mips: Add a reset_cpu() function

2023-12-21T21:07:52+00:00

The current do_reset() is called from a command context. Add a function
which can be used from anywhere, as is done on ARM.

mips: Remove common.h usage

2023-10-24T20:34:45+00:00

We can remove common.h from most cases of the code here, and only a few
places need an additional header instead.

spl: Use SYS_MALLOC_F instead of SYS_MALLOC_F_LEN

2023-10-06T18:38:12+00:00

Use the new SPL/TPL/VPL_SYS_MALLOC_F symbols to determine whether the
malloc pool exists.

mips: cpu: Use plain puts() in restart handler

2023-06-24T17:46:55+00:00

This removes dependency on fprintf() , which is not available
in SPL unless full printf support is enabled.

mips: add __image_copy_len for SPL linker script

2022-07-13T21:03:37+00:00

This patch adds __image_copy_len needed by TPL of MT7621 SoC.
The __image_copy_len represents the binary blob size of both SPL/TPL
binaries. To achieve this, __text_start/end are added for calculation.

linker_lists: Rename sections to remove . prefix

2022-06-23T16:58:18+00:00

Rename the sections used to implement linker lists so they begin with
'__u_boot_list' rather than '.u_boot_list'. The double underscore at the
start is still distinct from the single underscore used by the symbol
names.

Having a '.' in the section names conflicts with clang's ASAN
instrumentation which tries to add redzones between the linker list
elements, causing expected accesses to fail. However, clang doesn't try
to add redzones to user sections, which are names with all alphanumeric
and underscore characters.

Migrate CUSTOM_SYS_INIT_SP_ADDR to Kconfig using system-constants.h

2022-06-06T16:09:19+00:00

- Make all users of CUSTOM_SYS_INIT_SP_ADDR reference SYS_INIT_SP_ADDR
- Introduce HAS_CUSTOM_SYS_INIT_SP_ADDR to allow for setting the stack
  pointer directly, otherwise we use the common calculation.
- On some platforms that were using the standard calculation but did not
  set CONFIG_SYS_INIT_RAM_SIZE / CONFIG_SYS_INIT_RAM_ADDR, set them.
- On a small number of platforms that were not subtracting
  GENERATED_GBL_DATA_SIZE do so now via the standard calculation.
- CONFIG_SYS_INIT_SP_OFFSET is now widely unused, so remove it from most
  board config header files.

Convert CONFIG_SKIP_LOWLEVEL_INIT et al to Kconfig

2021-08-31T21:47:49+00:00

This converts the following to Kconfig:
   CONFIG_SKIP_LOWLEVEL_INIT
   CONFIG_SKIP_LOWLEVEL_INIT_ONLY

In order to do this, we need to introduce SPL and TPL variants of these
options so that we can clearly disable these options only in SPL in some
cases, and both instances in other cases.

mips: enable _machine_restart for spl

2021-01-24T20:39:26+00:00

The sysreset driver has a config CONFIG_SPL_SYSRESET for the spl stage.
Change CONFIG_SYSRESET to CONFIG_IS_ENABLED(SYSRESET) will give spl a
chance to use _machine_restart instead of the sysreset driver.

mips: start.S: Add Octeon boot header compatibility

2020-11-30T17:31:56+00:00

Octeon has a specific boot header, when booted via SPI NOR, NAND or MMC.
Here the only 2 instructions are allowed in the first few bytes of the
image. And these instructions need to be one branch and a nop. This
patch adds the necessary nop after the nop, to that the common MIPS
image is compatible with this Octeon header.

The tool to patch the Octeon boot header into the image will be send in
a follow-up patch.
