MIPS: new Kconfig option ZBOOT_LOAD_ADDRESS

2022-01-02T13:17:30+00:00

If this option is not 0x0, it will be used for zboot load address.
Otherwise, the result of calc_vmlinuz_load_addr will be used.

The zload-y value for generic are also removed then, as the current
value breaks booting on qemu -M boston.
The result of calc_vmlinuz_load_addr works well for most of cases.

The default value of bcm47xx keeps as it currently.

MIPS: enable both vmlinux.gz.itb and vmlinuz for generic

2022-01-02T13:17:00+00:00

vmlinux.gz.itb should be appended to all-$(CONFIG_MIPS_GENERIC)
instead of replacing. Otherwise, no vmlinuz will be built.

MIPS: generic: enable SMP on SMVP systems

2021-12-21T12:51:47+00:00

In addition to CPS SMP setups, also try to initialise MT SMP setups with
multiple VPEs per CPU core. CMP SMP support is not provided as it is
considered deprecated.

Additionally, rework the code by dropping the err variable and make it
similar to how other platforms perform this initialisation.

MIPS: generic/yamon-dt: fix uninitialized variable error

2021-11-16T08:27:01+00:00

In the case where fw_getenv returns an error when fetching values
for ememsizea and memsize then variable phys_memsize is not assigned
a variable and will be uninitialized on a zero check of phys_memsize.
Fix this by initializing phys_memsize to zero.

Cleans up cppcheck error:
arch/mips/generic/yamon-dt.c:100:7: error: Uninitialized variable: phys_memsize [uninitvar]

MIPS: ingenic: Unconditionally enable clock of CPU #0

2021-08-29T11:31:02+00:00

Make sure that the PLL that feeds the CPU won't be stopped while the
kernel is running.

This fixes a problem on JZ4760 (and probably others) where under very
specific conditions, the main PLL would be turned OFF when the kernel
was shutting down, causing the shutdown process to fail.

MIPS: generic: Allow generating FIT image for Marduk board

2021-08-12T14:01:49+00:00

Marduk is based on IMG pistachio SoC. The platform is using
MIPS UHI booting protocol and does have a proper devicetree
implement, thus it could be a part of generic kernel.

MIPS: generic: Update node names to avoid unit addresses

2021-04-12T14:48:35+00:00

With the latest mkimage from U-Boot 2021.04, the generic defconfigs no
longer build, failing with:

/usr/bin/mkimage: verify_header failed for FIT Image support with exit code 1

This is expected after the linked U-Boot commits because '@' is
forbidden in the node names due to the way that libfdt treats nodes with
the same prefix but different unit addresses.

Switch the '@' in the node name to '-'. Drop the unit addresses from the
hash and kernel child nodes because there is only one node so they do
not need to have a number to differentiate them.

MIPS: of: Introduce helper function to get DTB

2021-02-04T12:34:51+00:00

Selection of the DTB to be used was burried in more or less readable
code in head.S. Move this code into a inline helper function and
use it.
