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

mtd: Make CONFIG_MTD be the gate symbol for the menu

2024-01-22T19:18:54Z

The help for CONFIG_MTD explains that it needs to be enabled for various things like NAND, etc to be available. It however then doesn't enforce this dependency and so if you have none of these systems present you still need to disable a number of options. Fix this by making places that select/imply one type of flash, but did not do the same, also do this for "MTD". Make boards which hadn't been enabling MTD already but need it now, do so. In a few places, disable CONFIG_CMD_MTDPARTS as it wasn't previously enabled but was now being implied. Signed-off-by: Tom Rini

Merge patch series "Complete decoupling of bootm logic from commands"

2023-12-21T21:10:00Z

Simon Glass says: This series continues refactoring the bootm code to allow it to be used with CONFIG_COMMAND disabled. The OS-handling code is refactored and a new bootm_run() function is created to run through the bootm stages. This completes the work. A booti_go() function is created also, in case it proves useful, but at last for now standard boot does not use this. This is cmdd (part d of CMDLINE refactoring) It depends on dm/bootstda-working which depends on dm/cmdc-working

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

mips: Add a reset_cpu() function

2023-12-21T21:07:52Z

The current do_reset() is called from a command context. Add a function which can be used from anywhere, as is done on ARM. Signed-off-by: Simon Glass

global: Rework architecture global_data.h to include
