mips: fix change_k0_cca()

2024-03-13T20:15:40Z

The intention of change_k0_cca() is to read the C0.Config register into register $t0, update $t0 with the new cache coherency mode passed in $a0 and write back $t0 to C0.Config. With MIPS32 R2 or later instruction sets, this can be achieved with a single instruction with INS. The source and destination register of the INS instruction is passed as first parameter. In case of change_k0_cca() it is register $t0. But for writing back the updated value to C0.Config, the incorrect $a0 register is used. This is only correct in the MIPS32 R1 code path. Fix the `mtc0` instruction to write back the value of the $t0 register. Fix the MIPS32 R1 code path to also store the updated value in $t0.

mips: implement __udivdi3

2024-03-13T20:15:40Z

Squashfs wasn't compiling because the lldiv() directives turn into __udivdi3 and we are using private libgcc. After this squashfs compiles for MIPS. Signed-off-by: Linus Walleij Signed-off-by: Daniel Schwierzeck Tested-by: Bartel Eerdekens

bootm: Rename do_bootm_states() to bootm_run_states()

2023-12-21T21:07:52Z

Rename the function to bootm_run_states() to better indicate ts purpose. The 'do_' prefix is used to indicate a command processor, which this is now not. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

bootm: Adjust arguments of boot_os_fn

2023-12-21T21:07:52Z

Adjust boot_os_fn to use struct bootm_info instead of the separate argc, argv and image parameters. Update the handlers accordingly. Few of the functions make use of the arguments, so this improves code size slightly. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

boot: Drop size parameter from image_setup_libfdt()

2023-12-13T23:39:05Z

The of_size parameter is not used, so remove it. Signed-off-by: Simon Glass Reviewed-by: Tom Rini

mips: Remove common.h usage

2023-10-24T20:34:45Z

We can remove common.h from most cases of the code here, and only a few places need an additional header instead. Signed-off-by: Tom Rini

treewide: unify the linker symbol reference format

2023-08-09T13:21:42Z

Now all linker symbols are declared as type char[]. Though we can reference the address via both the array name 'var' and its address '&var'. It's better to unify them to avoid confusing developers. This patch converts all '&var' linker symbol refrences to the most commonly used format 'var'. Signed-off-by: Shiji Yang Reviewed-by: Tom Rini

Correct SPL uses of BOOTSTAGE_REPORT

This converts 2 usages of this option to the non-SPL form, since there is no SPL_BOOTSTAGE_REPORT defined in Kconfig Signed-off-by: Simon Glass

global: Move remaining CONFIG_SYS_SDRAM_* to CFG_SYS_SDRAM_*

2022-12-05T21:06:07Z

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini Reviewed-by: Simon Glass
