for network functionality.

787e0d7d12 mips: octeon: cpu.c: Move bootmem init to arch_early_init_r() 
Call octeon_bootmem_init() earlier in the boot process, so that this
bootmemory infrastructure is already initialized when e.g. the
networking support gets probed.

185f812c41 doc: replace @return by Return: 
Sphinx expects Return: and not @return to indicate a return value.

6094145958 mips: octeon: cpu.c: Enable AHCI/SATA support 
For easy AHCI/ SATA integration, this patch adds board_ahci_enable()
for the MVEBU AHCI driver, which will be used by this platform. This
platform specific "enable" function will setup the proper endian
swapping in the AHCI controller so that it can be used by the common
AHCI code.

Additionally the endian swizzle entry for AHCI in
octeon_should_swizzle_table[] is removed, as this enabled the original
lowlevel code function, e.g. octeon_configure_qlm(), for the QLM setup
to work correctly.

480fa8346b mips: octeon: cpu.c: Add arch_misc_init() for pci-console & pci-bootcmd 
This patch adds the necessary platform infrastructure code, so that the
MIPS Octeon drivers "serial_octeon_pcie_console" & "serial_bootcmd" can
be used. This is e.g. the bootmem initialization in a compatible way to
the Marvell 2013 U-Boot, so that the exisiting PC remote tools like
"oct-remote-console" & "oct-remote-load" can be used. This is be done in
the newly introduced arch_misc_init(), which calls the necessary init
functions when enabled.

These patches are in preparation for the MIPS Octeon NIC23 board
support, which is a desktop PCIe target board enabling these features.

fd569c878b mips: octeon: cpu.c: Add table for selective swapping 
Import octeon_should_swizzle_table[] which is needed for the area
specific swapping. It will be used by the platform specific
mangle-port.h header.

Imported from Linux v5.7.

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.
