NOR flash are 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.

v3:
This version is based on the MIPS start.S rework and Linux header sync
from Daniel using this branch: u-boot-mips/header_sync_v2

I removed the very early copy to to L2 cache for now to make the
integration into mainline easier. With all the patches already applied
and the Linux header sync, the resulting patchset is much smaller.

Thanks,
Stefan

Changes in v4:
- Remove custom clock API
- Remove bitfield and use GENMASK etc
- Add ioremap and use physical addresses
- Remove CONFIG_BOARD_SIZE_LIMIT

Changes in v3:
- Don't "relocate" to L2 cache for now
- Remove inclusion of "common.h"
- Remove inclusion of "common.h"
- Slightly change some copyright messages (adjust year)

Changes in v2:
- Remove custom start.S and use common start.S. Minimal custom lowlevel
  init code is currently added in the custom lowlevel_init.S. This needs
  to be extended with necessary code, like errata handling etc. But for
  a very first basic port, this seems to be all thats needed to boot on
  the EBB7304 to the prompt.
- Removed select CREATE_ARCH_SYMLINK
- Removed Octeon II support, as its currently no added in this patchset
- Added cache.c to add the platform specific cache functions as no-ops
  for Octeon as the platform is cache coherent
- Removed CONFIG_MIPS_CACHE_COHERENT
- Added CONFIG_CPU_CAVIUM_OCTEON to Kconfig and selected it for Octeon
  to enable better sync with the Linux files in the future
- Add get_tbclk() -> no need to define CONFIG_SYS_MIPS_TIMER_FREQ any more
- Removed CONFIG_SYS_MIPS_TIMER_FREQ
